Simple Arithmetic Programs In C

I'll be posting C Programs with basic integral addition and subtraction as possible and for more understanding you can leave a comment below.

1. C Program to Add two Integers..

   
               #include <stdio.h>                   // for scanf and printf function
               #include <conio.h>                 // for clrscr() and getch()
               main()
               {
                   clrscr();                             // to clear the output screen
                   int a,b,add;                       // initializing 3 variable two for storing input and one for output
                   printf("\n Enter First Integer value");  // printing for user to understand the input
                   scanf("%d",&a);    // taking first integer value input
                   printf("\n Enter Second integer value"); 
                   scanf("%d",&b);   // taking second integer input
                   add=a+b;              // adding the values and storing it in variable add
                   printf("\n The Added value of %d and %d is %d", a,b,add);  // printing the added value
                   getch();                 // to hold the output screen until key print
                   return 0;               // main method returning no value
                 }

      //- Used to enter the comments and not executed by compiler during compilation.
            a single line comment.

2. C Program to Subtract two Integer value.

                #include < stdio.h >
               #include <conio.h>
               main()
               {
                   clrscr();
                   int a,b,subtract;
                   printf("\n Enter First Integer value");
                   scanf("%d",&a);
                   printf("\n Enter Second integer value");
                   scanf("%d",&b);
                   if(a>b)                       // checking which is bigger, i:e bigger-smaller , here a>b
                         subtract=a-b;
                   else
                       subtract=b-a;      // if ais not greater than b then b-a
                   printf("\n The subtracted value of %d and %d is %d", a,b,subtract);
                   getch();
                   return 0;
                 }

when a is  bigger than b

when b is bigger than a

C Program to multiply Two Number

       
           #include <stdio.h>                   // for scanf and printf function
           #include <conio.h>                 // for clrscr() and getch()
           main()
          {
          clrscr();                             // to clear the output screen
          int a,b,multiply;                       // initializing 3 variable two for storing input and one for output
          printf("\n Enter First Integer value");  // printing for user to understand the input
          scanf("%d",&a);    // taking first integer value input
          printf("\n Enter Second integer value"); 
          scanf("%d",&b);   // taking second integer input
          multiply=a*b;              // adding the values and storing it in variable add
         printf("\n The Added value of %d and %d is %d", a,b,multiply);  // printing the multiplied value
          getch();                 // to hold the output screen until key print
          return 0;               // main method returning no value
               }

 3. C Program to divide two number

     #include <stdio.h>

   #include <conio.h>
           
main()
{
int a,b; 
float divide;
printf("\n Enter first integer ");
scanf("%d",&a);
printf("\n Enter the second integer");
scanf("%d",&b);
if(a==0 || b==0 )  // in case if user uses 0 as value of any number
printf("\n Illegeal Division, Either of the number is 0");
else if(a{
divide=(float)b/a;   // TypeCast to float
printf("\n The value after division of %d and %d is %f ",a,b,divide);
}
else
{
divide=(float)a/b;   //typeCast to float
printf("\n The value after division of %d and %d is %f ",b,a,divide);
}
getch();
return 0;
}
