Caluclator by using C Programming:

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c,ch;

printf("Menu\n1.Addition\n2.Substraction\n3.Multiplication\n4.Division\n5.Modulo Division\nEnter your Choice:");

scanf("%d",&ch)

switch(ch)

{

case 1:

   printf("\nEnter value1:");

   scanf("%d",&a);
   printf("\nEnter value2:");
   scanf("%d",&b);
  c=a+b;
  printf("\nResult of Addition:",c);
  break;

case 2:

   printf("\nEnter value1:");

   scanf("%d",&a);
   printf("\nEnter value2:");
   scanf("%d",&b);
  c=a-b;
  printf("\nResult of Substraction:",c);
  break;

case 3:

   printf("\nEnter value1:");

   scanf("%d",&a);
   printf("\nEnter value2:");
   scanf("%d",&b);
  c=a*b;
  printf("\nResult of Multiplication:",c);
  break;

case 4:

   printf("\nEnter value1:");

   scanf("%d",&a);
   printf("\nEnter value2:");
   scanf("%d",&b);
  c=a/b;
  printf("\nResult of Division:",c);
  break;

case 5:

   printf("\nEnter value1:");

   scanf("%d",&a);
   printf("\nEnter value2:");
   scanf("%d",&b);
  c=a%b;
  printf("\nResult of Modulo Division:",c);
