Question

what is the output of the program
#include
using namespace std
void Abc (int x)

Answer 1

Answer:

lots of errors

Explanation:

#include

        ^

#include expects "FILENAME".  You included nothing.

using namespace std

                                   ^

You did not end this line with a semicolon

void Abc (int x)

               ^

This looks like you want to either declare a function/ define a function, in both cases this is an error. If it was a declaration, it needs to have a semicolon in the end. If it was a definition, it needs to have curly braces and optionally a function definition.  

Missing main

The program won't execute at all.
