Debug Assertion Failed！
用VS2008编译，，出错！新手，大家不吝指教啊
Program：f;\VS\Convolution_first\Debug\Convolution_first.exe
File: f:\dd\vctools\crt_bld\self_x86\crt\src\fprintf.c
Line:55
Expression:(str!=NULL)
For information on how your program can cause assertion failure,see the Visual C++ documentation on asserts.

[解决办法]
依次检查每个函数，看是在哪个函数里出现的错误
[解决办法]
单步调试，找到出错的语句，查看变量
[解决办法]
你要判断文件是否打开成功
