开发中经常需要把16进制字符串转换成整形,写了个个代码供大家参考下: #include <stdio.h> #include <string.h> //字符转换成整形 int hex2int(char c) { if ((c >= 'A') && (c <= 'Z')) { return c - 'A' + 10; } else if ((c >= 'a') && (c <= 'z')) { return c - 'a' +…

将16进制字符串值转换为 int 整型值 此例中用 "1de" 作为测试字符串,实现代码如下: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> /* * 将字符转换为数值 * */ int c2i(char ch) { // 如果是数字,则用数字的ASCII码减去48, 如果ch = '2' ,则 '2' - 48 = 2 if(i…
