Concept explainers
Assume the following variables are defined:
int age;
double pay;
char section;
Write a single cin statement that will read input into each of these variables.
Explanation of Solution
“cin” statement:
“cin” is the standard input stream that is used together with the extraction operator “>>” to process the formatted input.
Syntax:
Syntax to read input by using “cin” statement:
cin >> variable1 >> variable2;
- In the above statement, “cin” is a predefined keyword and “variable” is the name of the variable to read value from the user.
Single “cin” statement to read input:
/* input statement to get three input using single line */
cin >> age >> pay >> section;
The above statement is used to get three inputs “age”, “pay” and “section” from the user by using a single “cin” statement.

- Lowest Score Drop Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.arrow_forwardA program contains the following function. int cube(int num) {return num * num * num; }Write a statement that passes the value 4 to this function and assigns its return value to the variable result.arrow_forwardVoid functions do not return any value when they are called.True or falsearrow_forward
- User Defined Function: Void Function Create a JAVA program that will add, subtract, multiply and divide two numbers. Use user defined function for each operator Any number divided by zero will result to undefined Use int or double data type only for all variables declaredEXPECTED OUTPUT: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_forwardint numFeet, numInches; int totalinches -52; //total number of inches //number of feet // number of inches Write the statements to convert the total number of inches to feet and inches: a) Calculate the number of feet, and store the result in numFeet. b) Calculate the remaining number of inches, store the result in numlnches.arrow_forward
- Test Average and Grade Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Write the following functions in the program: • calc_average-This function should accept five test scores as arguments and return the average of the scores. • determine_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 60-69 D Below 60 F A sample run is as follows: Enter test score 1: 75.0 Enter test score 2: 95.0 Enter test score 3: 80.0 Enter test score 4: 90.0 Enter test score 5: 85.0 Your grades are as follows: Test 1: C Test 2: A Test 3: B Test 4: A Test 5 : Barrow_forwardT F A variable must be defined before it can be used.arrow_forwardThe following declaration, program, and program segment has errors.

- c++ Write a function that returns a float value. The function will check the users entry. It will return a float value which is between 0 and 100 and is divisible by 17 If entered value is not a float, display “Error!!! Not a number”. If the number is out of range display “Error!!! Outside the range”. If the number is not between the range, the users will be prompted to enter another number. It will return only a valid numberarrow_forwardDriving costs - functions Learning Objectives Create a function to match the specifications Use floating-point value division Instructions Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') Ex: If the input to your program is: 20.0 3.1599 the output is: The gas cost for 10 miles is $1.58 The gas cost for 50 miles is $7.90 The gas cost for 400 miles is $63.20 Your program must define and call the driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should…arrow_forwardRelated to R code. Question: Write a function called temp_categorizer that takes one argument ‘temperature’ and returns the following: - a value of “hot” if temperature is greater or equal to 90 - a value of "warm" if temperature is greater than 60 but less than 90 - a value of "cold" if temperature is more than 32 but less than 60 - a value of "freezing" if temperature is 32 or below And also Use the following vector for problem number : sentence <- c("Learning", "loops", "in", "R", "is", "not", "that", "bad") Create a loop that: loops over the range of possible word lengths displays a message detailing the words that match the length For example: at length 8, the loop should state that the word "Learning" has 8 letters Hints: Use the function nchar() which gives the number of letters in each word. • Example: try nchar(sentence) min() and max() may help you specify a rangearrow_forward
