There are lots of bugs. The corrected version...

/* Pad.c */

#include <stdio.h>
#include <string.h>

main()
{
 char Text[20][81], CharTemp;
 int Count,Counter,Temp, i;

 for( i = 0; i < 20; i++)//bug 1
  strcpy(Text[i], "");

 puts("This will \"pad\" your lines");
 puts("Type quit on a newline to exit");

 Count = -1; // Bug 2.

 do
 {
  Count++;
  printf(">");
  gets(Text[Count]);
 } while(( strcmp("quit",Text[Count]) != 0 ) && (Count < 20)); // Bug 3.

 for( Counter = 0; Counter < Count; Counter++ ) // Bug 4
  if( strlen(Text[Counter]) < 70)
    for( Temp = strlen( Text[Counter] ); Temp <= 70; Temp++ )
     strcat(Text[Counter],".");

 for( Counter = 0; Counter < 20; Counter++ ) // Bug 5.
  printf("\n%s",Text[Counter]);
}

Hope this does it.
