In conclusion, the strcpy function in C is a built-in library function used to copy one string to another. It takes two parameters, the destination string and the source string. The function copies all the char
Thestrcpy_sfunction copies the contents in the address ofsrc, including the terminating null character, to the location that's specified bydest. The destination string must be large enough to hold the source string and its terminating null character. The behavior ofstrcpy_sis undefined if the so...

你这个程序是有问题的！首先，虽然传递的是地址，但是仍然是属于传值调用的范畴。因为指针只是用来赋值，并没有被间接引用。那么你是不是想用传址调用呢，就这个程序而言，也是不行的。你希望通过交换str1和str2的值来实现字符串的赋值，是行不通的。因为，在C++中，任何一个数组的名，都是一个指针...

strcpy_sis allowed to clobber the destination array from the last character written up todestszin order to improve efficiency: it may copy in multibyte blocks and then check for null bytes. The functionstrcpy_sis similar to the BSD functionstrlcpy, except that ...
In C++, these functions have template overloads that invoke the newer, secure counterparts of these functions. For more information, seeSecure template overloads. By default, this function's global state is scoped to the application. To change this behavior, seeGlobal state in the CRT. ...
