This: >>= is the shift right assignment operator which performs the shift right operation on b and reassigns it to b. >>= 1 basically divides b by 2. It shifts all the bits 1 to the right. eg if b in binary is 00000010 (2 in decimal), b >>= 1 would make b = 00000001 … Read more
The issue is that you are mixing an ARC violating construct into ARC’d files through inclusion. You can’t apply -fno-objc-arc to a single header file because that doesn’t make sense. Since it is in a header file, you will either need to use an #if pragma to switch between behaviors depending on whether an ARC … Read more
I want to get a return values 3374747372 as char or string. Casting doesn’t work in this case. You can use text formatting IO to get a hex string representation of the arrays content: unsigned char codeslink[5] ={ 0x33, 0x74, 0x74, 0x73, 0x72}; std::ostringstream oss; oss << std::hex << std::setfill(‘0’); for(size_t i = 0; i … Read more
The text was in some sort of Unicode encoding and why it was acting differently then before with ASCII encoded text. So I did this below before the GetEncoding and it works now. if(!txt.IsNormalized(NormalizationForm.FormKD)) { txt= txt.Normalize(NormalizationForm.FormKD); } solved Encoding.GetEncoding(“Cyrillic”) making all text question marks in .NET

password = str(input(“Enter your password then press enter: “)) while not 6 < len(password) < 12 : password = str(input(“Enter a password that is between 6 and 12 characters: “)) The first line gets the user’s input as a string without a newline character. The second and third lines act as a do-while loop, asking … Read more
First profile. Second, turn up optimizations levels on you compiler. Thirdly, replace your for loop with multiplication / algebra. For example, the linea+=N is the fundamental basis for multiplication (repetitive addition), and the loop can be replaced by:a += j * N; N -= j; Replacing the loop will speed up your program (if your … Read more
You need to anchor your pattern and use lookahead to validate those cases. if(preg_match(‘/^(?=.*[A-Z])(?=.*[a-z])(?=.*[0-9])[a-zA-Z0-9@:.]+$/’, $username)) { … } (?= … ) is a zero-width assertion which does not consume any characters on the string. Therefore, It only matches a position in the string. The point of zero-width is the validation to see if a regular … Read more
The quick and dirty fix is to use something like: level = level.Replace(“‘”,”whatever”); but there are still problems with that. It won’t catch other bad characters and it probably won’t even work for edge cases on the apostrophe. The best solution is to not construct queries that way. Instead, learn how to use parameterised queries … Read more
I think you’re asking how to put that piece of code inside HTML…? If so, it’s easy. Put <script> tags inside your html: <script> function url() { var x = window.location.pathname; if (x==”/index/index.php”) { } } </script> And your JavaScript code will work. If you’re saying you need to write your whole page in JavaScript, … Read more

This should compile, but it will not work as intended. I’m not going to try to fix it because the logic is too broken and handled better by reading up on queues in a text before continuing. I cannot be certain this compiles in Turbo C++. I haven’t used Turbo C++ since the 90’s, and … Read more
