Simple Calculator [ + , - , * , / ]

 Write a C program to simulate a simple calculator to perform arithmetic operations like      addition,subtraction,multiplication and division only on integers. 

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

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

int main()
{
 char oper;
 float n1, n2, result;

    printf ("Simple Calculator Simulation \n\n");

    printf("Enter two numbers\n");
 scanf ("%f %f",&n1,&n2);

 fflush (stdin);
    printf("Enter the operator [+,-,*,/]\n");
 scanf ("%c",&oper);

 switch (oper)
    {
  case '+': result = n1 + n2;
     break;
  case '-': result = n1 - n2;
     break;
  case '*': result = n1 * n2;
     break;
  case '/': result = n1 / n2;
     break;
  default : printf ("Error in operation\n");
     break;
 }

printf ("\n %5.2f %c %5.2f = %5.2f\n", n1,oper, n2, result);

return 0;
}
