[ad_1] int ****ptr; ptr = new int***(); *ptr = new int**(); **ptr = new int*(); ***ptr = new int[size_of_arr]; //access (***ptr)[index] delete[] ***ptr; delete **ptr; delete *ptr; delete ptr; 2 [ad_2] solved Allocating array in quadriple pointer [closed]
[ad_1] Problem lies in the order of operations inside while() loop: while (i != 1000) { ++i; num.push_back(i); cout <<num[i]<<“\t”<< sqrt(num[i]) << “\n”; } i starts from 0. In each iteration, you push_back an element and then print it using counter i – after its incrementation. So, num[i] refers to a non-yet-existing element. Change your … Read more
[ad_1] The proposal from comments, in pseudocode (turning into C is homework, so I’m not doing that): make P-A pipe make A-B pipe make B-C pipe if fork() // process A while (read can from P-A pipe) do something to can write can to A-B pipe else if fork() // process B while (read can … Read more
[ad_1] By assuming that you have an array like arr[n]: You can define another array to keep differences like diff[n-1] and then you just need a loop like: for(i=0; i<n-1; i++) { diff[i] = abs(arr[i]-arr[i+1]); } Don’t forget to include <stdio.h> and <stdlib.h>. 0 [ad_2] solved Absolute difference between consecutive array elements
[ad_1] If you are saying that list->at(0) returns NULL Then the pointer pEnd will be NULL. Therefore doing this *pEnd is de-referencing a NULL pointer which will obviously seg fault. If you want to chek for this, you could check the pointer before de-referencing. for eg: if(pEnd == NULL) //Do nothing or throw error or … Read more
[ad_1] You have a question in the format “No A is within a class B”. The algorithm for such problem is bool wrong = false; while ( /* there is another A */ ) { if ( /* check if it is NOT within a class */ ) { wrong=true; break; } } if (wrong) … Read more
[ad_1] 1000 / 500 is an rvalue. Simply put, an rvalue is a temporary value that doesn’t have a name that you can refer to later. paintneeded is an lvalue, and this is what you should be assigning to: paintneeded = 1000 / 500; Although I suspect it would involve the area in the formula … Read more
[ad_1] You code has undefined behavior because you are accessing them beyond the size. In v1 there will be 7 items, while in v2, there will be 3. But you are accessing both upto index 20. So the output can be anything. To avoid this, you can resize your vectors and then assign 1 to … Read more
[ad_1] Because all your data is in the same file, your going to need to take a slightly different approach. Instead of passing in the item to fill out, I would have the function return the list of read questions: public IEnumerable<QuestionUnit> ReadQuestionFile() Then, read in a loop until you reach the end of the … Read more
[ad_1] It looks like you’re asking for interpolation. In which case sure! First you’ll want to construct a map<string, string> of the keys and values, for example: map<string, string> interpolate = { { “F”s, “a && b && c”s }, { “H”s, “p ^ 2 + w”s }, { “K”s, “H > 10 || e … Read more
[ad_1] The honour for the solution goes to @molbdnilo , who noticed a case of undefined behaviour (delete neueTankstelle led to dangling pointer in list). @hyde mentioned the possible case of different file endings. [ad_2] solved Why is my street printed on Linux, but not on Windows?
[ad_1] I think when you write: if (a > b) { max = a; min = b; } else (a < b); { max = b; min = a; } you really want to write: if (a > b) { max = a; min = b; } else { max = b; min = a; … Read more
[ad_1] You cannot create dynamically named variables in C# (and I am with those who are wondering why you want to do that). If you don’t want to use an array, consider a Dictionary — it would perform better than an array in some circumstances. Dictionary<string, int> values = new Dictionary<string, int>(); for (int i … Read more

[ad_1] You must fix your usage of the preprocessor as follows: Include a space between #define and its operand. To implement include guards properly, you need a corresponding #ifndef before the #define. As wildplasser said, you can’t use macro names beginning with underscore(s), so remove them, or replace them with some other prefix of your … Read more
