the Arduino/C++ program to implement the following: Write • Use the Serial Monitor to retrieve an input number, using Serial.available () and Serial.parseInt() • Use an if-else (or a variation of it) to check whether the number is odd or even. A useful C++ operator to use for this is the "modulo" which uses the % symbol. This operation returns the remainder of the division. For example, x % 2 will return a 0 if the value x contains an even number (i.e. x%2 == 0 will be TRUE). • Use the Serial Monitor to output the messages "Your input number is odd." or "Your input number is even." depending on whether the input is odd or even.

Please help me in C++ I just need help with my ceasar cipher and decipher function please help

write this in c++ format function sequence(n){    var n = 10; // this is just for explanation you can take any value from user input  var arr = [n]; //this is to store result    //Continue to generate numbers in this way until N becomes equal to 1  while(n > 1){      //check if even   if(n % 2 == 0){    //If N is an even number, then divide N by two to get a new value for N    n = n / 2;   }  else{      //If N is an odd number, then multiply N by 3 and add 1 to get a new value for N.   n = (n * 3) + 1;  }    arr.push(n);  }  Logger.log("sequesnce: "+ arr)  Logger.log("Number of terms: "+arr.length);}

Write a C++ function named dup that makes a copy of a user input C-string and repeats the C-string. For example, if the user inputs "HelloWorld" then it will say "HelloWorldHelloWorld" Dynamically allocate memory *(using new)* for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character!   Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you wish, but you are not required to. Please demonstrate calling this function.   Example: dup("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "GiantsGiants" char* dup(char *str)

Write a simple calculator program in C++. Your program should: read in the operator symbol (+, -, *, /) as a char read in two decimal numbers (type double) output the result of performing the requested operation on the given numbers format the output as in the given example HINT: Use a switch statement instead of conditionals. For example: Input Result + 5.5 2.01 5.5 + 2.01 = 7.51

Write a complete C++ program that prints the change in population of the the United States: p = p + Bp Dp where p is the population, B is the birth rate of 12.4 births for every 1000 people (12.4/1000) each year, and D is the death rate of 8.4 for every 1000 people (8.4/1000). In 2017, the population of United States was 325.7 million. Your program should ask the user for the number of years and print expected population over those years starting from 2017. Each line should have: the year and the population (in millions). A sample run: Please enter the number of years: 10 Year 2017 325.70 Year 2018 327.00 Year 2019 328.31 Year 2020 329.62 Year 2021 330.94 Year 2022 332.27 Year 2023 333.60 Year 2024 334.93 Year 2025 336.27 Year 2026 337.61
