A structure that allows repeated execution of a block of statements is a(n) _____________.
- sequence
- selection
- array
- loop
To find the correct option that allows the repeated execution of a block of statements.
d) loop
Explanation of Solution
Explanation: A loop is a structure. It contains one or more than one Boolean expression within the parentheses that returns true or false. The loop body contains a block of statements within the curly braces. If a loop body contains a single statement then it can be written without the use of curly braces. When the Boolean expression of the looping structure returns true then the body of the loop executes. After every iteration (one execution of the loop), the Boolean expression of the looping structure evaluates again. If the Boolean expression of the looping structure returns the true value, the loop body executes again and the Boolean expression of the looping structure Re-evaluated. When the Boolean expression of the looping structure returns the false value, the execution of the loop stopped.
Conclusion: A loop structure allows the repeated execution of a block of statements.

- LargeSmall.py - This program calculates the largest and smallest of three integer values. # Declare and initialize variables here largest = None smallest = None # Prompt the user to enter 3 integer values # Write assignments, and necessary if else statements here as appropriate # Output largest and smallest number. print("The largest value is " + str(largest)) print("The smallest value is " + str(smallest))arrow_forwardCreate the following program: In this question you are asked to write a lottery game application. Your program must first display a welcome message/banner asking the human player for his/her given name. Generate a random number between 0 and 999, which you are to store in a single variable (int). Allow the user to guess a three digit number between 0 and 999, which you are also to store in a single variable of type int. Compare the user’s guess to the random number and display a message that includes the user’s name, user’s guess, the randomly determined three-digit number and the amount of money the user has won as follows: Matching digits Awards Any one matching. $10 Two matching. $100 Three matching not in order. $1000 Three matching in exact order. $1,000,000 No matches. $0 Make sure that your application accommodates repeated…arrow_forwardC++ Visual 2019 A particular talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses this method to calculate a contestant's score. It should include the following functions: void getJudgeData() should ask the user for a judge's score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. void calcScore() should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores. The last two functions, described below, should be called by calcScore, which uses the returned information to determine which of the…arrow_forward
- In Python, use only some or all of the following concepts: decision structures, repetition structures, functions, and files. Write a program that reads five test scores from a file called "grades.txt". The program should display a letter grade for each score and the average test score. Write the following functions in the program: grade_average. This function should accept five test scores as arguments and return the average of the scores. letter_grade. This function should accept a test score as an argument and return a letter grade for the score based on the following grading scale: Score Letter Grade 90 - 100 A 80 - 89 B 70 - 79 C 60 - 69 D Below 60 F The grades.txt file should test all possible grades.arrow_forwardThe program contains errors; it will therefore not run.
