C++ Code

Without chaning any code below, could anyone help me to get the second line?

Ex1)

Please enter a number from 3 to 100: 6

2, 4 (<--------This is what I need - there should be no comma at the end!)

The answer is 4

Please enter a number from 3 to 100: 100

2, 4, 8, 16, 32, 64 (<-------this is what I need - no comma at the end!)

The answer is 64

#include <iostream>
#include <string>
#include <cmath>
using namespace std;

int powerOfTwo(int num);

int main () {
int num;
int result;
int i=1;
  
cout<<"Please enter a number from 3 to 100: ";
cin>>num;
cout << num << endl;
  
if ((num < 3) || (num > 100))
cout << "Please follow the directions!" << endl;
else {
int pow;
pow = powerOfTwo(num);
cout << " The answer is ";
cout << pow;
cout << endl;
}
}
int powerOfTwo(int num) {
int N = num;
int v = 1;

while (v <= N/2)
v *= 2;

cout<<v<<","; (Somebody gave this code- but it ends up with "comma"- anybody knows who to fix it? )
return v;
}

Explanation / Answer

YOU HAVE MISSED A BRACKET WHICH I HAVE POINTED IN THE CODE BELOW.

NEVER EVER MISS BRACKETS, IT BECOMES DIFFICULT TO UNDERSTAND BLOCKS.

ALSO FIXED THE "," PART.

#include <iostream>
#include <string>
#include <cmath>
using namespace std;
int powerOfTwo(int num);
int main () {
int num;
int result;
int i=1;

cout<<"Please enter a number from 3 to 100: ";
cin>>num;
cout << " You have entered "<<num << endl;

if ((num < 3) || (num > 100))
cout << "Please follow the directions!" << endl;
else {
int pow;
pow = powerOfTwo(num);
cout << " The answer is ";
cout << pow;
cout << endl;
}
}
int powerOfTwo(int num) {
int N = num;
int v = 1;
while (v <= N/2){ //you missed this bracket
v *= 2;
cout<<v<<",";
} //you missed this bracket
cout<<" "<<endl;   //this will do the trick
return v;
}
