Linear search in a sorted array

 
#include <stdio.h>
#include <conio.h>

void main( )
{
    int arr[10] = { 1, 2, 3, 9, 11, 13, 17, 25, 57, 90 } ;
    int i, num ;

    clrscr( ) ;

    printf ( \"Enter number to search: \" ) ;
    scanf ( \"%d\", &num ) ;

    for ( i = 0 ; i <= 9 ; i++ )
    {
        if ( arr[9] < num || arr[i] >= num )
        {
            if ( arr[i] == num )
                printf ( \"The number is at position %d in the array.\", i ) ;
            else
                printf ( \"Number is not present in the array.\" ) ;
            break ;
        }
    }

    getch( ) ;
}
