Double length is read from input and area is the square of length. Perform the following tasks: • Output length with a maximum of eight digits, showing the decimal point and any trailing Os. Then, output " ". • Output area in fixed-point notation with a maximum of five digits in the fraction. Then, output" ". • Output area in scientific notation with a maximum of five digits in the fraction. End with a newline. Ex: If the input is 6.75, then the output is: 6.7500000 45.56250 4.55625e+01 Note: cout << showpoint shows the decimal point and any trailing Os even when the fraction (after the decimal point) is zero. 1 #include 2 #include 3 using namespace std; 4 5 int main() { 6 7 8 9 10 1234 15 16 double length; double area; cin>> length; 11 area= 16 3 length* length; *Your code goes here */ return 0;

In C++ please

please code this for me in c++ using void, functions, loops, (basic c++ not complicated or highlevel please). I tried to code it myself but there are many mistakes I dont know how to fix so please write a similar one for me but it works.  The question is only 1 but it has 2 parts (2 different functions that should be in one code)       MY CODE:  #include <iostream>using namespace std; int IsPalindrome(int p);void GCD(); int main (){    int choice;    cout << "Please enter a choice: "<<endl;     cout << "Enter one for IsPalindrome "<<endl;    cout << "Enter 2 for GCD "<<endl;    cout << "Enter 3 to exit the program "<<endl;     cout << "Choice: "<<endl;     cin >> choice;            if (choice == 1)    {        int p;        cout << "Please enter a 3 digit number: "<<endl;         cin >> p; if(p%10==p/100)      {  cout<<p<<" is a palindrome " <<endl;  }  else {…

Need help figuring out this program and typing it in c++.
