Answer / yj
First of all, make it clear that whenever we run any program the compiler search for the main() function to start execution...
Now,
The programming language C follows top down approach. Means the control moves from top to down. Hence in this we have to give main function above all the other lines of code...
But when you program in C++ which follows bottom up approach i.e., the control moves from bottom to up...For example, when we make a function in C++ we give its definition above main() and when we call that function in main(): as soon as the compiler encounter the "calling line"...the compiler now search for the definition of that function which is above the function main(). Now u visualise that the control is moving from bottom to up.
Hence,
"The function main() in C has to be given at the top. But in C++the function main can be at the bottom also"

Answer / vishal palan
In C the main() does not return any value by default. But in C++ the main() returns value int by default.
Again
In U can complie progm by writing main(){....}
But in C++ u have to return int main() {...return 0;}
or void main() {...}

Answer / jit
In C if we write a program like
int main()
{
static int i = 5;
if (--i){
printf("%d ", i);
main(10);
}
}
It works but not in C++

Answer / hamza
in C++, you do not need to type "return 0;" statement in a [ int main() {} ]as it will be provided automatically but not in case of C.

what is the abstract class,interface ,its difference with a programatic eg.? hi,recently i went for an interview they ask me what is abstract class ,interface and its difference I said abstract class contain abstact method ,abstract method is a method with no body.Abstract class cannot be instantiated.Abstract class is a base class it required derived class for the implementation of method. Interface is a syntactical contract that all derived class should follow it define properties ,method,events which are known as member of interface. Then They asked me what is the difference between them. I said abstract class interface 1.abstact class can implement method 1.interface cant 2.abstact class can contain constructor, 2.interface cant destructor 3.abstract class cannot support multiple 3.interface support inheritance etc Then they said some different answer I said dont no. Then they ask me when i should make abstract class for an project and when i should make interface. I said if suppose there is two class which must be having method with different logic then we sholud make abstract class. and if suppose we have two class having method .with different logic then we can make interface . Am i correct with my explaination.if not correct me .please provide me that when should we create abstract class and interface and what is difference .please help me
