What is the Program to find-out factorial of given number?

[Sheenas]

Hi Guys,

Is Anyone know the how to write the program to find-out factorial of given number?

When I run my program code for factorial, either the output prints wrong results or it goes into the indefinite looping. I referred different books but it doesn't works for me. I don't know how to proceed.

Please help me to find out the solution over this.

Hi all,

I have the program code of the to find out the factorial of the given number. Below program is in the C++ language. I have used simple For loop to find out the factorial:

#include<conio.h>
#include<iostream.h>

void main()
{

int x=0;
int Fact=1;

cout<<"Enter number to calculate Factorial:";
cin>>x;

for(int c=1;c<=x;c++)
{

Fact=Fact * c;

}

cout<<"Factorial of number <<x << is: "<<Fact;

getch();

}

Hi,

See something below can help you to write program to find-out factorial:

Code:

Class Fact_demo{

public static void main(String[] args)
{
try
{

BufferedReader d = new BufferedReader(
new InputStreamReader(System.in));
System.out.println("enter the number");
int j= Integer.parseInt(d.readLine());
double fact1= 1;
System.out.println("Factorial of " +j+ ":");

for (int k= 1; k<=a; k++)
{
fact1=fact1*k;
}

System.out.println(fact1);

}

catch (Exception e1)
{
System.out.println("Array is out of bounds");

}
}
}

If your looping concept is clear then it won't be difficult for you to write the factorial program. I suggest you to use the "While " loop condition for this. Refer below code:

while(z<=number)
{
factorial = factorial *z;
z++;
}

Have you tried below following programming logic to find-out factorial?

#include<conio.h>
#include<stdio.h>

void main()
{
int facto(int);
int num;
clrscr();
printf("Enter the number: ");
scanf("%d",&num);
printf("Factorial %d is: %d",num,facto(n));
getch();
}
int facto(int y)
{
int fact4;
if(y==1)
return(1);
else
fact4=y*facto(y-1);
return(fact4);
}

Hi friend,

I had solved the similar problem using different loop of the C. Please try to use nested loop to find out the factorial. I am telling you because nested loop is useful to test the very difficult conditions. Functions with return type is also useful to find out the factorial of the given number. Use "fact(int number)" function in your program.
