| + | === Exemplu de utilizare === | ||
| + | Presupunem ca avem programul ,,poo.cpp" care contine | ||
| + | <code c++> | ||
| + | #include <iostream> | ||
| + | using namespace std; | ||
| + | int main () { | ||
| + | for (int i = 0; i < 3; i++) | ||

| + | == Etapa de compilare == | ||
| + | <code bash> | ||
| + | poo@is:/laborator g++ poo.cpp | ||
| + | poo@is:/laborator ls | ||
| + | poo.cpp a.out | ||
| + | </code> | ||
| + | Observam ca in urma compilarii am obtinut executabilul **a.out** deoarece nu i-am impus un nume, iar compilatorul i-a atribuit unul by default. Pentru a denumi sugestiv executabilul o sa folosim extensia **-o**. | ||
| + | <code bash> | ||
| + | poo@is:/laborator g++ poo.cpp -o main | ||
| + | poo@is:/laborator ls | ||
| + | poo.cpp main | ||
| + | </code> | ||
| + | == Rularea executabilului == | ||
| + | <code bash> | ||
| + | poo@is:/laborator g++ poo.cpp -o main | ||
| + | poo@is:/laborator ls | ||
| + | poo.cpp main | ||
| + | poo@is:/laborator ./main | ||
| + | Hello world of OOP! | ||
| + | Hello world of OOP! | ||
| + | Hello world of OOP! | ||
| + | poo@is:/laborator | ||
| + | </code> | ||
| + | <note important>Daca avem de compilat mai multe programe, procedam astfel: | ||
| + | |||
| + | //g++ program1.cpp program2.cpp program3.cpp program4.cpp -o main// | ||
| + | |||
| + | In cazul in care lucram cu fisiere de input/output, acestea trebuie introduse ca argumente in linia de comanda delimitate de cate un spatiu. | ||
| + | |||
| + | //./main [nume_fisier1] [nume_fisier2] [nume_fisier3]//</note> | ||
