C Program to Calculate Factorial of a Number | For Loop Example in C
In this tutorial, you will learn how to write a factorial program in C using a for loop. This video explains the logic of factorial calculation in C with simple examples such as 0!, 1!, 3!, and 6!.
We walk through a complete C program to calculate the factorial of a number entered by the user, using an unsigned long long integer to handle large values. You will also understand why factorial values grow very fast and how to restrict user input between 0 and 20 to avoid overflow issues.
What you will learn:
What is factorial in C programming
Factorial program logic in C
Factorial using for loop in C
Handling large numbers in C
