The strcpy() function accepts a pointer, array, or an explicit string as an input argument to “s2”. The data type of the buffers that are used in its input and output arguments must be the pointers or arrays of elements of type char or unsigned char. When using the strcpy() function...
//allocate memory and set up pointers for statelist char**statelist; statelist =malloc((MAX_REPETITION_PERIOD+1) *sizeof(char*) + (MAX_REPETITION_PERIOD+1+1) * nrows * ncols);//MAXREP+1 is the number of strings we want to store. The other +1 is to fit in the null temrinator...
I'm working with structures in C for the first time and I hate to admit that I don't think I'm understanding it very well. I'm trying to build an array of pointers that point to Student structures to ... WiFi 的起源、发展、信道划分及网络结构解析 ...

The underlying type of the objects pointed by both thesourceanddestinationpointers are irrelevant for this function; The result is a binary copy of the data. The function does not check for any terminating null character insource- it always copies exactlynumbytes. ...
If you have to use strcpy, you can supress the warning using _CRT_SECURE_NO_WARNINGS - again, see the documentation.There is another warning shown by MS visual c++ runtime library , saying that: Debug assertion failed! Expression: (L"Buffer is too small"&&0).Do...
Concatenating with std::string is a simple task, although the challenge arises when transferring the data to extStr without employing strcpy. Unfortunately, using string:: c_str() function results in a pointer to non-modifiable data, thus setting extStr equal to it is not possible. A...
