#include <stdio.h>

int main() {
  printf("hello wordl\n");
}

<stdudio.h> contains a typo

<conio.h> does not exists on Linux. It is not a C or C++ Standard
header file. Furthermore, I doubt that it is necessary at all for
building that program with your Windows compiler.

And now build the program with

g++ myprogram.cpp -o myprogram

Note that you should use 'g++' instead of 'gcc' for building C++
apps. g++ automatically uses some libraries that are often required
for building C++ apps.

It will generate an executable called "myprogram". If "-o myprogram"
were absent it will generate an executable named 'a.out'. It's a valid
executable, despite it's name. Execute your program with

./myprogram

note the ./ It's necessary because, out of the box, most shells does
not looks for executables on the current directory, so you need to say
"execute the 'myprogram' executable which is located on the current
directory"

Hope this helps.

Now execute the command 

info g++

and enjoy the fine manual :-)
