/* | ||
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 - , one in each line. | ||
Output Format | ||
Print the greatest of the four integers. | ||
PS: I/O will be automatically handled. | ||
