Is there a way to restart a program from the biggining.

What I want is something like:

printf ("data is wrong do you want to re-enter it or do onther student.\n");

I like to give the person a chose to reenter it or just start over the program.

I know there a way to end just wander if they have one for this. If not I have to do some breack loop back in the int main() and I do not really want to do that.

Thanks

I'm tempted to say use a goto statement. But thats not very popular or favored amongst programmers. It would be nice to see your code.

Rather then goto i would use some loop statement with continue & break, ie:

	for ( ;; )

	{

		int result;


		result = 0;

		result = getInput();

		if ( 0 == result )

		{

			// fail;

			continue;

		} // if


		break;

	} // for

Ok I not going to put the real program in here because its too long. So I just wroght this one that should have the idea. There maybe mitakes I have not run in though compiler or debuged it.

#include <stdio.h>

#include <ctype.h>


void getClass (int class);

void getHours (int hours);


int main ()

{

     int class[1]; int hours[1]; int x=1; char option;


     do{

          getClass (class);

          getHours (hours);

          

          printf ("Do you want to do anther student? Y for yes and N for No n");

          scanf ("%c",option); toupper(option)

     

          if (option == 'N')  

               x=0;

     

     }while (x==1);


     return 0;

}


void getClass (int class)

{

     printf ("Enter in the class number");

     scanf ("%d",class[0]);

     printf ("\n");

}


getHours (int hours)

{

     case 1234 : hours[0] = 3;

     case 2134 : hours[0] = 1;

     case 1243 : hours[0] = 3;

     case 1324 : hours[0] = 4;

     default : // This is were I like it to start the program over.

}

Ya this is much more simple code but the idea is there. Hope you guys understand it better now.
