Supposing that both are pointers (of compatible types), if(!http_piconpath) http_piconpath = http_tpl; Or http_piconpath = http_piconpath ? http_piconpath : http_tpl; If picon is null, it gets the value of tpl; if both are null, nothing changes. solved C++ get variable from variable [closed]
Issues that I see: Issue 1: struct theFile{ FILE *fPointer; char *fileItems[]; int count; }myFile; is not valid. The flexible array member has to be the last member of the struct. Use struct theFile{ FILE *fPointer; int count; char fileItems[]; // This is an array of char not an array of char*. }myFile; instead. Issue … Read more

I teste with this code, it works fine for me #include <stdio.h> #include <string.h> int main() { char string[] = {“0001-01-01T17:45:33\0”}; char *temp; temp = strchr(string, ‘T’) ; *temp= ‘ ‘; printf(“%s\n”, temp); printf(“%s\n”, string); } 2 solved convert an ISO8601 timestamp with C code [duplicate]
The problem is because you call that function in a while, and because of for(counter = 1; counter < 51; counter++) the counter will become again 51 (everytime the function is called) and then will enter again in that if (counter == 51). To resolve that you could declare a global variable int ok = … Read more
Assuming you have other threads running apart from main, you can use use a sem_wait (semaphore initialized to 0) in main() and then from your thread you can call sem_post whenever you want main() to run.

A quick primer on OpenFileDialog: You almost never assign a value to FileName, as this value is the path to the file the user selected. You can use it to pre-populate the file name, but if the file doesn’t exist in the start folder, it may well revert to String.Empty (the behavior you described). The … Read more
You just: std::sort(v.begin(), v.end()); std::pair is lexicographically compared. On the other hand if you want to sort them with respect the second element of the std::pair then you would have to defind a custom comparator in the following manner: std::sort(v.begin(), v.end(), [](std::pair<int, std::string> const &p1, std::pair<int, std::string> const &p2) { return (p1.second == p2.second)? p1.first … Read more
The answer goes like this. In C, the natural way to deal with an array of [0,1] is by treating them as bits. The 2^24 permutations of 24 bits are precisely the values of unsigned int from 0 to 2^24-1. So the question essentially is how to write the code based on that data structure. … Read more
The keyword new lets you create a new object. C++ is a little different than a language like .Net or Java, if you are familiar with those languages. The C++ languages uses the keyword new, but new return a “pointer” to the new object. If your class is named “Bet”, then the statement: Bet *betPointer … Read more

On the coding side, since this is C++, don’t store lists of strings in a two-dimensional array of char. Try std::vector<std::string> instead. And don’t read your file one character at a time; read larger blocks of characters. If you can guarantee that there are never spaces embedded within first names, you can write something like … Read more
