Choose correct statement about Functions in C Language.a.A Function is a group of c statements which can be reused any number of timesb.Every Function don't have a return typec.Every Function may no may not return a valued.Both A & C

Which of the following statements is true about recursive functions in C?They cannot call other functionsThey can only be used with integer data typesThey call themselves directly or indirectlyThey must have a return type of void

In this challenge, you will learn simple usage of functions in C. Functions are a bunch of statements grouped 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; }+= : 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;TaskWrite a function int max_of_four(int a, int b, int c, int d) which reads four arguments and returns the greatest of them.NoteThere is not built in max function in C. Code that will be reused is often put in a separate function, e.g. int max(x, y) that returns the greater of the two values.Input FormatInput will contain four integers - , one on each line.Output FormatPrint the greatest of the four integers.Note: I/O will be automatically handled.Sample Input3465Sample Output6

Which of the following are true about function return values?Choose as many answers as you see fit.If a function does not specify a return type, the return type is Unit.A return value can be stored in a variable.Functions with a return type of Unit must include a return statement.A return value's type must match the return type of a function.

What will be the output of the following C code having void return-type function?#include <stdio.h>void foo(){return 1;}void main(){int x = 0;x = foo();printf("%d", x);}
