Im stuck in the block letters c++

when I try to compile the file it says : error: ‘cout’ is not a member of ‘std’
std::cout
here is the code
//include io stream

int main() {

//In my first mounth of swimming my instructor already wanted me to go to tournaments

std::cout <<“M M \n”;

std::cout <<“MM MM \n”;

std::cout <<“MM MM \n”;

std::cout <<“M M M \n”;

std::cout <<“M M \n”;

std::cout <<“M M \n”;

std::cout <<“M M \n”;

return 0;

}

It’s because you have // include iostream as a comment instead of

#include < iostream > Without the space between the brackets.

#include <iostream>

int main(){
    std::cout <<"M M \n";
    std::cout <<"MM MM \n";
    std::cout <<"MM MM \n";
    std::cout <<"M M M \n";
    std::cout <<"M M \n";
    std::cout <<"M M \n";
    std::cout <<"M M \n";

    return 0;
}
