Question

I need help creating a C++ program that computes the factorial of an integer between 1-20 using a nested loop. Integer and respective factorial must be printed in 2 columns on the screen.

Answer 1

Here's what I have so far. I don't know how to get the integers and factorials to print though :/

#include<iostream>

using namespace std;

int main()

{

int num,factorial=1;

cout<<" Enter Number To Find Its Factorial: ";

cin>>num;

for(int k=1; k<=num; k++)

{
factorial=factorial*k;
}

cout << "Interger" << " " << "Factorial" << endl;
cout << num << " " << factorial << endl;

system ("PAUSE");
return 0;

Answer 2

Can you please show me the output you are getting on console?

Answer 3

Integer Factorial
4 24

But according to the assignment it should also be showing the factorials for 1-3 as well.
17! and a few others are also coming up wrong and I have no idea how to fix those.

Answer 4

Can i do this in java?

Answer 5

Not really sure what that is other than another language. If it'll help solve the problem in C++ then I guess. It's a C++ class though.

Answer 6

Well Java is a object oriented language too,the only difference would be the syntax.

Answer 7

Oh okay. Well by all means. I'm just so frustrated with this.

Answer 8

Don't worry it's easy :)

Answer 9

here you go.

Answer 10

amorable, output the column headers before your for loop and output num and factorial inside the loop.

Answer 11

Do a loop from 1 to integer.
do the math
output "Integer" loopNumber "Factorial" factorial
close the loop

Answer 12

oh yeah, @rsmith6559 got it

Output "Integer" "Factorial"
Do a loop from 1 to integer.
do the math
output loopNumber factorial
close the loop
