Question

(In C++) The program will output a right triangle based on user specified height triangleHeight and symbol triangleChar.

Modify the program to use a nested loop to output a right triangle of height triangleHeight. The 1st line will have one user-specified character, such as %or * Each subsequent line will have 1 additional user-specified character until the number in the triangle"s base reaches triangleHeight. Output a space after each user-specified character, including after the line"s last user-specified character.

Example output for triangkeChar=% and triangleHeight=5:

This program will output a right triangle based on user specified height triangleHeight and synbol triangleChar.

The given program outputs a fixed-height triangle using a * character. Modify the given program to output a right triangle that instead uses the user- specified triangleChar character.

Answer 1

If you have any doubts, please give me comment...

#include<iostream>

using namespace std;

int main(){

int triangleHeight;

char triangleChar;

cout<<"Enter triangle height: ";

cin>>triangleHeight;

cout<<"Enter triangle character: ";

cin>>triangleChar;

for(int i=0; i<triangleHeight; i++){

for(int j=0; j<=i; j++){

cout<<triangleChar;

}

cout<<endl;

}

return 0;

}
