12.  Write a computer program that will generate three digit random numbers using the linear congruential method. Allow the user to input values of X₀, a, c and m.

# include<stdio.h>

#include<conio.h>

#include<math.h>

int main()

{

    int x[10],n, a, c, m, i, j;

    float r[10];

    printf("Enter the number of random number to generate:");

    scanf("%d", &n);

    printf("Enter the value of seed x₀:);

    scanf("%d", &x[0]);

    printf("Enter the value of a:");

    scanf("%d", &a);

    printf("Enter the value of c:");

    scanf("%d", &c);

    printf("Enter the value of m:");

    scanf("%d", &m);

    i=0;

    r[0] = float(x[0]/m);

    if (m ==1000)       

    {    

        do{

                x[i+1] = (a*x[i]+c)%m;

                r[i+1] = float(x[i+1]/m);

                i++;

            }while(i<=n);

        printf("The obtained random numbers are:");

        for(j=0; j<n; j++)

        {

            printf("%f", &r[j];

        }

else{

    printf("To generate three digit random number the value of m should be 1000 !!");

}

return 0;
