hey guys im trying to make a program that will encrypt text. my first step is to alter the text.
for example, if i have "hello" as key, im trying to make it "ifmmp"... like every character should add 1. but it's not working for some reason. any idea wht might be wrong with it?
code:

int encrypt(string key){

    for (int i =0;i<key.length();i++){
        char temp = key.at(i)+1;
        string me = temp;
        key.replace(i,1,me);
    }
    cout <<key << endl;

   //more stuff goes here
}

Moved to help (not a tutorial). Also, you've been here for long enough to know that "it's not working for some reason" is not a valid question. In which way does it "not work"?

I'm guess you're problem is trying to assign the char temp to the string me. You can't convert a character to a string like that. They are different data types. Try using sprintf to create a formatted string and to copy that formatted string into 'me'.

code:
sprintf(me, "%c", temp);


EDIT:
My bad. My knowledge of C is limited to working with primitive types. When I read string me = temp my brain said char me[80] = temp. Anyway, glad you figured it out.
