C++ Array of Strings

**ScoutDavid** · 03-26-2011

I have a question, a newbie question, though:

I need to create an array of strings like this:

Code:

groupBits7 = ['10','11','12','13','14','15','16','17','18','19','1A','1B','1C','1D','1E','1F']

That is python, I need to make something similar in C++, and that allows me to access it like array[2].

Thanks.

Code:

char groupBits7[] = { '10','11','12','13','14','15','16','17','18','19','1A','1B','1C','1D','1E','1F' };

Careful that you do not access out of bounds.

That should be:

Code:

const char *groupBits7[] = { "item1", "item2", "item3" };

Thinking about it... of course, that was my mistake. I would do it this way:

Code:

std::string groupBits7[] = { "10","11","12","13","14","15","16","17","18","19","1A","1B","1C","1D","1E","1F" };

@Elysia
You surprised me. An array?

How about:

Code:

std::vector<std::string> groupBits7 = { "10","11","12","13","14","15","16","17","18","19","1A","1B","1C","1D","1E","1F" };

If you want to go that route, then:

Code:

std::array<std::string> groupBits7 = { "10","11","12","13","14","15","16","17","18","19","1A","1B","1C","1D","1E","1F" };

However, this requires initialization lists which is only available in GCC.

This is what I like the most

I have another question, how to use more than one function? Ok, I'm not that dumb:

Code:

#include <iostream>

using namespace std;

int main() {
  cout << "Hello World";
  cout << sum2Numbers(10,200); //Will return 210
  cin.get();
  return 0;
}
int sum2Numbers(int a, int b) {
  return a+b;
}

My question is, how do I declare the second function? I know I have to do that, but can't remember why and how.

EDIT Never mind, I got around it.
