Rewrite the given program to follow these instructions:  The program in the Programming Example: Fibonacci Number does not check: Whether the first number entered by the user is less than or equal to the second number and whether both the numbers are nonnegative. Whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things. the program:  //************************************************************* // Author: D.S. Malik // // Program: nth Fibonacci number // Given the first two numbers of a Fibonacci sequence, this // determines and outputs the desired number of the Fibonacci // sequence. //************************************************************* #include using namespace std; int main() { //Declare variables int previous1; int previous2; int current; int counter; int nthFibonacci; cout << "Enter the first two Fibonacci numbers: "; //Step 1 cin >> previous1 >> previous2; //Step 2 cout << endl; cout << "The first two Fibonacci numbers are " << previous1 << " and " << previous2 << endl; //Step 3 cout << "Enter the position of the desired Fibonacci number: " ; //Step 4 cin >> nthFibonacci; //Step 5 cout << endl; if (nthFibonacci == 1) //Step 6.a current = previous1; else if (nthFibonacci == 2) //Step 6.b current = previous2; else //Step 6.c { counter = 3; //Steps 6.c.2 – 6.c.5 while (counter <= nthFibonacci) { current = previous2 + previous1; previous1 = previous2; previous2 = current; counter++; }//end while }//end else   /* Output the Fibonacci number at nth position */ return 0; }//end main

Write  Algorithm  for a program that asks the user to enter two numbers. Then ask the user to enter  1 to add these numbers or 2 to multiply these numbers

Write an algorithm that asks the user to enter 10 test scores and do the following:(a) Print out the highest and lowest scores.(b) Print out the average of the scores.(c) Print out the second largest score.(d) If any of the scores is greater than 100, then after all the scores have been entered, print a message warning the user that a value over 100 has been entered.(e) Drop the two lowest scores and print out the average of the rest of them.

The correct statements are: (ab)*a = a(ba)* (a U b)* b (a U b)* = a*b (a U b)* (a U b)* ba (a U b)* U a*b* = (a U b)* □ (a U b)* b (a U b)* U (a U b)* a (a U b)* = (a U b)*
