In this c program we are going to subtract any two given integers using functions and pointers and display the output.

C program to subtract any two integers 

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,sub;
clrscr();

printf("\n Enter Any Two Numbers To Subtract : ");
scanf("%d%d",&a,&b);

sub=a-b;

printf("\n Subtraction = %d",sub);

getch();
}
Output :

C program for Dev C++ to subtract two integers

#include<stdio.h>

int main()
{
int a,b,sub;

printf("\n Enter Any Two Numbers To Subtract : ");
scanf("%d%d",&a,&b);

sub=a-b;

printf("\n Subtraction = %d",sub);

getch();
return 0;
} 

Output :

Subtract any two numbers using functions in c

#include<stdio.h>
#include<conio.h>
int sub(int a,int b); //function declaration

void main()
{
 int result,x,y;
 clrscr();

 printf("\n Enter Any Two Numbers To Subtract : ");
 scanf("%d%d",&x,&y);

 result=sub(x,y); //calling the function

 printf("\n Subtraction = %d",result);

 getch();

 }

 int sub(int a, int b)  //definition of function
 {
  int c;

  c=a-b;

  return(c);
 }

C program to subtract any two given numbers using pointers

#include<stdio.h>
#include<conio.h>
void main()
{
 int *p1,*p2,a,b,sub;
 clrscr();

 printf("\n Enter Any Two Numbers To Subtract : ");
 scanf("%d%d",&a,&b);

 p1=&a;
 p2=&b;

 sub = *p1 - *p2;

 printf("\n Subtraction = %d",sub);

 getch();

}
In this way we can subtract two numbers in c programming.
