Someone please explain me the following statement for bubble sort 👉 for ( d = 0 ; d < n - c - 1; d++ )

Question

/* Bubble sort code */
#include <stdio.h>
int main ()
{
int array [ 100 ] , n , c , d , swap ;
printf ( "Enter number of elements \n " ) ;
scanf ( "%d" , & n ) ;
printf ( "Enter %d integers \n " , n ) ;
for ( c = 0; c < n ; c ++ )
scanf ( "%d" , &array [ c ]) ;
for ( c = 0 ; c < n - 1 ; c ++ )
{
for ( d = 0 ; d < n - c - 1; d++ )
{
if ( array [ d] > array [ d+ 1]) /* For decreasing order use < */
{
swap = array [ d ] ;
array [ d] = array [ d +1 ] ;
array [ d+ 1] = swap ;
}
}
}
printf ( "Sorted list in ascending order: \n " ) ;
for ( c = 0; c < n ; c ++ )
printf ( "%d \n " , array [ c ]) ;
return 0 ;
}

Answer 1

THIS FOR LOOP IS USE TO MOVE HIGHEST NUMBER TOWARD RIGHT SIDE.

TRY TO SOLVE IT THROUGH EXAMPLE.

TAKE AN ARRAY OF SUPPOSE 5 ELEMENT.

FOR EG [6,7,3,4,9].
