In C++
- Consider the following recursive function (Chapter 17, #9, modified)
void recFun(int x)
{
if (x > 10)
{
recFun(x / 10);
cout<< x % 10;
}
else
cout<< x;
}
How can the code be modified so that the sum of all digits is printed?
Step by step
Solved in 2 steps
- In C programing Write a recursive function that returns the product of the digits of its integer input parameter, n. You may assume that n is non-negative. For example, productDigits(243) should return 24, since 2 x 4 x 3 = 24.int productDigits (int n) {in c++ Convert the following function to one that uses recursion. void sign(int n) { while (n > 0) cout << "No Parking\n"; n--; } Demonstrate the function with a driver programConsider the following recursive function. What does it calculate in terms of x, y, and z? 01: Private Function CalcRecurse(ByVal x As Integer, ByVal y As Integer, ByVal z As Integer) As Integer 02: If x <= 1 Then 'Assume that CalcRecurse always starts with x > 1 03: Return y 04: Else 05: Return z + CalcRecurse(x - 1, y, z) 06: End If 07: End Function
- In C++ Write a recursive function that displays a string reversely on the console using the following header:void reverseDisplay(const string& s) For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.Write a recursive function diff which takes two positive integer arguments (x and y) and returns |x – y|. You may not perform an x - y calculation anywhere in the function! Example calls: diff(3, 7) returns 4; diff(7,3) returns 4 In JAVAProblem: Recursive Power Method Design a python function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output. Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00
- 2. Write a recursive function printNum()that prints any given number by putting spaces between successive characters to be printed. For example: printNum (12) prints 1 2 printNum (327) prints 3 2 7 printNum (-912) prints - 912 Programming Language :- Cin c++ The Fibonacci number is the one in which each number is the sum of the two precedingnumbers. An example is shown below:0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...Write a recursive function that prints the first fifteen Fibonacci numbers. Your functionmust be recursive. Note that the first three Fibonacci numbers are 0, 1, 1, but after that ,the Fibonacci number is n = n - 1 + n - 2. Note that you will write only a function.Recursive Exponentiation (using c language) Write a recursive function power(base, exponent) that when invoked returns baseexponent. For example, power(3, 4) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than or equal to 1. Then, write a demo program that uses the power function and test it out for a number of inputs. Hint: The recursion step would use the relationship baseexponent = base * baseexponent–1 and the terminating condition occurs when exponent is equal to 1 because base1 = base
- Write a recursive function (no auxiliary functions, for/while loops, STL containers or functions, static/global variables) int productDigits(unsigned int n); Given an integer n, multiply up all the digits in the number and return the product. productDigits ( 234); productDigits(118); productDigits(52892); // returns 24 // returns 8 (1*1*8) // returns 1440 (5*2*8*9*2) (2*3*4) Edit View Insert Format Tools Table 12pt v Paragraph В I U A ...The function ver() is defined as follows: void ver(char "pc) { char c; if( "pc == "\O' ) return; c = "pc; ++pc; ver(pc); putchar(c); Show the output when function ver() is called as follows: ver("recursion");2) Consider a recursive function to find the maximum value in an array of integers. The function declaration is: int maxValue( int vals[], int size, int start ); For this function, we need to know the size of the array and the starting index of the array (because both will change when a recursive call is made). You may assume that there is at least one value in the array. C++ language
