Create An Array Of Number In C++

Learning to create an array of numbers in C++ is important for those wanting to dive deeper into data management within their programs. This article will provide you with a concise guide on how to proceed with this task.

Code snippet: Creating an Array in C++

Here is a simple code snippet that demonstrates how to create an array of numbers in C++:

#include<iostream>
using namespace std;

int main() {
    int numbers[5] = {1, 2, 3, 4, 5};
   
    for(int i=0; i<5; i++){
       cout << numbers[i] << endl;
    }
    return 0;
}

Code Explanation: Creating an Array in C++

Let’s look at the code step by step and understand what’s going on exactly.

1. #include<iostream>: This is the preprocessor directive used to include the contents of iostream file in the program. iostream is a file that contains codes of the predefined objects used for standard I/O operations.

2. using namespace std;: The namespace std is used to call out the functions that are defined within the scope of std.

3. int main(): This is the beginning of the main function which is the entry point of any C++ program.

4. int numbers[5] = {1, 2, 3, 4, 5};: This creates an array of integers. The array is named ‘numbers’ and has a size of 5. It contains five elements in which are respectively 1, 2, 3, 4, and 5.

5. The loop for(int i=0; i<5; i++){cout << numbers[i] << endl;} is used to iterate through the array. In each iteration, we output the corresponding numbers[i]. The endl is used to insert a new line after each output to format the display.

6. return 0;: This statement terminates the main function and returns the value 0.

Here we’ve successfully created an array and displayed its contents, giving a quick tutorial on a key facet of utilizing data in C++. Practice with different array sizes and contents for better comprehension.
