Fundamentals of Computer Programming - Unit Wise Questions

1. Draw the flow chart for finding largest of three numbers and write an algorithm and explain it.

3. Write a program for the interest charged in installments for following case. A cassette player costs Rs. 2000. A shopkeeper sells it for Rs. 100 down payment and Rs. 100 for 21 more months. What is the monthly interest charged?

2. Find the value of “a” in each of the following statements:

int i=3 , j=4 ,k=8

float a=4.5 ,b=6.5,c=3.5

(a) a = b- i/k +c/k

(b) a = (b-k)/j + (j + c)/k

(c) a = c-(( i + j)/(k + i))*b

(d) a = c – i + j / k+ i * b

(e) a = c + j % 2 +b

(f) a = (b + 1) % (c + 1).

2. Determine which of the following are valid identifiers? If invalid, explain why?

(a) record1 (b)record

(c) file_3 (d) return

(e) #tax (f) name

(g) goto (h) name and address

(i) name-and-address (j) 123-45-6789

(k) Void (l) name_address

3. Write a program to find the factorial of a given integer.

7. Write a program to count the number of words in a sentence.

4. Write a program that uses a “for” loop to compute and prints the sum of a given numbers of squares.

3. Define printf() function, header file and main function. Find the value of following expression. Use the value initially assigned to the variables for each expressions.   [4.5+1.5]

int a = 8, b = 5;

float x = 0.005, y = -0.01;

1) 2 * ((a / 5) + 4 * (b – 3)) % (a + b - 2));

2) (x > y) && (a > 0) || (b < 5);

3) (a > b)?a:b;
