[SOLVED] What's happened with my cout<< ?
-
Hello Qt World !
Is there somebody can explane at me why the display is different ? It's very strange !
@#include <iostream>int add(int & a)
{
a += 1;
return a;
}void enUneLigne();
void enPlusieursLignes();int main()
{
std::cout << "en une ligne:" << std::endl;
enUneLigne();
std::cout << std::endl << std::endl << "en plusieurs lignes:" << std::endl;
enPlusieursLignes();
return 0;
}void enUneLigne()
{
int a(0);std::cout << "1: " << add(a) << std::endl << "2: " << add(a) << std::endl << "3: " << add(a) << std::endl << "4: " << add(a) << std::endl;}
void enPlusieursLignes()
{
int a(0);std::cout << "1: " << add(a) << std::endl; std::cout << "2: " << add(a) << std::endl; std::cout << "3: " << add(a) << std::endl; std::cout << "4: " << add(a) << std::endl;}
@the display :
@Démarrage de \QT Projects_Essai4\debug_Essai4.exe...en une ligne:
1: 4
2: 3
3: 2
4: 1en plusieurs lignes:
1: 1
2: 2
3: 3
4: 4
\QT Projects_Essai4\debug_Essai4.exe a quitté avec le code 0@

This has nothing to do with Qt. the fact is just that C and C++ execute commands "from right to left" so the first function that is called in the enUneLigne() function is the one related to the fourth line of the text

thank you for your response !
Have a nice evening.
