Q2: Write a function in c++, reverseDigit, that takes an integer as a parameter and returns the number with its digits reversed. For example, the value of reverseDigit(12345) is 54321; the value of reverseDigit(5600) is 65; the value of reverseDigit(7008) is 8007; and the value of reverseDigit(-532) is -235.
Write a function called area circumference generator that takes a radius of a circle as a function parameter and calculates its circumference and area. Then returns these two results as a tuple and prints the results using tuple unpacking in the function call accorrding to the given format. [Must use tuple packing & unpacking] Example1: Function Call: area_circumference_generator(1) Output: (3.141592653589793, 6.283185307179586) Area of the circle is 3.141592653589793 and circumference is 6.283185307179586 ======== :===== Example2: Function Call: area_circumference_generator(1.5) Output: (7.0685834705770345, 9.42477796076938) Area of the circle is 7.0685834705770345 and circumference is 9.42477796076938
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)
In C++ Language (please use hint) : Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is samller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver (i.e. a main() invoking your function).
C++ Coding Question, Fill the void function *n1, int *n2, int *n3) void passReference(int { // Write your code here } Rounding to nearest 10 and rotating once clockwise In this coding exercise, you are asked to write the body of a function called passReference, which takes three integers by reference, round off each number to the nearest 10, and then right rotate all the numbers clockwise only once. For example, if variables a, b, and c contains the following values: a = 214; b = 2147; c=214748; Then values of variables after calling the passReference(&a, &b, &c) will be: a = 214750 b = 210 c=2150 Sample inputs 214,2147,214748 10,20,30 0,2,3 5,9,13 2147483641,2147483635,2147483631 Sample outputs 214750,210,2150 0,10,20 0,0,0 10,0,10 2147483630,2147483640,2147483630

C Programming Problem : Write a C program with a function that takes an integer value (1 <- integer value < 9999) and returns the number with its digits reversed. For example, given the number 6798, the function should return 8976. Those two- original number and reversed number- numbers will pass to another function as parameters and calculate their sum. The program should use the function reverseDigits to reverse the digits and SumOriginalReverse to calculate their sum. Your output should appear in the following format: Output reverse digiS 4321 Main Enter a number between 1 and 9999: 6798 The number with its digits reversed is: 8976 6798 + 8976 - 15774 12.34 JomoriginalRevers Enter a number between I and 9999: 6655 The number with its digits reversed is: 5566 6655 + 5566 = 12221 Enter a number between 1 and 9999: 8 The number with its digits reversed is: 8 8 + 8 = 16 Enter a number between 1 and 9999: 123 The number with its digits reversed is: 321 123 + 321 = 444 Enter a number…

Write function headers for the following:a. A function named check() that has three parameters. The first parameter should accept an integer number, and the second and third parameters should accept a double-precision number. The function returns no value.b. A function named findAbs() that accepts a double-precision number passed to it and returns its absolute value.c. A function named mult() that accepts two floating-point numbers as parameters, multiplies these two numbers, and returns the result.d. A function that produces a table of the numbers from 1 to 10, their squares, and their cubes. No arguments are to be passed to the function, and the function returns no value.e. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The function should determine and return the hypotenuse, c, of the triangle. (Hint: Use Pythagoras’ theorem, )
C Program: An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. I have written a function called isPerfect (see below), that determines whether parameter passed to the function is a perfect number. Use this function in a C program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. // isPerfect returns true if value is perfect integer, // i.e., if value is equal to sum of its factors int isPerfect(int value) { int factorSum = 1; // current sum of factors // loop through possible factor values for (int i = 2; i <= value / 2; ++i) { // if i is factor if (value % i == 0) { factorSum += i; // add to sum } } // return true if value is equal to sum of factors if (factorSum == value) { return…
