User Defined Functions - C++

Okay so I'm trying to write my own function that will display the sum of all numbers up until the number inputted by the user.
Ex.
input = 5
the function will display
1+2+3+4+5.

So I'm needing to tell the function to add the sum + 1 until it gets to that given number, then stop. But I'm having trouble with that. I tried using a for loop.... but it's not really working for me. Any suggestions?

 

okay, pretty much figured it out. here's what i got.


#include <iostream>
using namespace std;

void displaySumOneToN( int nthDigit );
int main(void)
{
int number = 0;
cout << "Enter a number to sum: ";
cin >> number;
displaySumOneToN( number );

return 0;
}

void displaySumOneToN( int nthDigit )
{
int total = 0;
for( int i = 0; i <= nthDigit; i++ )
{
total = total + i;
}
cout << "The sum of all numbers up to " << nthDigit << " is: " << total << endl;
}





i was wondering if it's possible to display all of the numbers that are added up to the inputted number? instead of just the sum of all those numbers...

 

not sure exactly what you mean but can't you just put a
cout << i;
in your loop?
