Functions in C++ - Hacker Rank Solution
Problem
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 :
return_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
int sum_of_four(int a, int b, int c, int d) { int sum = 0; sum += a; sum += b; sum += c; sum += d; return sum; }
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.
PS: I/O will be automatically handled.
Sample Input
3 4 6 5
Sample Output
6
