How to make a text entry?

Question

Programming

#include
using namespace std;
int main()
{
string s;
cin>>s;
system("PAUSE");
return 0;
}
It is necessary to make it so that with each change in s, the value is written to the textbox, erasing the previous value

Answer 1

it is possible like this:

#include <iostream>
#include <fstream>
#include <string>

using std::cin;
using std::string;


int main(){
  setlocale(LC_ALL,"Russian");
  
  string str;
  while(cin >> str)//While Ctrl-Z (Ctrl-D *nix)
  { 
    std::ofstream exp("text.txt");
    exp << str << std::endl;
  }
}

Answer 2

To do this, you need to "reset" the old value.
Approximately as follows:

#include <stdio.h>
#include <stdlib.h>

int main()
{
int i;
for (i=0;i<3;i++)
    {
    char str[10]="";
    printf("first print %s\n",str);
    scanf("%s",str);
    printf("second print %s\n",str);
    }
return 0;
}

when executed, this will be:
./test
first print
123
second print 123
first print
456
second print 456
first print
789
second print 789
