Coding Question not on Google
Alrighty, im trying to make a game using Health bars that are illustraed by the following
"Health: |||||||||||||||||"
and i wanted to know if p1Health was my int variable (int p1Health; ) representing player 1's health, how i can make that output the same number of "|"s. So if p1Health = 20, i want the code to output "||||||||||||||||||||".
(I know i could use an 'if' statement or a 'switch:case' but i would like to do it with the least amount of code possible because there is alot more elements to this game, and i don't want the health bar to take up 1000 lines. (there are two players in this game, so the shorter the code the better)
Is there a way i can use my variable p1Health and put it into setw()?
*because setw(p1Health) didnt work.

Code:
string HealthBar(unsigned int health){
string output;
for (unsigned int i = 0; i < health; ++i){
output += '|';
}
return output;
}

Code:
#include <string>
#include <iostream>
int main()
{
int p1Health = 10;
std::string strHealth(p1Health, '|');
std::cout << strHealth;
}

No need for a function -- one of the std::string constructors does this already.

Oh, I knew wxString did that, wasn't sure if std::string did. Oh well, yeah, use that.
