In VC debug, the running result is correct, but there is a mistake in release, and the reason is finally found.

Recently, I wrote ProgramIn the debug status, the result is completely correct, but in the release, except for the error, it took n long to find this error and finally found it. Why, that is, no initial value is assigned to the variable. In the program, there is a variable of the flaot type. In the debug state, the initial value is 0, but not necessarily in the release state. That's simple. Pain.

Therefore, in the future, it is best to assign values to variables regardless of the language, environment, or tool. Otherwise

When an error is found, it cannot be found in the north.
