Get wrong answer in code::Blocks for C programm

Hi
I've been started to learn C program with code::blocks
I downloaded this version (codeblocks-20.03mingw-setup) from the site

Now when I just write a simple code for sum two digit, I get wrong result,
for example : 3+5 get 16 for answer
I put the screen from the operation and run and result

Please someone help me
I don't know what to do :(

It should be
scanf("%d", &a);
not
scanf("%d, &a");

You got the end " in the wrong place.

The compiler should have warned you.

Thank you :):o
