OK, so I have this program I am writing called 'GradeBook', and there is a problem that starting on int Menu1(), ' if (menuchc == "4") ', and ending
if (menuchc == "y", "Y")
{
string tmp = "start " + po;
system(tmp.c_str());
system("pause");
main();
}so, I've come to conclude that getline() is not reading correctly, and subsequently tmp is null, and so substr() is throwing out_of_bounds. can someone help please? thanks!
here's the code:
