Data Structure Lab Programs - a program for swapping of two numbers using call by value and call by reference strategies.

Practical # 7

 

 

/* Write a program for swapping of two numbers using call by value and call by reference strategies. */

 

#include<stdio.h>

#include<conio.h>

void swap_ref(int*,int*);

void swap_value(int,int);

void main()

{

int a,b,c;

clrscr();

printf("Enter two no.=");

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

swap_value(a,b);

swap_ref(&a,&b);

getch();

}

void swap_value(int x,int y)

{

int z;

z=x;

x=y;

y=z;

printf("The value swap using call by value=%d%d",x,y);

}

void swap_ref(int *x,int *y)

{

int z;

z=*x;

*x=*y;

*y=z;

printf("\nThe value swap using call by value=%d%d",*x,*y);

}

 

Output:-

 

Enter two no.=7

8

 

The value swap using call by value=87

 

The value swap using call by value=87
