Before you proceed this section, we recommend you to checkC dynamic memory allocation. Sometimes, the number of struct variables you declared may be insufficient. You may need to allocate memory during run-time. Here's how you can achieve this in C programming. Example: Dynamic memory allocatio...
In previous examples the pointers were used as addresses to the memory locations already occupied by other variables. For instance, pX=&x; results in pX pointing to the memory location occupied by x. It is possible for a pointer to contain an address that is not assigned to the other ...
