Answer to Question #545 in C++ for Chu-Hua

Question

I am developing a program for calculating the integral function. Why everything is good in the debug build, but the result is wrong in the release?

Answer 1

Perhaps you have uninitialized variables. In some compilers in the debug build all the variables are initialized to zero, and all pointers – to a NULL pointer, which is not done in the release in order to optimize the execution time.
