An entry point, usually main().
Every C plus plus program that is a main program must have the function 'main'.
Every C++ program must have a main() function that returns an integer:int main(){// user-code goes here....// Main must return an integer to the calling program.// A non-zero value usually indicates an error occurred but// the exact meaning of the return value is user-defined.return( 0 );}
All C++ programs require an entry point and the main function provides that entry point.
I don't think its possible. Every C++ program must at least have the main function.
one will contain a minus sign and the other will contain a plus sign
Whoever said so, they were wrong. For sure "printf" can be used without any problem.
It must be done by a platform-dependent function, it's "clrscr" from conio.h in TurboC

C++ programs won't compile if they contain compiler errors. The compiler will tell you precisely where the error is, and the type of error, unless the error is in a macro. The compiler cannot see macro definitions because they are inline expanded prior to compilation.
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.
to define an additional task to an operator ,we must specify what it means in relation to the class to which the operator is applied.this is done with the help of a special function called operator function ,which describes the task.
Writing programs in it.
