C++ String Length
String Length
To get the length of a string, use the length() function:
Example
string txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
cout << "The length of the txt
string is: " << txt.length();

Tip: You might see some C++ programs that use the size() function to get the length of a string. This is
just an alias of length(). It is completely up to you if you want to use length() or size():
Example
string txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
cout << "The length of the txt
string is: " << txt.size();
