C++ substr

[Nathan Poultney]

I'm having trouble finding the last 3 characters of a string.

I have the following:

string something;
    char result;
    string last3;
    
    
                something = "12345";
                result = something.length()-3;     
                last3 = something.substr(result, 0);  
   cout << last3 << endl;

I want it to output '345', but I'm getting '2'.

Any help is appreciated, thanks.

Regards,
Ace

Just substr(result).

Never mind, I figured it out.

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

int main()
{
 
 string text = "I do like the seaside";
 cout << "Original: " << text << endl;
 cout << "Last character: " << text.at( text.size() - 1 ) << endl; // returns 'e'
 
 cout << "Last 3 characters: " << text.substr( text.size() - 3 ) << endl; // returns 'ide'
 
 system("pause");
 return 0;   
}
