Simple C Program with Algorithm, Flowchart, Output - Computer Programming - C

Write a program to swap the contents of two variables using pointers.

AIM

To write a program to swap the contents of pointer variable

ALGORITHM

Step‒1: Start

Step-2 : Read input values a,b

Step-3 : Call function interchange ()

Step-4 : Print values of a,b

Step-5 : Stop

Step‒1 : Function Interchange start

Step-2 : swap (x,y)

Step-3 : return

FLOWCHART

PROGRAM

#include<stdio.h>

#include<conio.h>

void interchange(int *x,int *y)

{

int temp;

temp=*x;

*x=*y;

*y=temp;

}

void main()

{

int a,b;

clrscr();

printf("Enter the values A and B :");

scanf("%d %d",&a,&b);

printf("a=%d b=%d\n",a,b);

interchange(&a,&b);

printf("After interchanging : \n");

printf("a=%d b=%d\n",a,b);

getch();

}

OUTPUT

Enter the values A and B : 23 56

a=23 b=56

After interchanging :

a=56 b=23
