Use of the goto statement

Program 19) This program illustrates the use of the goto statement. The program evaluates the square root for five numbers. The variable count keeps the count of numbers read. When count is less than or equal to 5, go to read; directs the control to the label read; otherwise, the program prints a message and stops.

                                         PROGRAM

#include <math.h>
main ( )
 {
         double x, y ;
         int count ;

        count = 1 ;
        printf ("Enter FIVE real values in a LINE \N") ;
read:
        scanf ("%if",&x) ;
        printf("\n") ;
       if (x<0)
          printf ("Value - %d is negative\n" ,count) ;
          else
            {
                y = sqrt(x) ;
                printf ("%1f\t %1f\n", x, y) ;
            }
            count = count +1 ;
            if (count <= 5)
  go to read ;
            printf ("\nEnd of computation") ;
         getch( ) ;
 }

Output:     Enter FIVE real values in a LINE
                 50.70  40  -36  75  11.25
                 50.750000         7.123903
                 40.000000         6.324555
                 Value -3 is negative
                 75.000000         8.660254
                 11.250000         3.354102
