[amhiine24]

Hello ! im making my scissor,paper and rock game on c++ program . I need to replace scanf to enter a invisible characters when other user is typing , can you say what
code it is ? thanks
my code:

#include<stdio.h>
#include<conio.h>
main()
{
int a,b;
clrscr();
printf("NOTE:s(scissor),p(paper),r(rock)");
printf("\nPLAYER 1 BEGINS:");
scanf("%s",&a);
printf("\nPLAYER 2 turns:");
scanf("%s",&b);
if (a=='s' && b=='p') printf("P1 WINS!");
else if (a=='p' && b=='r') printf("P1 WINS!");
else if (a=='r' && b=='s') printf("P1 WINS!");
else if (a=='p' && b=='s') printf("P2 WINS!");
else if (a=='s' && b=='r') printf("P2 WINS!");
else if (a=='s' && b=='r') printf("P2 WINS!");
else if (a=='s' && b=='s') printf("DRAW!");

else if (a=='r' && b=='r') printf("DRAW!");
else printf("YOU'RE OUT OF WORLD!");
}
getch();
}

• This is C, you have posted in the C++ forum. You should learn how to read.
• I am willing to bet you are using Turbo C, get a new compiler; one that is standard and still supported
• Look at: How to get input without hitting 'ENTER'-FAQ
• You should also read all the other FAQs as your code is extremely poor.

im sorry i dont know it is a turbo c , because in our class we are using turbo c++

It's amusing how this compiler hangs in there even though it's dinosaur-old . I guess lack of options and brains make your teachers choose it. ( But don't tell them that )
Since you're using TC++ in your class, and assuming that there's no way of making them see the light and dump it, get a new compiler and compile your code in both.
Try to observe the differenses between the two. Remember that Turbo C/C++ outputs 16-bit programs, giving you 1MByte of RAM at most, which will not be supported in future OSs.
