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
