3) Do not write any dereferencing operation before initializing pointer variable with a valid memory address; this may cause run time error.Consider the following code snippetint x; int *ptr; *ptr=100; //assigning value ptr = &x; //initializing the pointer ...
Using the function pointer, we can create an illusion of polymorphism. This concept is useful where we need to runtime polymorphism. To accomplish this task we need to create a function pointer within the structure and initialize the function pointer with the corresponding function. ...
“Data” variable has the scope and life only in the function “Fun”. If you try to read the value of Data after calling the Fun() using the pointer may you will get the correct value (5), but any functions called thereafter will overwrite the stack storage allocated for Data with ...
