return array of string in function c++

To return an array of strings from a function in C++, you can follow these steps:

  1. Define the function with the return type as an array of strings. You can use the std::array or std::vector container classes to represent the array. For example, to use std::array, you can declare the function as follows:

cpp std::array<std::string, N> functionName()

Here, N represents the size of the array.

  1. Create an array of strings inside the function. You can use the std::array or std::vector constructors to initialize the array with the desired strings. For example, to create an array of three strings, you can use the following code:

cpp std::array<std::string, 3> myArray = { "string1", "string2", "string3" };

Alternatively, you can create an empty array and populate it with strings using the push_back or emplace_back functions of std::vector. For example:

cpp std::vector<std::string> myArray; myArray.push_back("string1"); myArray.push_back("string2"); myArray.push_back("string3");

  1. Return the array from the function. If you are using std::array, you can simply use the return statement followed by the array name. If you are using std::vector, you can return it by value. For example:

cpp return myArray;

  1. In the calling code, you can capture the returned array by assigning it to a variable of the same type. For example:

cpp std::array<std::string, 3> result = functionName();

or

cpp std::vector<std::string> result = functionName();

Now, the result variable will hold the array of strings returned from the function.

That's it! You have successfully returned an array of strings from a function in C++.
