AI代码解释 void*memcpy(void*memTo,constvoid*memFrom,size_t size){if((memTo==NULL)||(memFrom==NULL))//memTo和memFrom必须有效returnNULL;char*tempFrom=(char*)memFrom;//保存memFrom首地址char*tempTo=(char*)memTo;//保存memTo首地址while(size-->0)//循环size次,复制memFrom的值到memTo中*tempTo++=*tempFrom++;returnmemTo;}
strcpy和memcpy的区别 strcpy和memcpy都是标准C库函数,它们有下面的特点。 strcpy提供了字符串的复制。即strcpy只用于字符串复制,并且它不仅复制字符串内容之外,还会复制字符串的结束符。 已知strcpy函数的原型是:char* strcpy(char* dest, const char* src); memcpy提供了一般内存的复制。即memcpy对于需要复制的内容...
