Have done both shift functions, with over-shift protection and negative values support.
That was a really interesting experience implementing this. Sometimes adding custom behavior like this can make your code look more elegant and effective. And mysterious, but it totally worth it.

Answer 2

If you really want to use the << operatpr then you need to overload it, to be abel to do what you want.. but it is a lot of work for nothing...

Answer 3

@Ahmed Here you a shift function that i made for you:)

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

string shift (string value, int pos){

return value.substr(pos, value.length() - pos);

}

int main() {

cout<< shift("ahmed",3);
return 0;

}

Answer 4

I don't understand why can't we shift in nibbles ?. << (n * 4). Here n is number of characters to be shifted. Please note same logic will not work for right shift.

Answer 5

you can't do bit-shifting on strings, as it shifts binary data, filling places with zeros.
however, you can try to overload shift operator and make a custom implementation for strings only

Answer 6

Dude I gave you the answer yesterday :)

Answer 7

@demeth iam trying to overload it but i can't . if you have time can you make it please :)

Answer 8

@ripper ya but i can't use it , The program didnot run
can you make it as a complete code please ?

Answer 9

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

int main() {

string name ="ahmed";
cout<<name.substr(3, name.length() - 3);
return 0;
}

I just tried it... it works just fine:)
