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 nothing (void) or something.

The 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 return the sum of four parameters 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;
}

Write a function int max_of_four(int a, int b, int c, int d) which returns the maximum of the four argument it receives.

+= : 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, on one per line.

Output Format

Return the greatest of the four integers.

PS: I/O will be automatically handled.

Solution - Functions in C++ - Hacker Rank Solution

#include <iostream>
#include <cstdio>
using namespace std;

/*
Add `int max_of_four(int a, int b, int c, int d)` here.
*/
int max_of_four( int a, int b, int c, int d){
    if ( a > b && a > c & a > d) return a;
    else if ( b > a && b > c && b > d) return b;
    else if ( c > a && c > b && c > d) return c;
    else return d;
}

int main() {
    int a, b, c, d;
    scanf("%d %d %d %d", &a, &b, &c, &d);
    int ans = max_of_four(a, b, c, d);
    printf("%d", ans);
    
    return 0;
}
