With this current C++ code how can I get ride of this highlighted comma after my last value.

#include

#include

using namespace std;

int main() {

int result,num,i=1;

int userValue;

int minValue = 3;

int maxValue = 100;

cout << "Please enter a number from 3 to 100: ";

cin >> userValue;

cout << userValue;

if(userValue < minValue || userValue > maxValue){

cout << "Please follow the directions!" << userValue << endl;

}

else {

cout << endl;

while(result

result = pow(2,i);

if(result

num=result;

cout << result << ", ";

}

i++;

}

cout << " The answer is " << num << endl;

}

return 0;

}
