在不同操作系统上输出程序的问题 [英] problem with output of the program on different OS
问题描述
我有一个我在Windows机器上创建的C程序。我编译了
并在Windows机器上执行了程序，每次运行它时它都会给我
一致的输出。例如。
输入a = 2，b = 3
假设要执行求和操作，然后：
输出：5
关于输入，输出始终一致且正确。
我尝试过在我的linux机器上运行程序。该程序编译
并执行，但我得到了奇怪的结果。例如。对于问题
以上加：
输入a = 2 b = 3
输出：1
i再次执行程序：
输入a = 2 b = 3
输出：6
又一次：
输入a = 2 b = 3
输出0
I have a C program which I created on Windows machine. I have compiled
and executed the program on windows machine and it gives me the
consistent output every time i run it. for eg.
input a = 2, b =3
lets say a sum operation is to be performed, then:
output: 5
The output is always consistent and correct with regards to input.
I tried to run the program on my linux machine. The program compiles
and executes but I''m getting strange results. For eg. for the problem
of addition above:
input a = 2 b = 3
output: 1
i execute the program again:
input a = 2 b = 3
output: 6
and again:
input a = 2 b= 3
output 0
What is happening ?

未定义行为的典型案例。如需更详细的诊断，请
提供源代码。

代码为650行，分为多个模块。我不介意
张贴它但是大多数人会怨恨它。
你认为使用非标准的问题会产生这样的问题吗？ />
编译器如PellesC？
The code is 650 lines and it is divided in many modules. I don''t mind
posting it but most people will resent it.
Do yout think problems like this one can arise by using non standard
compilers like PellesC ?

更可能是代码中的未定义行为依赖于原始编译器的
行为。
尝试并提炼一个证明问题的简短例子。

Ian Collins。
More likely undefined behaviour in the code that relies on the
behaviour of the original compiler.
Try and distill a short example that demonstrates the problem.
