In this example, we define the parseString function, which uses std::string::find to locate the delimiter in the string. We then use std::string::substr to extract the tokens between the delimiters. This method is particularly useful when you need to handle strings that may contain multiple...
All sorts of operations are done with arrays with different complexities, and comparison operations are no different. When we compare two values, we intend to understand how similar or dissimilar they are. With numbers (integers and float), characters, and strings, it can be straightforward. Howe...
to compare them, you can say if (character == '\"') or if(string1 == string2) where the strings have " in them possibly but I am not sure if this helps you. maybe what you want is: if (string[index] == '\"' && string[index+1] == '\"') or string quotes = "\"\...

Still better, I would read the strings from a string table, making a better internationalization-aware code.And I would also use a member variable to represent the control in MFC, e.g. an instance of CStatic for your static control. In this way, you don't need casts (which IMHO should...
When passing its value to a function from cstdlib, which is waiting for a C string, you can get undefined behavior. You can easily miss it, if in most cases that you are testing, there is std::string or null-terminated strings used. ...
byte variable, then Read is able to write to 4 bytes, the lack of a const in the prototype means that writing is possible even if the code itself doesn't write. This is two bytes of a, and two bytes in memory next to a that could belong to another variable, this is stack ...
The extra bit of data seems to have shifted things 28 bytes. So, there's the name of the two functions, "a_constructor" (14 bytes with null terminator), and "main" (5 bytes with null terminator) and the two format strings, "%s\n" (2*4 bytes with the newline as 1 character ...
As you see for short strings passing by value might be “slower” when you pass some existing string - because you have two copies rather than one. On the other hand, the compiler might optimise the code better when it sees a value. What’s more, short strings are cheap to copy so ...
