Concatenation

[Xerpher]

I know in VB I would use '&' to combine strings, but how exactly would I do it in C++?

AFAIK, the plus (+) operator does it nicely in C, C++, and VB.

If you are using strings from the string class, then you can just + them together.

#include <iostream>
#include <string>
 
using namespace std;
 
 
int main()
{
    string s = "Hello ";
    string t = "there!";
 
    s += t;
 
    cout << s << endl;
 
    
    return 0;
    
}

Bah! I said that! Now I get to post a useless post as well! Ha!

Yeah, the only difference is that you probably know what you are talking about when you answer questions, where as I am just a good guesser.

Not in C it doesn't

C doesn't have strings, you have NULL-terminated blocks of memory:

char first[100] = "Hello";
const char *second = " World!";

strcat(first, second);

Of course, there are far more effective ways of doing this, but it would require messing around with malloc(), etc.

Actually, there's nothing to stop you making your own string-type structure and some associated functions:

struct string_t {
    char *ptr;
    size_t allocated;
    size_t used;
};
