Function Pointers in C and C++By Alex Allain A function pointer is a variable that stores the address of a function that can later be called through that function pointer. This is useful because functions encapsulate behavior. For instance, every time you need a particular behavior such as ...

In C and C++ programming, pointers are very powerful. As we explained in C pointers example article, pointers are variables that hold address of another variable so that we can do various operations on that variable. Sometimes a programmer can’t imagine
Pointers can be used to get around the “call by value” restriction. In the next example we will use pointers to correct the problem: #include<iostream> using namespace std; void swapping(int *ptr_c, int *ptr_d) { int tmp;
C++ supports null pointer, which is a constant with a value of zero defined in several standard libraries. 2 Pointer Arithmetic There are four arithmetic operators that can be used on pointers: ++, --, +, - 3 Pointers vs Arrays There is a close relationship between pointers and arrays....

constintarray_size=3;intia[array_size]={0,1,2}; If we explicitly specify a list of values, we may not specify the size of the array: the compiler itself will count the number of elements. C++ Pointer A pointer is an object containing the address of another object and allowing indirect...
