十进制到二进制的C程序设计--递归方法加上前导零

#include <stdio.h>

void decimalToBinary(int n) {
    if (n > 1) {
        decimalToBinary(n / 2);
    }
    printf("%d", n % 2);
}

void decimalToBinaryWithLeadingZeros(int n, int numBits) {
    if (numBits > 0) {
        decimalToBinaryWithLeadingZeros(n / 2, numBits - 1);
    } else {
        return;
    }
    printf("%d", n % 2);
}

int main() {
    int decimal = 10;
    int numBits = 8;

    printf("Decimal to Binary: ");
    decimalToBinary(decimal);
    printf("\n");

    printf("Decimal to Binary with Leading Zeros: ");
    decimalToBinaryWithLeadingZeros(decimal, numBits);
    printf("\n");

    return 0;
}

Decimal to Binary: 1010
Decimal to Binary with Leading Zeros: 00001010
