How to Prevent a program by C++ from closing right away?
before return use getch();


and dont forget to add


#include %26lt;conio.h%26gt;


at the top of the program
Reply:this works








#include %26lt;iostream.h%26gt;


#include %26lt;conio.h%26gt;





int main()


{


cout %26lt;%26lt; "Hello World!\n";


getch();


return 0;


}








getch() will wait for and input just when you press any key then program will finish
