write a program find factorial of any number in c++

C++ Program to Find Factorial


In this program,we learn to calculate the factorial of num using for loop in this program.

You must have basic knowledge of  C++ programming language and variable  , while loop and if..ealse and for loop

Write a program to find the factorial of any number.


We every number is equal to 1*2*3*4*5*..n.You must have basic knowledege of programming language before start program.To understand this program ,you must have the knowledge of c++ programming topics such as for loop and basic syntax.





For any number ,This is factorial number is given by


[factorial = 1*2*3*4*5*6*..........*n]




Example 1: Find Factorial of a given number by user

In this factorial program  given value through the user.

#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
int n=;
int fact;

 cout << "Plz enter the any postive number";
 cin>>n;

for(i=1;i<=n;i++)
{
fact=fact*i;
}
 cout << n<<"Factorial number is="<<fact;

return 0
getch();
}


output
----------------------------------------------
Plz enter the any postive number
5

The greatest number is:120



Example 2: Find Factorial of a given number


#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
int n=4;
int fact;


for(i=1;i<=n;i++)
{
fact=fact*i;
}
 cout << n<<"Factorial number is="<<fact;

return 0
getch();
}

Result
----------------------------------------------


The greatest number is:120



You should have basic programming knowledege
like syntax and variable and if else statement or for loop that is must learn before starting
the program.
