If that condition is not true, the assertion fails, execution of your program is interrupted, and the Assertion Failed dialog box appears.Visual C++ supports assertion statements that are based on the following constructs: MFC assertions for MFC programs. ATLASSERT for programs that use ATL. CRT assertions for programs that use the C run-time library.The ANSI assert function for other C/C++ programs.You can use assertions to catch logic errors, check results of an operation, and Test error conditions that should have been handled.

Since I have gotten this error a number of times .. I assume there is a flaw in the way I'm using http://stackoverflow.com/questions/8709320/debug-assertion-failed-while-using-fscanf fscanf. I would appreciate it if someone could tell me the usage or .. give me a demo sample code that illustrates the simple usage .. ! I tried looking up the error .. in most places it said I haven't closed the file .. but I have and I'm a little confused .. I appreciate any help .. thanks a lot :) printf("Enter No of states\n"); Q=5; // scanf("%d",&Q); // READING ZERO MATRIX // reading the matrix from f0.sta { FILE *fp; fp = fopen("c:\\tc\\fuzzy\\f0.sta","r"); for(i=1;i<=Q;i++) for(j=1;j<=Q;j++) fscanf(fp,"%f",&a0[i][j]); fclose(fp); } // READING ONE MATRIX // reading the matrix from f0.sta FILE *fp; fp = fopen("c:\\tc\\fuzzy\\f1.sta","r"); for(i=1;i<=Q;i++) for(j=1;j<=Q;j++) fscanf(fp,"%f",&a1[i][j]); fclose(fp); This is the code bit. c debugging fscanf assertion share|improve this question edited Jan 3 '12 at 18:46 Mysticial 281k35238263 asked Jan 3 '12 at 7:52 abhishek b 3128 Can you put your code here, to let us see how did you try to use the given function? There is no point of describing how you should use fscanf, that's what the documentations are for. You could just read a documentation or you could paste a code example to let us see what you have tried, maybe we can give you a simpl

I have read that it might be caused by a NULL value of a pointer being passed to function. I am reading a file from Visual Studio and I am sure this file exists. How can there be an assertion error? Also, I have found an assert statement in my c program assert(pred_dir<=2); this code was downloaded from assertion error in the internet (the reference software of h.264 video codec) from the internet and I am not quite sure how i would get an error like this. Sorry I could not post the source code because it is too big and consists of four projects. I only modified the code to read a textfile and got this error. Also, what is an unhandled exception, access violation error? c h.264 assertions share|improve this question asked Sep 2 '13 at 17:58 mc8 75215 from the linux man page "assert - abort the program if assertion is false" –sujin Sep 2 '13 at 18:02 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted An assertion is a condition that you, as a programmer, expect to be unequivocally true at a given point in the program. Many programming languages give you a way to assert a condition, and you, as a programmer, can use assertions to find and diagnose many problems before they happen. For example, if at a specific point in your program, you expect a variable called a to be 0, you can write: assert(a == 0); and if during runtime, a is not 0 at that specific part of the p

Program:C:\JM\.\bin\ldecod.exe File: f:\ff\vctools\crt_bld\self_x86\crt\src\fscanf.c Line:52 Expression: (stream!=NULL) For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. (Press Retry to debug the application.) What seems to be the problem here? CODE This is the portion of my code where I used fscanf. When mi=297 it worked perfectly fine. int myframe[29699]; ........ if (CONCEAL==1) { FILE*concealfile; concealfile=fopen("myerrsim%15carphone.txt","r"); for(mi=0; mi<14850; mi++) { fscanf(concealfile,"%d\n", &myframe[mi]); } if (myctr==currMB->mbAddrX+(((currMB)->p_Slice)->p_Img)->number*99 && currMB->mbAddrX+(((currMB)->p_Slice)->p_Img)->number>0) { if (myframe[myctr]==1) { mbmode=0; } myctr++; } } Additional questions! I am encountering several similar errors. The programs breaks at different portions of source codes and some of which are built in functions like "fscanf". I do not know the reason. And sometimes a program on my computer, like "Flash Player" notifies me of some sort of error. Is this because the pointers used in my program are trying to access "Flash Player"? Why is this happening and what is the possible fix? What are assertion errors simply put?
