string array

how do i increment a string array?
like a becomes b, x becomes y?

ex. Hello world becomes ifmmp xpsme.

An array of chars is actually an array of 1 byte numbers.
The ASCII table lists the character representations of these numbers. If you don't have that chart handy, just look for yourself:
char c = 0;
while(c < 127) {
printf("%c = %i \n", c, c);
getch();
c++;
}

So really, it's just a matter of looping through the string and incrementing the value of each char. That's basically it.

If you are using the STL, you can do it with std::string and the transform algorithm:

Code:

---

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

class IncrementString {
public:

    inline char operator()(char c){ return ++c; }

};

int main()
{
    string str("Hello World");

    cout<<"String before transform: "<<str<<endl;

    transform(str.begin(), str.end(), str.begin(), IncrementString());

    cout<<"String after transform: "<<str<<endl;
 
    return 0;
}

how about any word inputted in the c++ program? just any other word becomes all the letters in the word incremented
