The syntax for declaring a pointer in C is as follows: data_type *name_of_the_pointer; Here, data_type is the type of data the pointer is pointing to. The asterisk sign (*) is called the indirection or dereferencing operator. It serves as a pointer’s representation. It informs the...

Ensuring that the destination buffer has an adequate size to hold the copied data. Checking the amount of data being copied to ensure it does not exceed the capacity of the buffer. Avoiding the use ofstrcpywith non-string data types, since it can result in undefined behavior and potential se...
The problem is that it is not syntaxically correct to use the return value of a function that returnsvoid. Should I have duplicated the already huge amount of code duplication: once for the void return type and the other for the non-void? No, thanks to the comma operator. ...
