(Rounding Numbers) Function floor may be used to round a number to a specific decimalplace. The statementy = floor(x * 10 + .5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + .5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Writea program that defines four functions to round a number x in various waysa) roundToInteger(number)b) roundToTenths(number)c) roundToHundreths(number)d) roundToThousandths(number)For each value read, your program should print the original value, the number rounded to thenearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth, and the number rounded to the nearest thousandth.

(Distance Between Points) Write a function distance that calculates the distance betweentwo points (x1, y1) and (x2, y2). All numbers and return values should be of type double.

(Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b ≠ 0. Your program must be menu driven, allowing the user to select the operation (+, –, *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions: Function menu: This function informs the user about the program’s purpose, explains how to enter data, and allows the user to select the operation. Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the…

(Sort three numbers) Write the following function to display three numbers in increasing order: def displaySortedNumbers(num1, num2, num3): Write a test program that prompts the user to enter three numbers and invokes the function to display them in increasing order. Here are some sample runs:

(Python)Write a function that receives an integer. The function must return a string containing thehexadecimal representation of the integer.

(Find the Minimum) Write a function that returns the smallest of three floating-pointnumbers.

(Replace strings) Write the following function that replaces the occurrence of a substring old_substring with a new substring new_substring in the string s. The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings (string& s, const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old string, and new_string, and display the replaced string.

( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the…

(Guess the Number Modification) Modify the program of Exercise 5.32 to count the number of guesses the player makes. If the number is 10 or fewer, print Either you know the secret oryou got lucky! If the player guesses the number in 10 tries, then print Ahah! You know the secret!If the player makes more than 10 guesses, then print You should be able to do better! Why shouldit take no more than 10 guesses? Well, with each “good guess” the player should be able to eliminatehalf of the numbers. Now show why any number 1 to 1000 can be guessed in 10 or fewer tries.
