Thread: Why my code works only in debug mode?

I wrote a c++ code using Microsoft visual c++. Now I have some weird problems

I wrote the code on computer A, and runs well.

Then I cope it to computer B. The source code can be compiled, but when I try to run it, it just stoped there, and did not show any error, and the CPU rate is 100%. However, If I open the project and press F5, the code could run in Debug mode.

Actually, I also tried to run it on computer C. There is not Microsoft c++ on it, so I coped the missing library files to the local directory, and the code runs for a while, and stopped again, just like what happend to computer B.


Can anybody give me some suggestions? why the code acts differently on different computers? and why it only runs in debug mode on computer B? This problem really drives me crazy.

Oh, I never knew that! Thanks for the enlightenment, vart!

Thank you, I solved this problem.

I used an array in my code, such as Array[i]. I initialzed the array for i= 0 to 3, but I used Array[4] by mistake. I guess in the debug mode, the Array[4] is ininitalized as 0 by compiler, but not so when you run the exe directly, and this mistake caused a endless loop in the code, and this is why the CPU rate is 100%, and the program got stuck without any error message.

I just tryed to add some print out messages for each functions, and located the mistake that I made.

There is still some other error happening to the program after running for about half and hour, I'll try to figure it out
