How to get Sub Array in C ?

Answer

To get a sub-array in C, you can use array indexing.

✐ Examples

1 Sub-array of Integer Array

In this example,

We create an integer array named numbers with some values.
We then use array indexing to get a sub-array from index 2 to index 4 (inclusive).
Finally, we print the sub-array.

C Program

#include <stdio.h>
int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    int subArray[3];
    for (int i = 0; i < 3; ++i) {
        subArray[i] = numbers[i + 2];
    }
    printf("Sub-array: [%d, %d, %d]\n", subArray[0], subArray[1], subArray[2]);
    return 0;
}

Output

Sub-array: [3, 4, 5]

2 Sub-array of Character Array

In this example,

We create a character array named characters with some values.
We then use array indexing to get a sub-array from index 2 to index 4 (inclusive).
Finally, we print the sub-array.

C Program

#include <stdio.h>
int main() {
    char characters[] = {'a', 'b', 'c', 'd', 'e'};
    char subArray[3];
    for (int i = 0; i < 3; ++i) {
        subArray[i] = characters[i + 2];
    }
    printf("Sub-array: [%c, %c, %c]\n", subArray[0], subArray[1], subArray[2]);
    return 0;
}

Output

Sub-array: [c, d, e]
