Practical - 2
Aim: Write a program to swap the value of two variables using third variable.
Program:
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a, b, c;
printf("Enter the value of 'A'
= ");
scanf("%d", &a);
printf("Enter the value of 'B'
= ");
scanf("%d", &b);
c = a;
a = b;
b = c;
printf("\nA = %d", a);
printf("\nB = %d", b);
getch();
}
Output:
Enter
the value of 'A' = 4
Enter
the value of 'B' = 5
A
= 5
B
= 4
Algorithm:
Step-1:
START
Step-2:
Declare a, b, c.
Step-3:
Enter the value of a and b.
Step-4:
c = a.
Step-5:
a = b.
Step-6:
b = c.
Step-7:
Display a and b.
Step-8:
STOP.
