System PAUSE and CLS

Question

How can we use system("pause") and system("cls") in here?

Answer 1

Both pause and cls are Windows commands.

OnlineGDB is running on a linux machine, hence the Windows commands do not work there.

"clear" on Linux is the equivalent of "cls" on Windows, however, it does not work in here. It works in your own PC though if you're running Linux.

solution
put it library stdlib.h
and put system ("clear") ;

xxxxxx
check it code

xxxxx

#include <iostream>
#include <stdlib.h>
using namespace std;

int main () {
int n1, n2, res ;
char opc ;

inicio :
system ("clear") ;
cout << " digite nota 1 :  " ;
cin >> n1 ;
cout << " digite nota 2 : " ;
cin >> n2 ;
res = n1+n2 ;

if ( res > 60 )
cout << " aprovado \n" ;

else if ( res > 40 & res < 59 )
cout << " recuperacao \n" ;

else
cout << " reprovado \n" ;

cout << " Digitar outras notas ? [S / N ] " ;
cin >> opc ;

if ( opc == 's' or opc == 'S' )
goto inicio ;

return 0;

}

Answer 2

HI

Not support

They all need to use"#include < Windows.h >"

The GDPOnline IDE does not support it

Function

System (" CLS ") clears the screen
System (" pause ") can display "press any key to continue"
// If you want, download dev-cpp

Answer 3

OnlineGdb work in server host linux , so need library linux to working.

Unique solution is put it library and function sleep.

check code
