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

#include
using namespace std;
int max_of_four(int a,int b,int c,int d)
{
int max = 0;
if(a>=b && a>=c && a>=d)
{
max = a;
}
else if(b>=a && b>=c && b>=d)
{
max = b;
}
else if(c>=a && c>=b && c>=d)
{
max = c;
}
else
{
max = d;
}
return max;
}
int main() {
int a, b, c, d;
cin>>a>>b>>c>>d;
int ans = max_of_four(a, b, c, d);
cout<<ans;
return 0;
}
