4.2.3 - Discuss an algorithm to solve a specific problem

Problem

Suppose a programmer wants to develop a program that records temperatures for four cities. The program should ask for each city name, and highest and lowest temperature for a particular year. Three arrays will be used to store the city names, the low temperatures, and the high temperatures. After storing all the data, the program should display a list of cities with high temperatures above the average high, and a list of cities with low temperatures below the average low. The solution to this problem follows.

//p219 Ex24

//A program that outputs the cities with temperatures above the average of high temperatures and cities below the average of low temperatures

TOTALH = 0 //Variable declaration and initialisation (total high)

TOTALL = 0 //Variable declaration and initialisation (total low)

AVGH = 0 //Variable declaration and initialisation (average of high)

AVGL = 0 //Variable declaration and initialisation (average of low)

CITYNAMES = new Array() //Declaration of array that will hold the names

HIGHTEMP = new Array() //Declaration of array for high temperatures

LOWTEMP = new Array() //Declaration of array for low temperatures

output "Hello"

loop I from 0 to 3

CITYNAMES[I] = input("Type the name of the city")

HIGHTEMP[I] = input("Type the Maximum temperature of the city")

LOWTEMP[I] = input("Type the Minimum temperature of the city")

TOTALH = TOTALH + HIGHTEMP[I]

TOTALL = TOTALL + LOWTEMP[I]

end loop

AVGH = TOTALH/4

AVGL = TOTALL/4

output "Cities above Average High:"

loop I from 0 to 3

if HIGHTEMP[I] > AVGH then

output CITYNAMES[I], "+"

end if

end loop

output "Cities below Average Low:"

loop I from 0 to 3

if LOWTEMP[I] < AVGL then

output CITYNAMES[I], "+"

end if

end loop
