Adding two numbers with MASM32 ?

[deeR44]

How would I include a 'zip' file in a post?

[hutch--]

Zip the file THEN post it.

[deeR44]

That sounds easy enough. Thank you--I'll try it tomorrow.

So now do it where you get those numbers from the user (via text input). How would you do that?

Here is the program that inputs two integers, adds them together, and displays the result.
This time it's in 'zip' format and lines will line up nicely.

[hutch--]

I downloaded it and built it but I don't know what input it requires. If I run the exe by itself, nothing happens, tried two numbers on the command line but itt does nothing, how do I input any numbers to it ?

While waiting, here is a simple 32 bit example of getting user input, converting it to DWORD integers, adding the two together then converting it back to string to display.

I ran the program and got this result:

C:\masm32\projects\AddTwoInts>addtwointegers

Type your number:  1234

***1234***

Number of input digits is: 4.

Type your number:      000016

***16***

Number of input digits is: 2.

Result: 1250

C:\masm32\projects\AddTwoInts>

The second number was preceded by spaces and a tab, then leading ASCII zeros, the number and, finally, some more spaces and tabs. The program eliminates this garbage.

Does your program include this stuff except the obvious that doesn't belong"

I loaded the 'zip' from my original post, extracted it, assembled it, and finally ran it producing the above result.

[hutch--]

I downloaded the zip file, unzipped it, built it as a default console app and it built correctly. When I ran it nothing was displayed at the console. It did not respond to command line arguments so I don't know how to get any output from it.

It wasn't written to accept command line arguments as you can see in the source.
I have no idea why it doesn't run on your system. During development, I assembled this program and ran it
dozens of times. Sometimes with horrific results. But I always got some input questions.   Which are:
"Type your number:  ".

[NoCforMe]

Your program worked for me. A mystery why Hutch can't seem to get it to run. Not a great program, but it does work.

[hutch--]

OK, I got it to work, it helps if you zip the exe file with it and how to use it.


K:\add2>addtwointegers

Type your number:  160

***160***

Number of input digits is: 3.

Type your number:  140

***140***

Number of input digits is: 3.

Result: 300

Here is the program that inputs two integers, adds them together, and displays the result.

Congrats, your first working MASM program

[NoCforMe]

OK, if that really is your first MASM program, then mazeltov. It's a good feeling, no?

Hi to all! answer is near the topic
ProcEntry   PROCESSENTRY32 < 296, 0 >
how correct fill structure in data ?

align good idea when you multiple times use string to compare or big table of data
