C++ Pointers to functions.
- by Andy Leman
using namespace std;
int addition (int a, int b)
{
return (a+b);
}
int subtraction (int a, int b)
{
return (a-b);
}
int operation (int x, int y, int (*functocall)(int,int))
{
int g;
g = (*functocall)(x,y);
return(g);
}
int main()
{
int m,n;
int (*minus)(int,int) = subtraction;
m = operation (7,5,addition);
n = operation (20,m,minus);
cout << n;
return 0;
}
Can anybody explain this line for me
int (*minus)(int,int) = subtraction;
Thanks a lot!
