What is Call Back Function? | Function Pointer | Pointer to a Function | Sorting | C++
In this video lecture, we have discussed the Callback Function using Function Pointer for Sorting the array element.
A callback is any executable code that is passed as an argument to other code, which is expected to call back (execute) the argument at a given time [Source : Wiki]. In simple language, If a reference of a function is passed to another function as an argument to call it, then it will be called as a Callback function.
In C++, a callback function is a function that is called through a function pointer.
