It’s pretty simple why it’s crashing when you change that line. In the version that crashes you check whether words[j].find(new_word) is equal to std::string::npos and then call s.erase(s.find(new_word), …). Of course, s.find(new_word) could still be std::string::npos, and string::erase throws an exception when the first argument is out of range. In the version that you say … Read more
Solution was to change datatype of key values from constant character pointer const char * to char array. char fruit[sizeof(“fruit”)] = “fruit”; char apple[sizeof(“apple”)] = “apple”; Additionally , even using string instead of const char * for key-values gives similar issue as mentioned in the question, somehow I could make it work only with char … Read more
The *fp is a global variable, so each therad will initialize it with fopen and after finished working try to close it. the *fp is shared between threads (which should not be) so each thread before exiting tries to close the file handle stored in *fp and the double free occurs when multiple threads tries … Read more
Get extension is a function and you have < between it and its () Replace this: string sFileExt1 = Path.GetExtension < (objFI[0].Name); With: string sFileExt1 = Path.GetExtension(objFI[0].Name); 3 solved Operator ‘
You are probably passing a value that can’t be parsed into an int for this parameter: pram[5] = new SqlParameter(“@contact”, SqlDbType.Int, 100); Check what you are passing here: pram[5].Value = contact; If contact is a string then do something like: int contactNumber; pram[5].Value = int.TryParse(contact, out contactNumber) ? contactNumber : 0; 4 solved SQL – … Read more
I believe this is what you’re looking for. The jist is, the compiler needs to verify statically that you’re returning something from every code path. Because you’re using this extension method, it’s not able to deduce the fact, and you’re getting the error: CS0161 ‘Foo()’: not all code paths return a value solved Extension method … Read more
Your function is declared to return char and you are returning an array of char. But even if you fix the return value which should be char * it’s still wrong because you should not return a local variable, instead pass the array as an argument to the function like this void n_zeroes(int n, char … Read more
Rather than storing data in an asp:TextBox, you should consider some other methods of storing values. For example, you can use the HttpApplicationState class in System.Web to store a variety of different data types. If you wanted to store a DataTable using this method, you could do so by doing something like this in C#: … Read more
Return some value via return statement regardress of value of lookup[i][j]. For example, return 0 because I don’t know the correct value to return. int f(long long int arr[], long long int x, long long int y) { long long int i = x, j = y; if(lookup[i][j] == 0) { if(i == j) lookup[i][j] … Read more
c#.net compiles to MSIL. In MSIL both examples are represented exactly the same. Something along the lines of load variable blahblah load constant 123 compare for equality MSIL doesn’t care about whitespace. Decompilers simply translate MSIL back to C#. Both examples would decompile the same, since they both generate the same MSIL 1 solved If … Read more
In your Insert function, you never allocate newNode. Node* newNode; You need to allocate it like so: Node* newNode = new Node(); The program runs correctly after fixing this, and the output is: 24 http://ideone.com/16XL5W EDIT: Regarding your comment below, the following lines do not allocate anything: Node* newNode; struct Node* newNode; They are simply … Read more

I had: for (int i=0; i<6;i++) { S[i].resize(n); } where S is a std::vector. I replaced 6 (the loop extent) with m (even though m = 6). This seems to have solved the issue. Undefined behaviour at its best. 2 solved How can a function finish it’s objective, only to break down after returning to … Read more
There will be exactly n iterations of the first loop. There will be exactly n(n+1)/2 iterations of the second loop. Inside of the second loop there is roughly 1/3 of n/2 long loops, 1/3 of j long loops and 1/3 of 2 long loops. If we look only at the first of the three possible … Read more
