Answer
# 1
#include <stdio.h>

void reverse ( int* ip_array, int st_pos, int ed_pos )
{
if ( ( ip_array ) && ( st_pos < ed_pos ) ) {
* ( ip_array + st_pos ) ^= * ( ip_array +
ed_pos ) ^= * ( ip_array + st_pos ) ^= * ( ip_array +
ed_pos );
reverse ( ip_array, ++st_pos, --ed_pos );
}
}

int main ( int argc, char* argv [] )
{
int int_array [20];
int number = 789876;
int counter = 0;
int nloop = 0;
int start_pos = 2;
int end_pos = 5;

/* split the number into an array */
while ( number ) {
int_array [ counter++ ] = number % 10;
number = number / 10;
}

/* reverse the splited array */
reverse ( int_array, 0, counter - 1 );

/* reverse for the particular position */
if ( ( start_pos < end_pos ) && ( end_pos <=
counter ) ) {
reverse ( int_array, ( start_pos - 1 ), (
end_pos - 1 ) );

number = 0;
for ( nloop = 0; nloop < counter; nloop++ )
{
number *= 10;
number += int_array [ nloop ];
}

printf ( "\n %d", number );
}

return ( 0 );
}
