to_string() FunctionSyntaxstring to_string(int/long/long long); Parameternumerical valueReturn valueThe return type of this function is "string".Here is an example with sample input and output:Like we define and declare, int i=5; string s=to_string(i); if(s=="5") cout<<"converted ...
The above output is not correct because usingss.str("")does clear the string, but the issue is that we can’t add new values to the stream. That’s why in the first line, we get the correct output0 0 0, but in the next iteration, both the strings,tempandtemp2, become empty as...
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...

i am gettin a error from string to lpctstr conversion All replies (3) Thursday, March 22, 2012 8:33 AM ✅Answered Ok, you are describing a potential BIG headache for yourself. LPCTSTR is just a typedef that changes to LPCSTR if you don't #define UNICODE, or it could be LPCWSTR if...
To reduce the size you can define a specific entrypoint. To do that, go to your projects properties and under Linker->Advanced first option is EntryPoint, put in the field "_main" (without quotes). Then change your example code to
Compilers can, of course, define the meaning of certain constructs beyond the requirements of the standard, as a compiler extension. Accessing inactive member of a union - especially when all members are PODs - is indeed unlikely to produce surprises, given that most C++ compilers are also...
But once T is deduced to be a std::string, it can’t choose the constructor taking a parameter of type std:string&&. Perhaps surprisingly, the constructor chosen in the second step doesn’t have to be the one used for template parameter deduction.We would then need to construct it like...
