Answer 1

There are NO ERRORS in your code, is it fully compliant with every revision of C++.



Contrary to one answer you received, main() does not need a return statement even though it has a non-void return type. It's just one of the many ways in which main is different from user-declared functions. It's true though that some compilers erroneously warn about this -- in such cases "return 0;" may be needed.



The program can be improved stylistically by declaring variables when they are needed, rather than at the beginning of main(), as in "int result = a - b + c;", but there are no actual errors to fix.

Answer 2

You are missing a return statement , try this code instead

#include

using namespace std;



int main ()

{

int a, b, c;

int result;



a = 5;

b = 2;

c = 3;

a = a + 4;

result = a - b + c;







cout << result;

cin.get();

return 0;

}

Answer 3

Your Code is correct. When you compile this code it give a warning "Function Main should return a value" because you given main as int return type.But this is not an error you can execute it using CTRL+F9.



You need to change main as void main() for remove the warning message.
