getting rid of previous text

[skorm909]

ok so if i have somthing like

#include <iostream>

using namespace std;

int main(){
    int action;
    cout << "have this show up first" << endl;
    cout << "then have an if statement here" << endl;
    cin >> action;
    if (action == 1){
               cout << "then have this show up but none of the above text ^^." << endl;
               }
    system("pause");
    return 0;
    
    }

how would i do that so it does what it says in the "cout"?

[MyrtleTurtle]

some people use

system("cls");

Here's one example.

i tried that it didnt work it when i put in the IF statement it got rid of all the stuff...

[MyrtleTurtle]

It worked when I did it just now:

if (action == 1){
               system("cls");
               cout << "then have this show up but none of the above text ^^." << endl;
               }

According to this site you can also use clrscr(); if you have Borland C++ Builder.

Could you please give us an example of what you want rather than half an explanation using strange code?

ok so what i want is for me to be able to go through my script and as i go to another item it gets rid of the previous text...
heres an example...

#include <iostream>
using namespace std;

}

thats my script and i want it to be able to like as i go from "mainmenu" to say Europe, the main menu dosnt show up anymore and then if i pick something in Europe it makes the previous text disappear and only show whats next

Then just put the system("cls"); command immediately before the new menu is displayed.

We usually don't recommend doing things like this though because there is no standard way to clear the screen. It's different for each O/S.
