How to Initialize an Array in C++ ?

Answer

To initialize an array in C++, you can use array literals or the array template.

✐ Examples

1 Initialize Integer Array using Array Literals

In this example,

We declare an array named numbers with integer values using array literals.
This creates an integer array in C++.
We print the array elements.

C++ Program

#include <iostream>

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

Output

1 2 3 4 5

2 Initialize Character Array using array Template

In this example,

We declare an array named fruits with character values using the array template.
This creates a character array in C++.
We print the array elements.

C++ Program

#include <iostream>
#include <array>

int main() {
    std::array<char, 6> fruits = {'A', 'p', 'p', 'l', 'e'};
    for (char fruit : fruits) {
        std::cout << fruit << " ";
    }
    return 0;
}

Output

A p p l e
