One button input in C/C++ Console Applications

One button input in C/C++ Console Applications:

Code:

---

#include <iostream>
#include <conio.h>
#include <stdio.h>
#include <windows.h>

/* Some info on include files:

-windows.h is not needed in DevC++
-stdio and conio are C header files, you can use C code in your C++ programs

*/

int main(void)
{
using namespace std;
int input;
// Get input:
input = getch();
putchar (input);
system("cls");
// Check key value
if (input == 49)
{
//49 = value for the "1" key
cout << "You entered " << 1;
}
else if (input == 50)
{
//50 = value for the "2" key
cout << "You entered " << 2;
}
return main();
}

---

Now how do you find the key value of the button you pressed? Run this :)

Code:

---

#include <iostream>
#include <conio.h>
#include <stdio.h>
#include <windows.h>

/* Some info on include files:

-windows.h is not needed in DevC++
-stdio and conio are C header files, you can use C code in your C++ programs

*/

int main(void)
{
using namespace std;
int input;
// Get input:
input = getch();
putchar (input);
system("cls");
// Display value of key
printf("Key Value: %d", input);
return main();
}

Let me know if you have a question on the code, this can be used in place of the "cin" (Console Input) which you will have to input a value and then press Enter. Also with this you can input a letter or a number, but only one, not a string.

Hope this helped some way.
