char *strcpy(char* dest, const char *src); 用unsigned char编译会出错 U8 dest[5]; U8 src[5] = {0x01,0x02,0x03,0x04,0x05}; //加上强制转换 strcpy((char*)dest, (char*)src); 或者使用 void *memcpy(void *dest, const void *src, size_t n); memcpy(dest, src, 5);...

字符串以 ‘\0’ 作为结束标志，strlen函数返回的是在字符串中 ‘\0’ 前面出现的字符个数（不包含 ‘\0’ )。举个例子： JavaScript 复制代码 99 1 2 3 4 5 6 7 8 9 10 11 #include<string.h> #include<stdio.h> intmain(){ chararr[]="abcdef";chararr2[]={'a','b','c','d',...
unsigned char* a=new unsigned char[4]; int b=14;strcpy((LPTSTR)a,(LPCTSTR)b 你这样强行转化语法上不错。但是b不是字符串也不是地址，最后很显然会有问题。你如果改成strcpy((LPTSTR)a,(LPCTSTR)&b）会把b内容拷贝到a中，但是也很危险。

strcpy, wcscpy, _mbscpy The strcpy function copies strSource, including the terminating null character, to the location that's specified by strDestination. The behavior of strcpy is undefined if the source and destination strings overlap.

int strncmp(const char * s1, const char * s2, size_t n); 该函数的作用和strcmp()类似, 不同的是, 该函数在比较n个字符后或遇到第1个空字符时停止比较。 char *strchr(const char * s, int c); 如果s字符串中包含c字符, 该函数返回指向s字符串首位置的指针(末尾的空字符也是字符串的一部分, ...
