Program Plan Intro

LookupName function using Vector

Program Plan:

• Include the appropriate headers into program.
• Declare the “lookupName()” function.
• Define the function “lookupName()” with three parameters.
  • The first parameter “targetName” is to identify the name in the array.
  • The second parameter “names” is to store names into vector.
  • The third parameter “numbers” is to store numbers into vector.
  • Declare and define the variables with its initialization.
  • Using “for” loop, check the “targetName” is available in array or not.
    • If the condition is true, assign the numbers into variable.
    • Assign the vector values to variable.
  • Return the phone number for the corresponding name.
• Define the “main()” function.
  • Initialize the vectors for names and phone numbers.
  • Add the names and phone numbers to the vector using the function “push_back()”.
  • Using “do-while” loop, prompt the user for name.
    • Call the “lookupName()” function  with appropriate arguments.
    • Using “if-else” condition, check the resultant number is in array or not.
      • If the condition is true, print the result.
      • Otherwise, print “Name not found” statement.
      • Get the sentinel value from user to check in “while” loop.
