How to Initialize an Array in C ?

Answer

To initialize an array in C, you can use array literals.

✐ Examples

1 Initialize Integer Array

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 <stdio.h>

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

Output

1 2 3 4 5

2 Initialize Character Array

In this example,

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

C Program

#include <stdio.h>

int main() {
    char fruits[] = {'A', 'p', 'p', 'l', 'e'};
    for (int i = 0; i < sizeof(fruits) / sizeof(fruits[0]); i++) {
        printf("%c ", fruits[i]);
    }
    return 0;
}

Output

A p p l e
