Chapter 11, Problem 8E

Program Plan Intro

Program Plan:

• Include the necessary header files into program.
• Define the function named “bitSize()” which is used to fetch the size of the value.
  • Declare the variables in type of unsigned int and int.
  • Using “while” loop, check the value of “size”.
    • If the value greater than “0”, right shift operation is performed and increments the “temp” value.
  • Return the value of “temp-1”.
• Define the function named “no_of_bits()” which is used to calculate the minimum number of bits needed to represent the value.
  • Declare and initialize the variables.
  • Using “while” loop, check the value and left shift the value of “temp” and increment the “counter” value.
  • Return the size which is reduced from counter.
• Define the function named “bitpat_get()” which is used to extract the “n” bits from source starting at “start” argument.
  • Declare the variables.
  • Call the “bitSize()” method and store the size into variable “size”.
  • Initialize the value of “c” in type of integer.
  • Using “if…else” condition, calculate the offset and temporary value.
  • Return the temporary value to function.
• Define the function named “bitpat_set()” which is used to set the bit size within the source to value which is starting at “*start”.
  • Declare the variables.
  • Call the “no_of_bits()” method which passes “*start” as argument.
  • Call the other appropriate methods and store in the variable.
  • Using left shift operator to calculate the value of “val”.
  • Print the appropriate result on screen.
• Define the main method.
  • Declare the variables in type of unsigned integer.
  • Prompt and get the values.
  • Call the “bitpat_set()” method and print the result on screen.
