hw07 - Conditional Statements 1

From Linux on the GL machine:

• Write a C program (see below) and save it in a file called dectobin.c in your ./cmsc104/hw07 directory
  
  
• Compile the program:
  gcc -o dectobin dectobin.c
  
  
• Run the program to make sure it works:
  ./dectobin
  
  
• Use the SUBMIT utility turn in the homework.
  submit cs104_grasso hw07 dectobin.c dectobin

Using the dectobin.c code as a template, create a program that does the following:

• Create a function name DecToBin that does the following:
  • Prompt the user to enter a number between 0 and 1024
  • Echo the value back to the user
  • Check to see if the value is in range. If not, print an error message and return -1 from the function to indicate failure
  • Convert that decimal value to it's equivalent in binary
    • Divide the decimal number by 2¹⁰ (1024)
    • If the result is 0
      • print a 0 (leave out the \n newline character)
    • If the result is 1, print a 1 (leave out the \n newline character)
      • print a 0 (leave out the \n newline character)
      • subtract 1024 from the original number
  • Do this for all the other powers of 2, working your way back from 2⁹ (512)
  • print a \n newline character
• Call the function from main()
• For main()'s return statement, return the same value that was returned from the function dec
