Getting the length of a string?
Ok so I have an array of char (name[20]) and normally I would use name.size() after I’ve put something in it. But name is in a structure so I did g.name.size() (the actual structure is called golf but it’s referenced by g). But I keep getting a compiler error. What’s wrong?
size() is a method of the C++ “string” class, but a string is more than just a character array. You can use the size method of the string class as follows:
#include
using namespace std;
…
string name = “John”;
cout<<"Name is "<
An array of characters does not have a size() method.
You can, however, find the size of a null-terminated c-string the following way:
char name[20] = "John";
int i=0;
while(name[i]) i++;
cout<<"Name is "<
