- A specific class of C++ variable is a pointer variable. Do you understand how to utilize it?struct date{ int day; int month; int year; }; Write a function named void increaseDay(struct date *d) that increases the value of a variable of struct date type with integer year, month, and day members by one day. Write a function named void decreaseDay(struct date *d) that decreases the value of a variable of struct date type with integer year, month, and day members by one day. Write a C program that reads from the user a date in d/m/y format and the amount of increase or decrease as an integer. Display the new date in d/m/y format. You may call related functions as many as given increase or decrease value. Note 1: You do not need to consider leap years. Use always 28 days for month February. Note 2: Do not modify the function prototypes. Sample Input1: Sample Output1: 12/8/1990 -5 7/8/1990 Sample Input2: Sample Output2: 26/2/2005 5 3/3/2005 Sample Input3: Sample Output3: 29/12/1998 7 5/1/1999…When invoking a function that takes several arguments, does the order in which the parameters are supplied matter?

- C ++ - Create a program that calculates the distance an object travels in meters on Earth for a specific number of seconds. Also calculate the distance traveled on the moon, also in meters, for a specific number of seconds. Do not include any global variables Your program must have the main function and, at least, the following four additional functions. The signatures for these functions must be as follows: double readSeconds() double calculateEarthDistance(double seconds) double calculateMoonDistance(double seconds) void displayResults(double seconds, double earthDistance, double moonDistance) The readSeconds function will be an input function that will read in a double value from cin and return that value back to main. The calculateEarthDistance function will calculate the distance an object falls (on Earth) during the specified number of seconds. The calculateMoonDistance function will calculate the distance an object falls (on the Moon) during the specified number of seconds. The…In C++ what is the effect of the const keyword in the following statement? int* const intPtr = new intConsider the following recursive function. What does it calculate in terms of x, y, and z?

- Instructions: In Basic C Language In the code editor, you are provided with a main function that asks the user for an integer input and passes this value to a function called, getFactorial() The getFactorial() function has the following description: Return type - int Name - getFactorial Parameters - one integer Description - returns the factorial of the passed integer Your implementation should be RECURSIVE and you should not use any loops Input #include<stdio.h> int getFactorial(int); int main(void) { int n; printf("Enter n: "); scanf("%d", &n); printf("Factorial of %d is %d", n, getFactorial(n)); return 0;} int getFactorial(int n) { // TODO: Implement this recursive function} Output should be: Enter n: 3 Factorial of 3 is 6In C++ Write a function header ( and only function header ) for the following: Function named printArray() that returns nothing, and that takes two parameters: an array of integers named testScores [ ] an integer named SIZE .Write a console application that initializes at least five (5) variables or constants with different data types, then display their values. Provide a meaningful identifier of the variables or constants. Name the namespace as DataTypeApp and its class as DataTypeProgram.
- Write a program in C++ that: Declares a variable suitable for holding a person’s name Prompts the user to enter a person’s name with the text Enter name: Reads the user's input and stores it in the variable created in step 1 Outputs the following information about the name they entereda. The index of the first character of the last nameb. The first 3 characters of the first namec. The last 3 characters of the last nameYour output should look like the examples below. **Note: Your code should account for the fact that the user might enter a middle name or initial. Example 1: Enter name: Grace Hopper Index of the first character of the last name: 6 First 3 characters of the first name: Gra Last 3 characters of the last name: per Example 2: Enter name: Dorothy J. Vaughan Index of the first character of the last name: 11 First 3 characters of the first name: Dor Last 3 characters of the last name: hanC++ printSmaller is a function that accepts two int parameters and returns no value. It will print the value of the smaller one parameters. The function protoype is as follows: void printSmaller(int num1, int num2); write the statments to read two integers and call this function to display the smaller one.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.
