std::string
supports iterators, and so you can use a ranged based loop to iterate through each character:
std::string str = "Hello World!";
for (auto c : str) {
std::cout << c;
}
You can use a “traditional” for
loop to loop through every character:
std::string str = "Hello World!";
for (std::size_t i = 0; i < str.length(); ++i) {
std::cout << str[i];
}
