#include <iostream>
int main() {

al compilar con:
g++ hola.cpp -o hola
o con:
gcc hola.cpp -o hola
el error es:
hola.cpp: In function `int main()':
hola.cpp:4: `cout' undeclared (first use this function)

y si utilizo iostream.h en vez de iostream (sin .h), al compilar con:
g++ hola.cpp -o hola
o con:
gcc hola.cpp -o hola
el error es:
