print array elements with space c++

To print array elements with spaces in C++, you can use a loop to iterate through each element of the array and print it followed by a space. Here's an example:

#include <iostream>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);

    for (int i = 0; i < size; i++) {
        std::cout << arr[i] << " ";
    }

    return 0;
}

Explanation:

1. We include the <iostream> header file to use the std::cout object, which is used for standard output.
2. We declare an array arr and initialize it with some elements.
3. We calculate the size of the array by dividing the total size of the array by the size of one element. This gives us the number of elements in the array.
4. We use a for loop to iterate through each element of the array.
5. Inside the loop, we print each element using std::cout followed by a space.
6. Finally, we return 0 to indicate successful execution of the program.

This code will output: 1 2 3 4 5. Each element of the array is printed followed by a space.
