Help with a simple while statement

[Andrewcen16]

Write your question here.

// the code needs to display the string twice on the first line 
//four times on the second line and six times on the third
//But idk how to make it do that with the while loop 

#include <iostream>
#include <cmath>
#include <string>

using namespace std;

int main()
{
	string first; // holding the string value
	int temp = 3; // condition for while loop
	int second = 0; // counter variable
	
	cout << "Enter in the string you want to repeat:";
	cin >> first; // get the string
	cout << endl;


	while (second < temp)
	{
	cout << first << first << endl;
	second += 1;

	}

	return 0;
}

You need a double loop for this. Put a for-loop inside the while loop.

Well what exactly does that look like i do not understand how this will display the string mulitplying each time

Does it just have to be a while loop or can you use for loops?

[Arslan7041]

while (second < temp)
	{
         
             for(int i=1; condition; i++)
                   cout << first << " ";
            
               cout << endl; // this endl happens outside the for-loop 

               second += 1;

	}

So the first time the loop iterates twice. On the next while loop the for-loop should iterate 4 times. On the last while loop the for-loop should iterate 6 times.

So think about what 'condition' would be. You'll need to declare and initialize a variable outside the while-loop for this 'condition'. Since the iterations will go from 2 to 4 to 6, you know that the condition will have to modified every time you exit the for loop. Think about how you would modify it.
