[others] error in scanf #333

Open hsh-notes opened 4 years ago

hsh-notes commented 4 years ago

Hello TA. I don't know why scanf doesn't work. All header files work well. Furthermore, even at the top of the code, scanf worked well. I write the code like this picture. image image

Like the following debug console, I put scanf in the code, but the program ends right away. image

Could you tell me why? There is no error that visual studio tells me. I tried many ways such as restarting the computer, using getchar, but I still could not scan 'x'.

Please use the fflush function in order to clear the input buffer for next input in character array.

However, I defined 'x' as char type.

After a few more attempts, I found that only the first scanf was ignored. So if I write scanf twice, the program works only once. Can I write the code like this? image

it's an issue in the compiler and has nothing to do with code. from my experience, you can't fix it unless you change your compiler from MICROSOFT VS COMPILER to GCC or GNU. I think you might not know that so just use codeblocks ( it is compatible with visual studio, I tested it) and it has no issues.

Thank you very much for your detailed answer.

  1. Then should I use codeblock instead of visual studio?
  2. Then should I copy the code to Visual studio when I submit it? Or can I submit a C file made of codeblock? (I don't know well about the codeblock...)

  1. Yes codeblocks is good enough
  2. Just code in codeblocks. If it works fine just submit your .c file to icampus
