I need to display something that looks like:
/
-
/

I currently have the following which does not print the slashes properly.
for (int i = 1; i <= numberOfDolls; i++) {
for(int j = 1; j <= i; j++)
cout << setw(numberOfDolls) << '/' << endl;
cout << "-" << endl;
}
I was thinking of using setw() to increment the slashes. Is this possible?
You can use std::setw(.) for that purpose. The key is to have a parameter defining the shift. Here is a code implementing it. Simple modifications are possible if you want to slightly modify the image.
#include <iostream>
#include <iomanip>
int main() {
int numberOfDolls = 3;
int shift = numberOfDolls + 2;
for (int i = 1; i <= numberOfDolls; i++) {
for(int j = 0; j < i; j++) {
std::cout << std::setw(shift) << '/' << std::endl;
shift--;
}
shift++;
std::cout << std::setw(shift) << "-" << std::endl;
}
return 0;
}
However, using std::setw(.) seems like an overkill. In my opinion, better to simply add spaces, for example:
#include <iostream>
#include <iomanip>
#include <string>
int main() {
int numberOfDolls = 3;
int shift = numberOfDolls + 1;
for (int i = 1; i <= numberOfDolls; i++) {
for(int j = 0; j < i; j++) {
std::cout << std::string(shift, ' ') << '/' << std::endl;
shift--;
}
shift++;
std::cout << std::string(shift, ' ') << "-" << std::endl;
}
return 0;
}
Output

I am not sure about your doubt but you will get desired output using following:
for (int i = 1; i <= numberOfDolls; i++) {
for(int j = 1, n=numberOfDolls; j <= i; j++)
cout << setw(n--) << '/' << endl;
cout <<setw(numberOfDolls-1)<< "-" << endl;
}
