interactive shell and C compilation inside emacs

Question

I compiled a simple program in C (it does the sum of 2 numbers), by doing :

M-x compile RET
gcc -dummy.c -o dummy
M-x shell RET
./dummy

I get a prompt for the first number I can enter, then nothing is happening. I mean I can enter the first number, do RET, enter the second number (even though I don't have the prompt for this one) and I can get the result with Ctrl-D. So, very ugly. Any idea what is happening under the hood and what I should do to improve that? Thanks

here is the code :

int main()
{
    int nb1,nb2;
    printf("please enter nb1");
    scanf("%d \n", &nb1);
    printf("please enter nb2");
    scanf("%d \n", &nb2);
    printf("the sum:");
    printf("%d + %d = %d", nb1, nb2, nb1 + nb2);
    return 0;
}

One solution is to use M-x term or M-x ansi-term. This will give you a real terminal emulator instead of shell-mode.
