Chapter 17, Problem 3PC

Program Plan Intro

Capital Quiz

Program plan:

• Include the required header files in the program.
• In main() function,
  • Include the required function prototypes.
  • Declare the constant variable “TOT_QUES”
  • Declare the map to store state capitals.
  • Build the map with state capitals.
  • Call the quiz function.
• In function “separate()”,
  • Variable to hold the starting position of the next token.
  • Finding first occurrence of the delimiter.
  • While to check whether it runs out of delimiter.
    • Extracting the token.
    • Pushing the token into vector.
    • Moving delimiter to pint the next position.
    • Move “tok_start” to “delPos”.
    • Search next occurrences of the delimiter.
    • Extracting the last token using the “if” statement.
      • Extracting the token.
      • Pushing the token into the vector.
• In function “get_Map()”,
  • Variable to hold the line of input.
  • Create an input file.
  • Create a vector to hold the state capital.
  • Open the file “Capital.txt”.
  • Read the first line using “getLine()”.
  • Process the file using “while()” loop.
    • Tokenize the line using the “separate()”.
    • Adding the tokens to the map using emplace function.
    • Clear the token using “clear()”.
    • Read the next line using “getline()”.
  • Close the file using “close()”.
• In function “questions()”,
  • Declare the counter for correct and incorrect options.
  • Declare the variable to hold the user’s response.
  • Create iterator for the map.
  • Seed the random number generator.
  • Display the number of questions.
  • Iterate till the total number of question using the “for()” loop.
    • Get a random number in the range of 1-50.
    • Initialize the iterator from the first element.
    • Using the iterator to move nth element in the map.
      • Increment the iterator.
    • Check if the entered response is correct or in correct.
      • Increment the correct response counter.
    • Otherwise increment the incorrect response counter.
  • Display the results.
