This is not true you could get mingw and learn c++ after you learn a command line compiler you can use any c++ compiler in fact you can use the express at the command line now. ken -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Harmony Neil Sent: Thursday, March 31, 2011 2:28 AM To: programmingblind@xxxxxxxxxxxxx Subject: RE: Simple C++/Asembler question To the original poster, what compiler are you using? Wish I could get visual studio 2010 express to work with jfw, but apparently not, so I can't even start learning c++. -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Sina Bahram Sent: 31 March 2011 07:25 To: programmingblind@xxxxxxxxxxxxx Subject: RE: Simple C++/Asembler question How are you printing? The old way of printing was to move 9 to AH, or was it AL,.. god I don't' remember. But it was an int 21 Take care, Sina -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Celia Rodriguez Sent: Thursday, March 31, 2011 2:17 AM To: programmingblind@xxxxxxxxxxxxx Subject: Simple C++/Asembler question Hi Everyone, Is there someone who can help me on this little simple problem? I am sure that my main problem is that I do not understand how the registers and storage areas work. The following is a simple console program. It adds two numbers entered by the user. and displays the answer. My problem is when the anser is > then 9 I have tried adding the two numbers to eax and displaying from eax, and moving the numbers to ah, al and adding the two numbers, all I display is garbage. I hate to bother you with this such a small problem, but I really do not understand why I cannot display what is in register eax. I will greatly appreciate anyone's help on this. Thank you, Celia // reads the first digit then clears the buffer loop10: lea ecx,b; call putstr; call getch; cmp eax,'0'; je loop10 sub eax, '0'; mov x, eax; call getch; // reads the second digit lea ecx,b; call putstr; call getch; sub eax,'0'; mov y, eax; mov ebx,x; mov ecx,y; add eax,ebx; add eax,ecx; // this part does work when adding two numbers < 10 add ecx,ebx; //cmp eax , '10'; add eax,'0'; add ecx,'0'; call putch; }0;//return 0; } __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind
