it will overwrite the memory beyond the end of the destination buffer. This can lead to unwanted and undefined behaviour. To prevent this, there is an updated version of memcpy() in C11 called memcpy_s. The syntax is as follows:
How memcpy() Works: Syntax and Code ExampleThe memcpy() function takes three arguments:dest: a pointer to the destination buffer location where the data is to be copied. src: a pointer to the source buffer from where the data is to be copied. n: the number of copied bytes....
It's unacceptable whenmemcpyhas overlapping source and destination regions. To handle such cases in C,memmovefunction is available. As you have been tagged C++ in this context, you may want to contemplate utilizingstd::copyinstead ofmemcpy, as the former has a less stringent constraint. In your...

well, strcpy differs from memcpy in that it stops copy at \0 the format specifier is a string.. which can be assigned to a char*.. like.. strcpy(a,&qu
