一维黎曼问题的欧拉求解，.exe无法运行，请关闭程序？

ligenFortran · 发表于 2019-8-19 19:23:52

一维黎曼问题的欧拉求解代码，利用MacCormack格式计算，最后输出原始变量密度、压力、速度。我自己编写后，利用gfortran编译(code-block集成环境)，弹出一个串口：
出现了一个问题，导致MacCormack_1D_Rimenn.exe无法运行，请关闭程序
请问这是咋回事？是写的代码有问题？还是软件存在问题啊，我截了图，希望大神帮我解答！感谢感谢感感谢！

你数数，函数参数个数都不一样，能运行才怪了。

你用的什么编译器？这种基础的问题都不能自动检查出来。赶快乘没人看见的时候，卸载了换一个。

你数数 ...

我用的gfortran编译器，编译没有错误。谢谢您一语道破，我把参数修改了之后依然弹出来exe错误运行的窗口，不懂咋回事
