Your program should contain only one ‘*’ character.

PLEASE USE LOOPS FOR THIS C++ PROGRAMMING!!!!

THIS SHOULD START WITH #include<iostream> and then using namespace std; !!!!!!!!

Answer 1

using namespace std;

#include <iostream>

#include <math.h>

void printChar( char ch, int n)

{

for (int iLoop=0; iLoop<n; iLoop++)

{

cout << ch;

}

cout << endl;

}

int main()

{

int diff=2;

int expo=0;

for (int iLoop=0; iLoop<14; iLoop++)

{

if (iLoop>=7)

{

expo = iLoop-diff;

diff +=2;

}

else

{

expo=iLoop;

}

printChar('*',pow(2,expo));

}

}
