📘 Step Learning

In this program you will learn how to swap two numbers using c program.

📌 Information & Algorithm

Here we used concept of function.

Here we used concept of pointer.

Here we used temp pointer variable.

💻 Program Code

#include <stdio.h>
void swap(int *a, int *b)
{
	int temp;
	temp = *a;
	*a = *b;
	*b = temp;
}
int main()
{
	int x=5,y=10;
	void swap(int *,int *);
	printf("%d %d\n",x,y);
	swap(&x, &y);
	printf("%d %d\n",x,y);
	return 0;
}

🖥 Program Output

5 10
10 5

🎯 How to learn from this example

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.

🔥 Practice suggestion

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.
