Question

#include <iostream>
using namespace std;

void drawTriangle(int w) {}

int main() {}

Complete the program so that it produces a centered, isosceles triangle of a user-specified width.

For example:

Enter a width: 5

Result:

*****
 ***
  *

Answer 1

#include <iostream>
using namespace std;

void drawTriangle(int w) {
   int n = 5, s = 0;
   for(int i = 0;n>0;i++){
      for(int k = 0;k<s;k++){
         cout<<" ";
      }
      for(int j = 0;j<n;j++){
         cout<<"*";
      }
      cout<<endl;
      n -= 2;
      s += 1;
   }
}

int main() {
   int w;
   cout<<"Enter a width: ";
   cin>>w;

   drawTriangle(w);

   return 0;
}
