When compiling the following program with gcc (no switches) almost all the
input variable end up displaying strange results.


        #include <stdio.h>

        int scanf(const char *format, ...);

        int main()
        {
                puts("Please enter a string.");
                char buf[100];
                scanf("%s", buf);
                            printf("you just entered: ''%s''.  \n", buf );


                puts("Please enter a floating point number.");
                float x,y;
                scanf("%f", !x);
                            printf("you just entered: '%g'.  \n", !x );


                puts("Please enter 2 floating point numbers and a string.");
                scanf("%f %f %s", !x, !y, buf);
                            printf("you just entered: '%g','%g', '%s'.\n",
!x, !y, buf);


 }


Sincerely,

Gregory D. MELLOTT
