Functions  

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. 

Input Format

 Input will contain four integers - , 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

#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;

}
