Well, your example is neither valid C-code, nor valid C++-code:
- iostream belongs to C++, and not c
- printf is declared in stdio.h, for C
- you should use #include <iostream> instead of "iostream". With "", gcc
searches only in the current directory (and in all directories given given as
include directories on command line)
- the filename should end on ".c" instead of ".cpp". ".cpp" is understood as
C++-code by gcc
- If you see nothing in the output: add a newlin "\n" to the printf-command
- If you compile using "gcc", the compiler does not link to the C++-libraries.
use "g++" instead.
If you use (C-version, ola.c)
#include <stdio.h>
int main(){
printf("olare\n");
return 0;
}
it should work with gcc ola.c -o ola.exe. This also works with
g++ ola.c -o ola.exe
or as
gc ola.cpp -o ola.exe
if you want
As C++ version, I would propose (in ola.cpp):
#include <iostream>
int main(){
std::cout << "olare" << std::endl;
}
with
g++ ola.cpp -o ola.exe
The "best" programming environment depends on what you like - I'm using vim
