Functions in C – Hacker Rank Solution

Objective

In this challenge, you will learn simple usage of functions in C. Functions are a bunch of statements glued together. A function is provided with zero or more arguments, and it executes the statements on it. Based on the return type, it either returns nothing (void) or something.
A sample syntax for a function is

1 2 3 4 5 6 7return_type function_name(arg_type_1 arg_1, arg_type_2 arg_2, …) { … … … [if return_type is non void] return something of type `return_type`; }

For example, a function to read four variables and return the sum of them can be written as

1 2 3 4 5 6 7 8int sum_of_four(int a, int b, int c, int d) { int sum = 0; sum += a; sum += b; sum += c; sum += d; return sum; }

Task

You have to write a function int max_of_four(int a, int b, int c, int d) which reads four arguments and returns the greatest of them.

+= : Add and assignment operator. It adds the right operand to the left operand and assigns the result to the left operand.
a += b is equivalent to a = a + b;

Input Format

Input will contain four integers –  a,b,c,d one in each line.

Output Format

Print the greatest of the four integers.
Note: I/O will be automatically handled.


Sample Input

3
4
6
5

Sample Output

6
