C Language program to find factorial of a number. It is a simple calculation of a factorial method. This is a basic C tutorial for beginners. Sample source code for this program is given below,

This C program is used to find the factorial series for “n” numbers. For example if the factorial is 3, then the calculation will be like this (3! = 3x2x1=6). It will calculate every values by using the looping statement of for loop (for(cn=num;cn>1;cn–)).
