6. Write a 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

               y = (float) a + (float) x / (float) b;

               break;

          default:

               return 0;

     }

     //Print result

     printf ("%.2f", y);

     return 0;

};

Output

Input a: 5

Input x: 7
Input b: 3

Input n: 4

y = a + x/b = 7.33
