1.1 - Display linked data

Write a program that asks the user to enter the name and grade for three pupils. Store the names in one array and the grades in another (parallel arrays). After all details have been entered, display each pupil’s name followed by the grade they achieved as shown.

Enter pupil 1 name: Jane
Enter pupil 1 grade: A

Enter pupil 2 name: John
Enter pupil 2 grade: B

Enter pupil 3 name: Jess
Enter pupil 3 grade: C

Test Results
Jane achieved grade A
John achieved grade B
Jess achieved grade C
DECLARE names[3] AS STRING
DECLARE grades[3] AS STRING

FOR i FROM 0 TO 2 DO
    RECEIVE names[i] FROM KEYBOARD WITH PROMPT "Enter pupil " & (i+1) & " name: "
    RECEIVE grades[i] FROM KEYBOARD WITH PROMPT "Enter pupil " & (i+1) & " grade: "
    OUTPUT BLANK LINE
END FOR

OUTPUT "Test Results"
FOR i FROM 0 TO 2 DO
    OUTPUT names[i] & " achieved grade " & grades[i]
END FOR

 

names = [str] * 3
grades = [str] * 3

for i in range(3):
    names[i] = input("Enter pupil " + str(i+1) + " name: ")
    grades[i] = input("Enter pupil " + str(i+1) + " grade: ")
    print()  # blank line for spacing

print("Test Results")
for i in range(3):
    print(names[i] + " achieved grade " + grades[i])


	
# Create two arrays of fixed size 3 to store names and grades
names = [str] * 3
grades = [str] * 3

# Loop 3 times to get input for each pupil
for i in range(3):
    # Ask for pupil name at the current position
    names[i] = input("Enter pupil " + str(i+1) + " name: ")
    # Ask for pupil grade at the current position
    grades[i] = input("Enter pupil " + str(i+1) + " grade: ")
    # Print a blank line for spacing
    print()

# Display results after all input is collected
print("Test Results")

# Loop again to display each pupil with their grade
for i in range(3):
    print(names[i] + " achieved grade " + grades[i])

Extension

Add a third array (e.g. classes = [“1A”,”1B”,”1A”]) and display all three values on each line.

Test Results
Jane in class 1B3 achieved grade A
John in class 1S1 achieved grade B
Jess in class 1A4 achieved grade C
