C++ Vector Initialization method 03

To initialize a C++ vector, you can use the following method:

#include <iostream>
#include <vector>

int main() {
    std::vector<int> myVector = {1, 2, 3, 4, 5};
    return 0;
}

Let's break down this code and explain each step:

  1. Include the necessary headers: The code begins by including the necessary headers, <iostream> and <vector>, which provide the functionality for input/output and vectors, respectively.

  2. Declare the main function: The main function is the entry point of the program. It is where the execution begins.

  3. Declare a vector: The line std::vector<int> myVector declares a vector named myVector that stores integers. The std::vector is a container class from the Standard Template Library (STL) that provides dynamic array-like functionality.

  4. Initialize the vector: The line myVector = {1, 2, 3, 4, 5} initializes the vector with the values {1, 2, 3, 4, 5}. This is done using the initializer list syntax, where the values are enclosed in curly braces {}.

  5. Return 0: The return 0 statement indicates that the program executed successfully.

By following these steps, you can initialize a C++ vector with a set of values using the initializer list syntax.
