Types of Function

A function is a process or task that does some operation in the program. Some programming languages may contain built-in functions for certain commonly used tasks. Most programming languages also support user-defined functions, which means a user can write their own function to perform some operation. There are some libraries or header files that contain built-in functions for performing certain tasks.

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 range

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.
Complete the following program When a machine reads blood pressure from a human body it displays two numbers they are called Systolic and Diastolic pressures.

Program consists of two functions as follows. vold input .: This function is with two pass by reference parameters, and it reads input from the user. string process( .): It receives two numbers(systolic and diastolic) and then it determines and returns a category according to the table below. Diastolic and 60 to 80 and 80 to 90 Category Systolic Normal 80 to 120 Elevated 120 to 139 High blood equal and pressure above 140 above 90 or
