Write a program to set bits within a range of bits to $1$s for an int variable num. Read in num, start bit, and end bit using "scanf". Display num in binary form before and after setting the bits.

Output example:

Enter a number: $478$

$00000000000000000000000111011110$

Enter the start bit $(0-31)$: $20$

Enter the end bit $(0-31)$: $18$

The new number: $1835486$

$00000000000111000000000111011110$
