I think your problem is that these lines: if (que1.empty()){ for (int m = j; m < counterq2; m++){ que_merge.push_back(que2.at(m)); } } else { for (int l = i; l < counterq1; ++l) { que_merge.push_back(que1.at(l)); } } doesn’t do what you expect. As far as I can see, your idea is to merge the remaining … Read more
You are going to be able to call the element with xpath: //Span[contains(text(), ‘new’)] (assuming Span is with capital letter which is unlikely) or //span[contains(text(), ‘new’)] If there are multiple span elements with text ‘new’ in it, you can try: //td[@class=”status”]/span[contains(text(), ‘new’)] 0 solved How to locate a webtable cell with specific text in selenium … Read more
Your error says everything you need to know here. There’s no default cast for string to your Models.Emails type. Emails is essentially an ID with a collection of e-mail addresses, it appears. I would recommend using the .Net System.Net.Mail namespace instead of what you’re doing here with strings, but in a lightweight application, strings are … Read more
In C++ you can cast a pointer to a base type into a pointer to a derived type using dynamic_cast, assuming it pointed to the derived type in the first place. class A { }; class B : public A { }; int main() { A * a = new B(); B * b = … Read more
This is expected. In the standard there’re no guarantees regarding the order of elements in std::unordered_map. solved Doesn’t std::unordred_map preserve insertion order? [duplicate]
for each value sum has to be zero that is first correction.and i has to be assigned to variable temp because i value has to be checked if it is armstrong number or not.do the changes it will work. #include<stdio.h> int main() { int i, rem, sum=0, temp; for(i=0; i<1000; i++) { temp = i; … Read more
Not the most elegant solution but this should work #include <iostream> #include <vector> #include <string> #include <sstream> using namespace std; vector<string> split(string str, char delimiter) { vector<string> internal; stringstream ss(str); string tok; while(getline(ss, tok, delimiter)) { internal.push_back(tok); } return internal; } int main(int argc, char **argv) { string str = “My name is bob.I am … Read more
Do not mix declaration with definition/instantiation in a .h file. Your are instantiating g_font, g_window and g_renderer in isolation.h file. The correct is instantiating only once, usually, in a .cpp To solve your problem, change isolation.h to declare those variables as external linkage: //load global front extern TTF_Font* g_font; //window extern SDL_Window* g_window; //renderer extern … Read more
Calling fflush(stdin); invokes undefined behavior. You should not use this to flush characters from the standard input buffer. Instead, you can read the characters upto the next linefeed and ignore them: int c; while ((c = getchar()) != EOF && c != ‘\n’) continue; You can also use scanf() for this, but it is tricky: … Read more
I think you can do it using a positive lookahead until you encounter INFO or DEBUG or WARN. ERROR[\S\s]*?(?=\s+INFO|DEBUG|WARN) Match ERROR Match any whitespace character or any non-whitespace character zero or more times non greedy [\S\s]* A positive lookahead (?= Assert that what follows is one or more whitespaces \s+ Followed by either INFO or … Read more
Here are some issues I found. 1. Don’t use struct when referring to variable types. Incorrect: void getTime(struct Time *time) Correct: void getTime(Time * time) Pass by reference, not pointer:void getTime(Time& time) You need to use either . syntax to refer to members or ->:cin >> time->hours; // if passed by pointer.cin >> time.hours; // … Read more
First, fgets will get a string with charactor ‘\n’ when size of inserted string <(255-1). So, let’s set the \n to \0: fgets(cmd, 255, stdin); cmd[strlen(cmd) – 1] = ‘\0’; CreateProcess(cmd, NULL, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi); Second, more instances of cmd to popup in the command line. If what you mean … Read more
This is your program with minimal changes: #include <stdio.h> #include <stdlib.h> void main(void) { int n = 1, i = 0; char a = 0; char *str = NULL; str = malloc(sizeof(char) * (n+1)); // reserve space for a zero byte printf(“Enter string : “); while (a != ‘\n’) { a = getchar(); str = … Read more
Thank you all very much for your input. Actually the first thing i should have checked was at fault, being the HDD, which wasn’t able to provide the needed datarate. I’m now thinking about switching to a SSD – Device. solved Slowdown when reading big file randomly with C++
Vectors in c++ are dynamically sized. You can create a vector without a size argument in the constructor then push size number of elements like so: vector<int> makeGaps (int size){ vector<int> vectorOfGaps; for(int i = 0; i < size;i++){ vectorOfGaps.push_back(i); } return vectorOfGaps; } Edit: Also, as someone already pointed out in your comments, it … Read more
