当接收到一个数字时，如何分解并输出其各个位上的数字?

当你接收一个数字并需要将其分解成各个位的数字来输出时，这通常涉及到将整数转换为字符串或者按照位操作的方式来处理。以下是几种常见的编程语言中实现这个功能的方式：

1. **Python**:

def decompose_number(num):
    return [int(digit) for digit in str(num)]

number = 12345
decomposed = decompose_number(number)
print(decomposed)

2. **Java**:

public int[] decomposeNumber(int num) {
    String strNum = Integer.toString(num);
    int[] digits = new int[strNum.length()];
    for (int i = 0; i < strNum.length(); i++) {
        digits[i] = Character.getNumericValue(strNum.charAt(i));
    }
    return digits;
}

int number = 12345;
int[] decomposition = decomposeNumber(number);
for (int digit : decomposition) {
    System.out.println(digit);
}

3. **JavaScript**:

function decomposeNumber(num) {
    return Array.from(String(num), Number);
}

let number = 12345;
let decomposition = decomposeNumber(number);
decomposition.forEach(digit => console.log(digit));
