Write a C program called "convert" that reads a signed decimal integer from the user and prints the number in 4 different ways: signed decimal, unsigned decimal, hexadecimal, and binary. 

Here are a few example runs of the program: 

 $ ./convert -1 signed dec: -1 unsigned dec: 4294967295 

hex: binary:

ffffffff 1111 1111 1111 1111 1111 1111 1111 1111 

$ ./convert 256 signed dec: unsigned dec: 256 hex: 100 binary: 0000 0000 0000 0000 0000 0001 0000 0000 

256

There is a bash shell trick that you might find useful for testing your program. You can evaluate an arithmetic expression like this: 

 $ echo $(( 1 + 2 + 3 )) 6 

In addition, you can take the output of one program, and feed it as a user input to another program by chaining the two programs with | character. So, you can input the minimum 32-bit integer like this: 

 $ echo $(( -2 * 1024 * 1024 * 1024 )) | ./convert signed dec: -2147483648 unsigned dec: 2147483648 hex: 80000000 

 binary: 1000 0000 0000 0000 0000 0000 0000 0000 

Note that your program must behave EXACTLY the same as the sample runs shown above. Given the same number, your program must generate the EXACT same output--same order, same strings, same spacing.
