printing out an array in c from user input

Here is an example of how you can print out an array in C from user input:

#include <stdio.h>

int main() {
    int size;
    printf("Enter the size of the array: ");
    scanf("%d", &size);

    int arr[size];
    printf("Enter the elements of the array:\n");
    for (int i = 0; i < size; i++) {
        scanf("%d", &arr[i]);
    }

    printf("The array elements are: ");
    for (int i = 0; i < size; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}

Explanation:

First, we include the stdio.h library, which provides functions for input and output operations.
The main() function is the entry point of the program.
We declare a variable size to store the size of the array.
We use printf to ask the user to enter the size of the array.
We use scanf to read the user's input and store it in the size variable.
We declare an array arr of size size to store the elements entered by the user.
We use printf to ask the user to enter the elements of the array.
We use a for loop to iterate size times and use scanf to read each element entered by the user and store it in the corresponding index of the arr array.
We use printf to print "The array elements are: ".
We use another for loop to iterate size times and use printf to print each element of the arr array.
Finally, we return 0 to indicate successful execution of the program.
