find the factorial of a given number using c programming

Updated on March 24, 2010

To find the factorial of number, multiply continuously from 1 to that number.

for eg:- Factorial of 3 (ie. 3!) = 1 * 2 * 3 = 6

Factoria of 5 (ie. 5!) = 1 * 2 * 3* 4* 5 = 120

and so on.




void main()


int f=1,i,n;


printf("Enter a number\n");




f=f * i;



printf("Factorial of %d is %d",n,f);




NB: stdio.h -------------> header file

conio.h ----------> heade file

int f=1 ----------> variable declaration & assigning values

scanf ---------------> getting value to the variable n from keyboard

f=f*i ----------------> value of f is multiplied by the value of i and save the result in to f.

      Your program is wrong. intialize i=1 above while loop. Then the program will execute correctly.
