Data and Output requirements for first 211 Program
There are 10 records and the data below is in the order
of the input commands
B M 23 210 3.45 62
W F 27 132 2.90 63
B F 31 122 1.97 58
W M 35 167 1.55 72
W M 33 235 2.89 54
B F 22 124 3.01 60
B M 25 187 3.75 65
W M 41 165 1.93 67
W F 28 145 2.72 72
W F 21 109 2.00 59
oUTPUT IS AS FOLLOWS:
1 AVERAGE WEIGHT OF PEOPLE OVER 160 LBS.
2 NUMBER OF FEMALES WITH GPA UNDER 2.00
3 NUMBER OF MALES GREATER THAN 5 FEET TALL AND UNDER 210 LBS.
4 AVERAGE GPA OF MALES
5 AVERAGE AGE OF FEMALES OVER 5 FEET WITH GPA OVER 2.10
6 TOTAL WEIGHT OF EVERYBODY
7 THE GENDER OF THE TALLEST PERSON
8 THE TOTAL AGE OF PEOPLE UNDER 170 LBS.
9 THE HIGHEST GPA OF WHITE PEOPLE
10 TOTAL BLACK MALES UNDER 30 YRS , OVER 5 FEET AND HAVE GPA > 2.88
aLSO INCLUDE AN ITEMIZED LISTING OF THE DATA (i WILL GIVE YOU
A CLUE ON THIS --- ONLY INVOLVER 3 LINES OF CODE)
RENEMBER THAT ALL AVERAGES INVOLVE 2 TOTALS.....
IMPORTANT TIP..... WHEN DOING AN AVERAGE, IF YOU DIVIDE 2 INTEGERS
YOUR RESULT WILL NOT HAVE ANY DECIMAL ACCURACY. (EVEN IF IT
IS ASSIGNED TO A FLOAT VARIABLE. tO GET AROUND THIS PROBLEM,
USE CASTING.. EXAMPLE Avg_age = (float) totalage / (float) n_people
THERE ARE 2 WAYS TO WRITE THIS PROGRAM.
1 DEAL WITH EACH OUTPUT REQUIREMENT TOTALLY SEPARATELY.
2 TRY TO ELIMINATE REDUNDANT IF STATEMENTS (HARDER)
