 Description: Program to find the value of y for a particular value of n. The a, x, b, n is input by user
 if n = 1     y = ax % b
 if n = 2     y = ax² + b²
 if n = 3     y = a - bx
 if n = 4     y = a + x/b

#include <stdio.h>

int main (void)
{
    int a, x, b, n;
    float y;
    
    //Input a, x, b, n
    printf ("Input a: ");
    scanf ("%d", &a);

    //Calculate y on the basis of n
    switch (n)
    {
    case 1:
        printf ("y = ax % b = ");
        y = (a * x) % b;
        break;
    case 2:
