下面代碼分別給出了三種將二進制字節字符轉換為ASCII的方法

/* * @brief 該函數實現了將二進制字節數據轉換為可打印ASCII碼字符串 * @param[in] pSrc 源數據指針 * @param[in] nSrcLength 源數據長度 * @param[out] pDst 目標字符串指針 * @return 目標字符串長度 */#include <assert.h> #include <iostream> using namespace std;int BinaryBytes2String1(const unsigned char *pSrc, unsigned int nSrcLength, char *pDst) {if(pSrc == 0 || pDst == 0)return 0;char *p = pDst;for (unsigned i=0; i<nSrcLength; i++) {*p = (pSrc[i] >> 4) & 0x0f;*p += *p < 10 ? 0x30 : (0x61 - 10);p++;*p = pSrc[i] & 0x0f;*p += *p < 10 ? 0x30 : (0x61 - 10);p++;*p = pSrc[i] & 0x0f;*p += *p < 10 ? 0x30 : (0x61 - 10);p++;}*p = '/0';return nSrcLength * 2; }int BinaryBytes2String2(const unsigned char *pSrc, unsigned int nSrcLength, char *pDst) {if (pSrc == 0 || pDst == 0)return 0;const char tab[] = "0123456789abcdef";for (int i=0; i<nSrcLength; i++) {*pDst++ = tab[*pSrc >> 4];*pDst++ = tab[*pSrc & 0x0f];pSrc++;}*pDst = '/0';return nSrcLength * 2; }int BinaryBytes2String3(const unsigned char *pSrc, int nSrcLength, char *pDst) {if (pSrc == 0 || pDst == 0)return 0;for (int i=0; i<nSrcLength; i++) {sprintf(pDst, "%02x", *pSrc);pDst++;pDst++;pSrc++;}*pDst = '/0';return nSrcLength * 2; }void main(void) {unsigned char test[3] = {0x23, 0xa4, 0xB7};char result[7];memset(result, 0, 7);BinaryBytes2String1(test, 3, result);cout << result << endl;BinaryBytes2String2(test, 3, result);cout << result << endl;BinaryBytes2String3(test, 3, result);cout << result << endl; }

輸出結果為:

??23a4b7
? 23a4b7
? 23a4b7
