Question

Write a C program that does the following for binary and hexa decimal numbers that performs the same as the output given below.

* Display binary and hexa decimal numbers after conversion from decimal numbers

* Exchange the outer bytes of binary and hexa decimal number

* Exchange the inner bytes of binary and hexa decimal number

* Display number of set bits in each byte

THE C PROGRAM SHOULD GIVE SAME OUTPUT AS THE PICTURE

cc DHEXA DECIMAL o p2x p 2. p2x Input number 287 454 020 Select option. display number in hexadecimal 2 exchange outer bytes 3 exchange inner bytes 4 display number of set bits in each byte exit number 0x11223344 select option. display number in hexadecimal 2 exchange outer bytes 3 exchange inner bytes display number of set bits in each byte exit number before 12233 44 number after 0x 22331 I
