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.

Driving 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)

- using void functions 1. Complete the program shown below. Note: do not omit the comments a) You will write a void function to get a positive integer between 1 and 12 inclusive. The twelve numbers represent the months of the year. The user will be asked to enter an integer between 1 and 12 inclusive. If the number entered by the user is not within range, an appropriate error message will be displayed, and the user will be asked to try again until a valid number is entered. b) You will write a void function to print the month number and the month name with an appropriate message. Consider a good layout when displaying the output. c) You will also complete the function main by making a call to the function GetMonthNumber with an appropriate argument and by making a call to the function DisplayMonth with an appropriate argument d) Add a loop to allow the program to repeat, allowing the user to continue.

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.
