How to Declare an Integer Array in C ?

Answer

To declare an integer array in C, you can use array notation or dynamic memory allocation.

✐ Examples

1 Declare and Initialize an Integer Array

In this example,

We declare an integer array named numbers with predefined values using array notation.
We print the array to demonstrate the initialization.

C Program

#include <stdio.h>
int main() {
    int numbers[5] = {1, 2, 3, 4, 5};
    printf("Integer Array: %d, %d, %d, %d, %d\n", numbers[0], numbers[1], numbers[2], numbers[3], numbers[4]);
    return 0;
}

Output

Integer Array: 1, 2, 3, 4, 5

2 Declare an Empty Integer Array

In this example,

We declare an empty integer array named emptyArray using dynamic memory allocation.
We print the array to demonstrate the declaration.

C Program

#include <stdio.h>
#include <stdlib.h>
int main() {
    int *emptyArray = (int*)malloc(0 * sizeof(int));
    printf("Empty Integer Array:\n");
    free(emptyArray);
    return 0;
}

Output

Empty Integer Array:
