Problem Statement -
Design a program that will allow a user to Input a list of your family members along with their age and state where they reside. Determine and print the average age of your family and print the names of anyone who live in Texas. Family contains a maximum of ten members.

Pseudocode:

//Main Method
MAIN

//variable declarations
//create parallel array to store family members information

//array of Strings for family names
DECLARE names[10] of STRING
//array of ages for family members
DECLARE ages[10] of INTEGER
//array of states where they reside
DECLARE states[10] of STRING

//stores the total number of family members
//as entered by user
DECLARE count as INTEGER

//age average
DECLARE average as FLOAT

DECLARE count as INTEGER
SET count = 10

//declare variables to store current user input
DECLARE name as STRING
DECLARE age as INTEGER
DECLARE state as STRING

//prompt for family member count
WRITE "How many family members do you have? "
//read the value from user
INPUT count

//use for loop to prompt user to enter information
//for all family members
//repeat the loop "count" times
FOR (COUNTER=1; counter <= count; COUNTER++) //prompt for name WRITE "Enter family member name: " INPUT name //prompt for age WRITE "Enter family member age: " INPUT age //prompt for state WRITE "Enter family member state: " INPUT state //store input values in the array SET names[COUNTER] = name SET ages[COUNTER] = age SET states[COUNTER] = state
END FOR //continue with next iteration

//at this point all values are in the array
//call calculate average submodule and store result to variable

CalculateAverageAge(ages,count, averag)

//print average
WRITE "The average age of all family members is ", average

// call method to print whose who live in texas
CALL DisplayMembersInTexas(names, states, count);

END main

//
// Subprogram to calculate average of array values
// returns average as float
//
SUBPROGRAM FLOAT CalculateAverageAge (ages[] of INTEGER, size as INTEGER, average as REF)
DECLARE sumOfAges as FLOAT
DECLARE averageOfAges as FLOAT

//start with total sum zero
SET sumOfAges = 0

//use for loop to calculate the sum of all values
FOR (COUNTER=1; counter <= count; COUNTER++) //update the sum, increase by current array value SET sumOfAges = sumOfAges + ages [COUNTER]
END FOR

//we have the sum of all values
//divide by size to get average

SET averageOfAges = sumOfAges / size

END SUBPROGRAM

//
// Subprogram to print family members who live in texas
//
SUBPROGRAM DisplayMembersInTexas (names[] of STRING, states [] of STRING, size as INTEGER)

//use for-loop to process each value in states array and print the ones which match Texas
FOR (COUNTER=1; counter <= count; COUNTER++) //check the state //if it matches Texas print the name IF states [COUNTER] == "Texas" THEN WRITE names [COUNTER], " lives in Texas" ENDIF
END FOR

END SUBPROGRAM
