- Using functions, develop a full C++ structured program that asks the user for hischoics:1 or 2. If the choice is 1, then your program will convert the entered Fahrenheit(F°) temperature to Celsius (C°). If the choice is 2, then your program will convert theentered Celsius (C°) temperature to Fahrenheit (F°). use the following functions:- getTemp: read the temperature from the user- getChoice: read the user choice: 1 or 2NOTE: only 1 or 2 are allowed, if not, then give anerror message warning for three times, then exit the wholeprogram with a message if the problem persists.- convertToF: converts Celsius to Fahrenheit F°= (9/5) * C° + 32- convertToC: converts Fahrenheit to Celsius C°= (5/9) * (F° - 32)Use C++ Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. Positions 0-4 of coinVals should contain the number of dollars, quarters, dimes, nickels, and pennies, respectively.void ExactChange(int userTotal, vector<int>& coinVals)Using functions, develop a full C++ structured program that asks the user for his choics:1 or 2. If the choice is 1, then your program will convert the entered Fahrenheit (F°) temperature to Celsius (C°). If the choice is 2, then your program will convert the entered Celsius (C°) temperature to Fahrenheit (F°). use the following functions: - getTemp: read the temperature from the user - getChoice: read the user choice: 1 or 2 NOTE: only 1 or 2 are allowed, if not, then give an error message warning for three times, then exit the whole program with a message if the problem persists. - convertToF: converts Celsius to Fahrenheit F°= (9/5) * C° + 32 - convertToC: converts Fahrenheit to Celsius C°= (5/9) * (F° - 32)
- Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows:dB= log10P2/P1Where P2 is the power level being measured, and P1 is some reference power level. Write a c++ programe contain function that calculates the level. The function’s prototype is as follows:double dBCalculator (double P1, double P2);Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.DO IT WITH C++ PROGRAM 1. Write a parameter and return program that will require the user to enter a temperature in Celsius and convert it to degree Fahrenheit and degree Formula: Fahrenheit = (9/5) * Celsius + 32 Kelvin = Celsius + 273 2. Refer to No. 1, transform the program using function header and function 3. Write a global and local variable program that would require the user to input a value of the Radius of a circle and then show the output in the diameter, circumference of the circle and area of the circle.Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
- 3.Create a C++ function to take input an integer parameter n and return whether the number is a power of 2 or not. bool checkPowerof2(int n) { // Return true if n is power of 2 }Q13/ Write a program in c++ that asks the user to input two numbers. If the first number entered is greater than the second number, the program should print the message: "The first number is greater." Otherwise, it should print the message: "The first number is smaller." .By using functionscan someone help me with this problem in C++ A character value (a letter from the English alphabet) A string value (string consisting of only English letters and spaces) Write a C++ program using functions to print the numbers of times the character appears in the string. The character to check in the string is case-sensitive (i.e. checking for an uppercase ‘A’ is different that checking for a lowercase ‘a’). Your solution must follow the requirements presented below: a) Do not use cout to print a message before reading the input from STDIN. b) Read the input in the main function. Note that the string value may contain spaces. c) Write a function that returns the number of times the character appears in the string. You can assume that the input from STDIN will always be valid. Input Output C Computer Science 1 this is the code I have so far #include <iostream> #include <string> using namespace std; // Write a function that returns the number of times the…
- Q. Write a function days_in_month() that returns the number of days in a month. The function has the following prototype: int days_in_month(int month, int is_leap); Month should be an integer value between 1 and 12. The function should return (-1) if an invalid month is input. The variable ‘is_leap’ is 1 for leap years, 0 otherwise. Write program in c.Q1: Write a C++ program to read any integer number and determine if the number is not prime using function int prime(), the answer will be printed from the main function.i am having problems making my program works. the following is what I have to do and underneath it is my program which I cant get it to work. i am not sure what my problem is. if you can figure it out that would be great thanks!! Write a C++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Your program should have and use at least the following functions: (a) Write a function getDate that prompts a user to enter a date as a string and returns it. (b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers. (Hint: you can use the function isdigit(c) that returns true if c is a digit character and false otherwise.) (c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int. (Hint: to convert a digit character to a digit number use static cast (’d’) - static cast(’0’) where d is 0, 1, ..., 9) (d) Write a…
