Question

does this work on string in c++?

string s="lomi";
cout<<s<<endl;

what is bad in this code?

#include <iostream>
#include <cstring>
using namespace std;
int main(){

    string s=string("lomi");
    for (int i=0;i<s.length();i++){


         s[i]= s[i]+3;
    }


    std::cout<<s<<std::endl;









     return 0;
}

?

Answer 1

Yes.

(after you have #included the corresponding headers, and using the std namespace, etc.)

Edit: What’s wrong with your code is you should

#include <string>

instead of

#include <cstring>

 

 

cstring is C’s string.h header, which defines functions like strlen, strcpy, etc. that manipulates a C string, i.e. char*.

string defines C++’s string class which you’re using.
