3. Describe the four basic data types with example.
Data type in C refers to an extensive system used for declaring variable for function of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted.
The Four basic data types are described below:
1. Integer type (int):
- Integers are whole numbers.
- It requires 16 bit of storage i.e. 2 bytes.
- Three classes of integer: Integer(int), Short integer (short int) and Long integer (long int)
E.g. int a; int x=5;
2. Floating point type (float):
- Floating point type are fractional numbers.
- A variable of float type requires 4 bytes and the range of values that can be stored in it, is 3.4e-38 to 3.4e+38.\\
- Variable is defined as:
float a;
float x=23.7;
3. Character type (char):
- All single character used in programs belong to character type.
- The character data type holds exactly 8 bits (1 byte).
- The unsigned char has values between 0 and 255.
- The signed char has values from -128 to 127.
- Variable is declared as:
char var1= ‘h’;
Here, var1 is a variable of type char which is storing a character ‘h’.
4. Double precision floating point type (double):
i. Double precision:
- It reserves 8 bytes in memory.
- It represents fractional number of the range 1.7e-308 to 3.4e+308
ii. Long double precision:
- It reserves 10 bytes in memory.
- It represents fractional numbers of the range 3.4e-4932 to 1.1e+4932

2. What are the different types of operators available in C?Explain.
An operator is a symbol that operates on single or multiple data items. It is used in program to perform certain mathematical or logical manipulations. E.g. In a simple expression 2+3, the symbol “+” is called an operator which operates on two data items 2 and 3.
C operators can be classified into following types:
1. Arithmetic Operators
Arithmetic operators are used to perform arithmetic operations. There are five arithmetic operators:
2. Relational Operators
- Relational operators are used to compare two operands and taking decisions based on their relation.
- Result of relational expression is either True(1) or False(0).
- Relational operators are used in decision making and loops.
- Relational operators are:
3. Logical Operators
- Logical operators are used to compare logical and relational expression.
- The operands of logical operators must be either Boolean value (1 or 0) or expression that produces Boolean value.
- The output of these operators is always 0 (flase) or 1 (true).
The logical operators are:
4. Assignment Operator
- Assignment operators are used to assign the result of an expression to a variable.
- The mostly used assignment operator is ‘=’.
- C also supports shorthand assignment operators which simplify operation with assignment.
5. Increment and Decrement Operators
- Increment operator is used to increase the value of an operand by 1.
- Decrement operator is used to decrease the value of an operand by 1.
6. Conditional Operator (Ternary Operator)
- It takes three arguments.
- Conditional operators return one value if condition is true and returns another value if condition is false.
Syntax: (condition) ? value_if_true : value_if_false
etc.

2. What is operator? List any six operators used in C-programming language. Write a program to find least number between any two numbers using ternary operator. [1+2+3]
An operator is a symbol that operates on single or multiple data items. It is used in program to perform certain mathematical or logical manipulations.
E.g. In a simple expression 2+3, the symbol “+” is called an operator which operates on two data items 2 and 3.
C operators can be classified into following types:
- Arithmetic Operators
- Relational Operators
- Logical Operators
- Assignment Operators
- Increment and Decrement Operators
- Conditional Operators
Program to find least number between any two numbers using ternary operator:
#include <stdio.h>
#include<conio.h>
int main()
{
int n1, n2,least;
printf("Enter two numbers: ");
scanf("%d%d", &n1, &n2);
least = n1<n2 ? n1:n2;
printf("The least number is %d",least);

4. Differentiate between while and do while loop with example.
Difference between while and do while loop
1. The while loop is pre-test loop, where firstly the condition is checked and if the condition is true then only the statements of the while loop execute. The do-while loop is a post-test loop. In the do-while loop, the statements of the do-while loop are executed after that, the condition is evaluated, and if the condition is true then again the statements of the do-while loop are executed.
2.
Syntax of while loop:
while (condition)
{
// statements
}
Syntax of the do-while loop:
do
{
// statements
} while(condition);
3. The condition of the while loop is at the top of the loop but the condition of the do-while loop is at the bottom of the loop.
4. While loop can’t be terminated with a semicolon but the do-while loop should be terminated with a semicolon.
5. The statements of the do-while loop execute at least 1 time in every condition. In the while loop, the test expression evaluates false in first checking then the statements of the while loop is not executed. But the condition of the do-while loop is checked at the end of the loop, so it is guaranteed that the statements of the do-while loop execute at least once.
Example of while loop:
#include<stdio.h>
int main()
{
int m,n;
printf("Enter range: ");
scanf("%d %d",&m, &n);
while (m<=n)
{
if(m%2==0)
printf("%d ",m);
++m;
}
return 0;
}
Example of do while loop:
#include<stdio.h>
int main()
{
int m,n;
printf("Enter range: ");
scanf("%d %d",&m, &n);
do
{
if(m%2==0)
printf("%d ",m);
++m;
} while(m<=n);
return 0;
}

#include<stdio.h>
#include<conio.h>
#include<math.h>

{
int x=2, n=5, sum=0, i; clrscr();
for(i=1; i<=n; i++)
{
If(i%2==0)
sum==sum-pow(x,i);
else
sum=sum+pow(x,1);
}
Printf(“sum=%d”,sum); Getch();
}

4. Difference between if and switch statement. Write a program to read the marks of four subjects then find total, percentage and division according to given condition. [1+5]
Percentage Division
p ≥ 80 Distinction
80 > p ≥ 70 First division
70 > p ≥ 50 Second division
50 > p ≥ 40 Third division
Otherwise Fail.
Assume each subjects carrying 100 full marks and students must secure greater or equal to 40 in each subjects for division.
Difference between if and switch statement
1. SWITCH statement is easier to express for lengthy conditions when compared to an IF statement which gets more complex as the number of conditions grow and the nested IF comes into play.
2. SWITCH statement allows easy proofreading while testing and removing bugs from the source code whereas IF statement makes editing difficult.
3. Expression is evaluated and SWITCH statement is run according to the result of the expression that can be integer or logical while IF statement is run only if the result of the expression is true.
4. SWITCH allows expression to have integer based evaluation while IF statement allows both integer and character based evaluation.
5. SWITCH statement can be executed with all cases if the ‘break’ statement is not used whereas IF statement has to be true to be executed further.
Program
#include <stdio.h> int main() { int phy, chem, bio, math; float p, total;
/* Input marks of five subjects from user */ printf("Enter four subjects marks: "); scanf("%d%d%d%d", &phy, &chem, &bio, &math);
/* Calculate total */
total= (phy + chem + bio + math);
printf("Total marks = %f\\n", total);
/* Calculate percentage */
p = (phy + chem + bio + math) / 4.0;
printf("Percentage = %f\\n", p);
/* Find division according to the percentage */
if(p >= 90)
{
printf("Division: Distinction");
}
else if(p>=70 && p<80 )
{
printf("Division: First division");
}
else if(p>=50 && p<70)
{
printf("Division: Second division");
}
else if(p>=40 && p<50)
{
printf("Division: Third division");
}
else
{
printf("Fail");

Difference between break and continue statement
| Break | Continue |
| Break is used to break loop or iteration. | Continue continues the loop or iteration. |
| Used with switch case loop. | Not used with switch case. |
| Keyword used is "break". | Keyword used is "continue". |
| Breaks loop and allows coming out from it. | Allows iterating in the loop. |
| Control is transferred outside the loop. | Control remains in the same loop. |
E.g.
Output: 1, 2 | E.g.
Output: 1, 2, 4, 5 |

8. Differentiate between call by value and call by reference with example.
In call by value, a copy of actual arguments is passed to formal arguments of the called function and any change made to the formal arguments in the called function have no effect on the values of actual arguments in the calling function.
In call by reference, the location (address) of actual arguments is passed to formal arguments of the called function. This means by accessing the addresses of actual arguments we can alter them within from the called function.
In call by value, actual arguments will remain safe, they cannot be modified accidentally whereas In call by reference, alteration to actual arguments is possible within from called function; therefore the code must handle arguments carefully else you get unexpected results.
Example using Call by Value:
#include <stdio.h>
void swapByValue(int, int); /* Prototype */
int main() /* Main function */
{
int n1 = 10, n2 = 20;
/* actual arguments will be as it is */
swapByValue(n1, n2);
printf("n1: %d, n2: %d\\n", n1, n2);
}
void swapByValue(int a, int b)
{
int t;
t = a;
a = b;
b = t;
}
Example using Call by Reference:
#include <stdio.h>
void swapByReference(int*, int*); /* Prototype */
int main() /* Main function */
{
int n1 = 10, n2 = 20;
/* actual arguments will be altered */
swapByReference(&n1, &n2);
printf("n1: %d, n2: %d\\n", n1, n2);
}
void swapByReference(int *a, int *b)
{
int t;
t = *a;
*a = *b;
*b = t;

10. Define the graphics function. Write a program to draw a circle using graphics function.
C graphics using graphics.h functions can be used to draw different shapes, display text in different fonts, change colors and many more. Using functions of graphics.h in Turbo C compiler we can make graphics programs, animations, projects, and games. We can draw circles, lines, rectangles, bars and many other geometrical figures. We can change their colors using the available functions and fill them.
Program to draw a circle using graphics function
#include <stdio.h>
#include <graphics.h>
main()
{
int gd = DETECT, gm;
initgraph(&gd, &gm, "C:\\TC\\BGI");
circle(100, 100, 50);
