No such file iostream.h when including

Even after naming the source file with .cpp extension. my compiler gives this error, both in command prompt and Codeblocks. How can I fix this issue?

#include <iostream.h>

int main(){

    cout<<"Hello World!\n";
    return 0;


That header doesn't exist in standard C++. It was part of some pre-1990s compilers, but it is certainly not part of C++.

Use #include <iostream> instead. And all the library classes are in the std:: namespace, for ex­am­ple std::cout.

Also, throw away any book or notes that mention the thing you said.
