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);}
Question
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);}
Solution
The code you provided will not compile successfully. In C, a function with a void return type is not allowed to return a value. In your code, the function foo() is declared as void but is trying to return an integer value (1). This will cause a compilation error.
If you want foo() to return an integer, you should declare it as int foo(). Here's how you can correct your code:
#include <stdio.h>
int foo(){
return 1;
}
void main(){
int x = 0;
x = foo();
printf("%d", x);
}
In this corrected version, foo() is declared to return an integer, and it returns 1. This value is then assigned to x in the main() function, and x is printed out. So, the output of this corrected program will be 1.

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
