Program to show swap of two no’s without using the third variable.
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
printf("enter value for a & b: \n");
scanf("%d%d",&a,&b);
printf("Before swapping the value of a=%d & b=%d \n",a,b);
a=a+b;
b=a-b;
a=a-b;
printf("After swapping the value of a=%d & b=%d \n",a,b);
}
enter value for a & b:
2 3
Before swapping the value of a=2 & b=3
After swapping the value of a=3 & b=2

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
