Hello World - differences between Visual Studio and NotePad++

[tarcisiocorte]

Write your question here.

// Visual Studio - It works perfectly. 
 #include <iostream>
int main()
{
	std::cout << "Hello World" << std::endl;
	return 0;
}.

// Doesn´t work into Visual Studio
#include <iostream.h>

main()
{
    cout << "Hello World!";
    return 0;
}

// Errors:
error C1083: Cannot open include file: 'iostream.h
IntelliSense: cannot open source file "iostream.h
IntelliSense: identifier "cout" is undefined

Header file iostream.h does not exist in C++, it is called iostream.

Does not exist any more. In ancient times the C++ library had header files with *.h extension, so ancient C++ compilers had them. Hence the possibility to stumble on old code samples that need porting in order to compile them.

Notepad++ is not a compiler ;)
