How to assign values to an integer array in C language?

There are multiple ways to assign values to an int array, here are two common methods:

1. Assign values one by one using a loop.

int arr[5];
for (int i = 0; i < 5; i++) {
    arr[i] = i + 1;  // 为数组元素赋值
}

1. Use static initialization:

int arr[] = {1, 2, 3, 4, 5};  // 直接在定义数组时赋值

Both of the methods can be used to assign values to an integer array, depending on the specific situation.
