c语言16进制数组转2进制数组的代码

以下是将16进制数组转换为2进制数组的C语言代码：

#include <stdio.h>
#include <stdlib.h>

void hexToBin(unsigned char *hexArray, int hexLength, unsigned char *binArray) {
    int i, j;
    for (i = 0; i < hexLength; i++) {
        for (j = 0; j < 8; j++) {
            binArray[i*8+j] = (hexArray[i] >> (7-j)) & 1;
        }
    }
}

int main() {
    unsigned char hexArray[] = {0x1A, 0xB3, 0x2F};
    int hexLength = sizeof(hexArray) / sizeof(hexArray[0]);
    int binLength = hexLength * 8;
    unsigned char *binArray = malloc(binLength * sizeof(unsigned char));
    
    hexToBin(hexArray, hexLength, binArray);
    
    printf("Hex Array: ");
    for (int i = 0; i < hexLength; i++) {
        printf("%02X ", hexArray[i]);
    }
    printf("\n");
    
    printf("Bin Array: ");
    for (int i = 0; i < binLength; i++) {
        printf("%d", binArray[i]);
    }
    printf("\n");
    
    free(binArray);
    return 0;
}

这个程序会将16进制数组 `{0x1A, 0xB3, 0x2F}` 转换为二进制数组 `{00011010, 10110011, 00101111}`。
