Functions in C - Hacker Rank Solution
Problem
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 7 | 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
1 2 3 4 5 6 7 8 | 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; } |
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.
Note: I/O will be automatically handled.
Sample Input
3 4 6 5
Sample Output
6

Hey, I am Parthe Omkar
i was searching for this answer and i got here thank you so much it helped a lot
still 2 test case failed
int max(int a, int b) {
if (a > b) {
return a;
return b;
}
in the main function
return max(max(max(c, d), b), a);
