Answer / inderchauhan
A pointer is a special kind of variable in C and C++ that
holds the address of another variable.
my first pointer
#include <iostream>
using namespace std;
int main ()
{
int firstvalue, secondvalue;
int * mypointer;
mypointer = &firstvalue;
*mypointer = 10;
mypointer = &secondvalue;
*mypointer = 20;
cout << "firstvalue is " << firstvalue << endl;
cout << "secondvalue is " << secondvalue << endl;
return 0;
}
firstvalue is 10
secondvalue is 20

Answer / sanjay bhosale
function pointer is simply a pointer which holds the address of the function so we can call that function by using pointer.
It is helpful in situations where we are required to pass the function pointer as parameter to some previously defined functions.
for e.g.
in comparison method we may pass function pointer for function which will compare 2 items/objects and help to comparison method.
