The program is to find the factorial of number using function.

The program is not extendable.

 Go enjoy the program. Lets begin… 

#include<iostream.h>
#include<conio.h>
//function prototype
int fact(int);
//main function
void main()
{
//clear the screen.
clrscr();
//declare variables as int.
int no,fac;
//Input the number and save it in 'no'
cout<<"Enter the no."<<endl;
cin>>no;
//calculate factorial using function.
fac=fact(no);
//print factorial
cout<<"Factorial of "<<no<<" is "<<fac;
//get character
getch();
}

//function
int fact(int no)
{
int i,f=1;
for(i=1;i<=no;i++)
f=f*i;
return(f);
}
