Write a C++ program that requires the user to type in an integer M and computes the function y(M) which is defined by y(0)=2, y(1)=1, y(m+1)=y(m)+2*y(m-1).

Expert Solution

Solution:

#include<iostream>

using namespace std;

int y(int M)

{

if(M==0)

return 2;

else if(M==1)

return 1;

else

return y(M-1)-2*y(M-2);

}

int main()

{

int M,ans;

cout<<"Enter a value for M: ";

cin>>M;

ans=y(M);

cout<<"The value of y(m) = "<<ans<<endl;

return 0;

}

Write a program that prompts the user to enter a positive integer and then computes the equivalent binary number and outputs it. The program should consist of 3 files. dec2bin.c that has function dec2bin() implementation to return char array corresponding to binary number. dec2bin.h header file that has function prototype for dec2bin() function dec2binconv.c file with main function that calls dec2bin and print results. This is what i have so far. Im doing this in unix. All the files compiled...

Write a C++ program, falling.cpp, that inputs a distance in meters from the user and computes the amount of time for the object falling from that distance to hit the ground and the velocity of the object just before impact. Air resistance is discounted (assumed to fall in a vacuum). To compute the time, use the formula: t = Square Root (2d / g) where d is the distance in meters and g is the acceleration due to gravity on...

in C++ programing language Write a program that prompts the user for an integer, then prints all of the numbers from one to that integer, separated by spaces. Use a loop to print the numbers. But for multiples of three, print "Fizz" instead of the number, and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Drop to a new line after printing each 20 numbers. If the user typed...

c++ Write a program that will ask the user for three pairs of integer values. The program will then display whether the first number of the pair is multiple of the second. The actual work of making the determination will be performed by a function called IsMultiple that takes two integer arguments (say, x and y). The function will return a Boolean result of whether x is a multiple of y.

Write a program that asks the user to type in two integer values. Test these two numbers to determine whether the first is evenly divisible by the second and then display the appropriate message to the terminal. Objective C

Include<stdio.h> In C program Write a program that prompts the user to enter an integer value. The program should then output a message saying whether the number is positive, negative, or zero.

Write a C++ program that accepts a single integer value entered by user. If the value entered is less than one the program prints nothing. If the user enters a positive integer n. The program prints n x n box drawn with * characters. If the user enters 1 , for example the program prints *. If the user enter a 2, it prints ** ** that is , a 2x2 box of * symbols.

Write a C++ program which prompts the user to enter an integer value, stores it into...

Write a C++ program which prompts the user to enter an integer value, stores it into a variable called ‘num’, evaluates the following expressions and displays results on screen. num+5, num-3, (num+3) – 2, ((num+5)*2 / (num+3)) For performing addition and subtraction, you are allowed to use ONLY the increment and decrement operators (both prefixing and postfixing are allowed). You must remember that using increment/decrement operators changes the original value of a number. Indent your code and include comments for...

Write a C++ program that prompts the user (or “Player 1”) to input an integer value between 1 and 3 (where 1=paper, 2=scissor, and 3=rock). This input should be passed into a string function called player_RPS(), and returns a string value indicating the selection of paper, scissors, or rock (as mentioned above). Next, the returned string value, along with a generated input from the computer, should be passed into a void function called RPS_comparison(), and determines whether the user’s input...

• Write a C++ program that asks the user to input two integer values, then calls a void function "swap" to swap the values for the first and second variable. • As we mentioned before, in order to swap the valors of two variables, one can use the following: temp= variable1; variable1 = variable2; variable2 = temp; • Display the two variables before you call swap and after you call that function. Comment in code would be greatly appreciated to...
