Showing errors wid iostream

Question

I installed code blocks in ma PC and tried to run the hello world programme, but the compiler is showing errors as "fatal error: iostream:no such directory" what shall I do .. help me out please

Answer 1

Please post your entire code for inspection.

Answer 2

type #include <iostream>

Answer 3

add a line below #include <iostream>
using namespace std;

Answer 4

dear try to save your file with extension .cpp instead of .c
it will help

Answer 5

type using namespace std;

Answer 6

every c++ program has using namespace std;
its so you can use the std library

Answer 7

#include <iostream> if this gives error try #include <iostream.h>

Answer 8

it allows you to use standard library containing cin cout endl etc.
if you dont use this line you can still use cin cout endl etc but you have to use prefix std:: before them i.e.
you have to write
std::cout <<"hello world"<<std::endl;

and when you use using namespace std

cout <<"hello world"<<endl;

Answer 9

iostream is a header file that provides input and output services. if you want to use cin and cout you must have it
and namespace allows you to use them without adding prefix std::
