Write a program to find the factorial of a number

Program Code

#include"stdio.h"
int main()
{
	int n, c;
	long int f=1;
	printf("\n Enter the number:");
	scanf("%d",&n);
	if(n<0)
		goto end;
	for(c=1; c<=n; c++)
		f*=c;
	printf("\n FACTORIAL IS %ld", f);
	end:
        
     getch();   
	return 0;
}

Output

 Enter the number:5

 FACTORIAL IS 120

Explanation

None

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
