How to Convert a C++ String to Uppercase

Question

I need to convert a string in C++ to full upper case. I\'ve been searching for a while and found one way to do it:

#include 
#include 

        

Answer 1

You could do:

string name = "john doe"; //or just get string from user...
for(int i = 0; i < name.size(); i++) {
    name.at(i) = toupper(name.at(i));
}
