Program #1: Write a c program to perform arithmetic operations using switch case



  1. #include <stdio.h>
  2. #include <conio.h>
  3.  
  4. int main()
  5. {
  6.     char oper;            /* oper is an operator to be selected */
  7.     float n1, n2, result;
  8.  
  9.     printf ("Simulation of a Simple Calculator\n\n");
  10.  
  11.     printf("Enter two numbers\n");
  12.     scanf ("%f %f", &n1, &n2);
  13.  
  14.     fflush (stdin);
  15.  
  16.     printf("Enter the operator [+,-,*,/]\n");
  17.     scanf ("%c", &oper);
  18.  
  19.     switch (oper)
  20.        {
  21.         case '+': result = n1 + n2;
  22.               break;
  23.         case '-': result = n1 - n2;
  24.               break;
  25.         case '*': result = n1 * n2;
  26.               break;
  27.         case '/': result = n1 / n2;
  28.               break;
  29.         default : printf ("Error in operation\n");
  30.               break;
  31.     }
  32.  
  33.     printf ("\n%5.2f %c %5.2f= %5.2f\n", n1,oper, n2, result);
  34. getch();
  35. }


Output:
