C/C++ code

[SirGuga]

I´m making a C/c++ program and need two commands.
1- I need a command to make a cs (Clear Screen) and on what library is it.
2- Need to make an input from the keyboard of a single character. I can´t remember the command to reed this character without having to press enter after the character


Thanks......

To clear the screen include stdlib.h and use system("cls") for DOS and system("clear") for UNIX. To read a single character from the keyboard, use getchar(); Here's a sample:

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

main() {
char inputchar;
printf("Clear screen? ");
inputchar = getchar();
if(inputchar == 'y') {
system("cls"); // system("clear") for UNIX
printf("You cleared the screen\n");
} else
printf("You didn't clear the screen\n");

return 0;
}

1. i use clrscr() in conio.h (i think)
2. i use :
#include<iostream.h>
Char varname; // declare it as a character
cout << "Please input something: ";
cin >> varname; //prompt to user to input something

Help!!! I'm swimming with the sharks...!!

both correct!

FYI: Some conio functions aren't supported by some compilers.

A universal way to clear the screen is to write a whole bunch (50 at most) of '\n' characters to the screen.
