Yea sweet lets start off learning c++ by having the user guess what arbitrary number of spaces are required to pass the specs


Is is necessary to write std:: ?

I’ve been waiting for quite some time for this C++ course to come out, and i really like it! The only thing that i think is weird is that i can t see what it says it wants me to make it say, so then i have to see the solution, when i want to keep trying.


You can type:

using namespace std;

at the beginning of your program to not have to type std:: every time in your program.


Hi can someone pls tell me what I am doing wrong? I pass the exercise but on the right side it isn’t the same pattern.


int main()


int main()

std::cout << " 1\n";
std::cout << " 2 3\n";
std::cout << " 4 5 6\n";
std::cout << “7 8 9 10\n”;



Should be like this.
