Implementing associative arrays in C/C++

This article demonstrates using string/char* indexes in regular C array, e.g. myArray["age"]=10;

We usually use numaric indexes in arrays with C and C++. But there can be another way of using C / C++ arrays like in PHP, e.g.

//create arrays
Array <std::string> info; //create array of string
Array <float> extra; //create array of float

//add data 
info["name"]    = "John";
info["title"]   = "RAD C++ Programmer";

extra["age"]     = 29;
extra["salary"] = 5000;

//use/display the data
cout << info["name"] << " earns $" << extra["salary"];

Isn’t it great ? I hope you would say offcourse!

To do this we will be using C++ tempaltes programming.

Now what you have to do is, download the header file called ctia.h here and include in your program. Better is put it in your compiler’s include folder. I will not be forcing you to learn templates programming first, but just you a GO to use my premade class.

A sample program would be:

#include <ctia.h>

int main() {

  Array <std::string> info;

  Array <float> extra;

  info["name"]    = "John";
  info["title"]   = "RAD C++ Programmer";

  extra["age"]     = 29;
  extra["salary"] = 5000;

  cout << info["name"] << " earns $" << extra["salary"];

  system("PAUSE");

  return EXIT_SUCCESS;
}
