How can I use setw() with input stream [closed]

I know some people will say this question is repeated but I really couldn't find a useful answer.

Let's say I have the following program:

#include <iostream> #include <string> using std::cout; int main(){ std::string something; cout<<"Type something"; std::cin>>something; } 

How can I use setw() so the output will look like this?

Type something "then after some whitespaces for example 10 the user will start typing" 

I tried to use setw() in output:

 #include <iostream> #include <string> #include <iomanip> using std::cout; int main(){ std::string something; cout<<std::left<<std::setw(24)<<"Type something"; std::cin>>something; } 

The expected output was supposed to be:

The actual output is:

I can't reproduce what you say, the code you have showed works fine for me.

#include <iostream> #include <string> #include <iomanip> int main(){ std::string something; std::cout << std::left << std::setw(24) << "Type something"; // prints "Type something " std::cin >> something; return 0; } 

That said, you could simply output a string with the desired number of spaces:

#include <iostream> #include <string> int main(){ std::string something; std::cout << "Type something "; // alternatively: // std::cout << "Type something" << std::string(10, ' '); std::cin >> something; } 

One possible solution might be using any special character after setw

Sample Code:

int main() { std::string something; cout<< "Type something" << setw(24) << ":"; std::cin>>something; } 

Output:

Type something :inputString
