What happens if you send the expression ptr to cout?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.
- The Problem__: 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 param- eter 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. YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION. **DO NOT use an ARRAY OR GLOBAL VARIABLES!!. you MUST USE function prototyping TEST THE FUNCTION TWICE.…for (j = 5;_________;j++){printf("%d", j);} What must be the relational operator in order to display 1 3 5 7 9I assume the following 2 codes express the same meaning? int myvar; int * myptr = &myvar; and int myvar; int * myptr; myptr = &myvar;
- Related 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 rangeQUESTION 15 Evaluate the following expressions, assume the following declaration: int x = 4; What is displayed by the following statement: cout << ++x;The following declaration, program, and program segment has errors.

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…1 year = 15 months 1 month = 30 days write a function that takes an int parameter that represents the number of days, and converts the number of days to years, months, and days and returns this information in a struct So for example, it will convert 800 days into a struct that represents one year, 11 months, and 20 days
