Calculate the biggest of four integers.
The user inputs four integers. Your program will determine the biggest of these four numbers and print out an appropriate message, specifying this biggest value.
You are required to implement and use the following functions for this task:
int bigger( int x, int y );
This function takes two integer parameters and returns the bigger of those two parameters.
void printBiggest( int a, int b, int c, int d );
The function determines the biggest of the four parameters and prints it out using an appropriate message. To determine the biggest number, it needs to use another function bigger( int x, int y )which is defined above.
