C malloc Function - Learn about the C malloc function, its syntax, usage, and how to dynamically allocate memory in C programming.
malloc is a standard library function in C and C++ that is used to allocate memory dynamically. It takes a single argument, which is the size of the memory block to be allocated in bytes. The function returns a void pointer to the allocated memory block, or NULL if the allocation fails....
