1. Use the code tag.
2. Change ln.length() to str.length() Because you want to get the length of the string str. Not the string ln.

#include<iostream>
#include<string>
using namespace std;

int main() {
// use string variable to write a sentence
string str;
cout << " please enter your full name: ";
getline (cin,str);
cout << " The sentence typed was: " << str << ".\n";
string ln (" ");
cout << " the length of your name is: " << str.length() << " charactares.\n:";
return 0;
}
