[ad_1] Excellent idea! Here’s a program that prints “hellohello” five times: int i; void print_twice(const std::string& s) { for (i = 0; i < 2; i++) { std::cout << s; } std::cout << std::endl; } int main() { for (i = 0; i < 5; i++) { print_twice(“hello”); } } Or… does it? (Ominous organ … Read more
[ad_1] There is no instance or extension method in .NET for a sequence of strings that will join them together as String.Join does. If you want such an extension method you’ll have to write it yourself (which should be trivially easy, given that internally all it needs to do is call string.Join). Enumerable.Join, which is … Read more
[ad_1] As mentioned std::vector::push_back() may invalidate your iterator. Possible, but pretty ugly solution could be: for (auto beg = v.begin(); beg != v.end();++beg) { if (beg == v.begin()) { v.push_back(50); beg = v.begin(); } } but your logic seems convoluted, why not push back just before the loop? 4 [ad_2] solved C++ why this code … Read more
[ad_1] Adding strings concatenates the strings. Use TryParse to parse the strings into integers or doubles. Remember to check the return value! You must handle the case where the user fails to type in a valid number. The reason I use the var keyword is because I want the person who is playing be able … Read more
[ad_1] All three options to check for empty container are more or less equivalent. Using empty() shows (as denoted in the comments already) most obviously your intention and as a little bonus, it is even the shortest one to write (that’s for the lazy ones like me…). How it is implemented? Vendor specific, probably inlined. … Read more
[ad_1] The book you are reading is crap. Avoid the book and tell others to do the same. <conio.h> is a system-specific header and not guaranteed to be available on many platforms. The result of fgetc must never be stored in a char variable. The function feof must never be used in a loop condition. … Read more
[ad_1] Answering the literal question as stated… The reason for the warning is simply because the left side of the comma in the for loop, third section, will have no effect. i+8 does not change anything, but rather returns a value. Instead, you are wanting the compound assignment addition operator, += i+=8, which will add … Read more
[ad_1] What’s unity? float results = OriginalValue – (OriginalValue * Percent / 100); 6 [ad_2] solved How to decrease a number with a percentage C# [closed]
[ad_1] I don’t know where you got data from, but you need to change it to array<int, 3> or make compareByValue a template: bool compareByValue(const array<int, 3> &a, const array<int, 3>&b) { return a[0] < b[0]; } 2 [ad_2] solved Sorting vector of arrays by array’s element
[ad_1] I won’t go into too much detail, but “client.dll”+0065F38 won’t help you too much. Luckily for you, I wrote a tutorial of how to write a trainer in C#. 2 [ad_2] solved Find address using pointer and offset C# [closed]
[ad_1] The compiler assigns offsets to all members, and includes these in all load/store operations on members: struct foo { uint32_t bar; uint32_t baz; uint32_t get_baz() { return baz; } }; uint32_t get_baz_from_foo(foo *f) { return f->baz; } becomes (ARM assembler code used for simplicity): foo__get_baz: ; calling convention: this pointer in r3 ; load … Read more
[ad_1] Here’s how to do it using the Javascript API v3: https://developers.google.com/maps/documentation/javascript/overlays#Polylines But it sounds like you may be using some sort of control that does it for you in C#. I’m going to guess because you haven’t provided more information about what you are using to create the map, but let’s assume you’re using: … Read more
[ad_1] It’s easy enough if you are using std::string to hold your value. #include <string> #include <algorithm> std::string input = …; input.erase(std::remove(input.begin(), input.end(), ‘Ì’), input.end()); It’s more complex if you insist on using C strings or arrays. I see from the comments above that you are using C strings. I suggest you switch to using … Read more
[ad_1] You can make them instance variables of the class containing the two methods. This way, they are accessible to all the methods of the class, and it’s value is preserved between the calls to those methods. class ContainingClass { int randomNumber; int randomNumber2; public void generateNumbers() { Random rand = new Random(); randomNumber = … Read more
[ad_1] Your messagereturn() and greet() functions are declared as returning bool values, but neither one of them actually returns anything, so the values are random. Since you are sending the return values to std::cout, but the functions send their own messages to std::cout directly, they should not be returning any bool values at all. Also, … Read more
