Exercises

1. 4.11 (Correct the Code Errors) Identify and correct the error(s) in each of the following:

   1.  

      
      if (age >= 65); {
         cout << "Age is greater than or equal to 65" << endl;
      }
      else {
         cout << "Age is less than 65 << endl";
      }
      

   2.  

      
      if (age >= 65) {
         cout << "Age is greater than or equal to 65" << endl; 
      else; {
         cout << "Age is less than 65 << endl";
      }
      

   3.  

      
      unsigned int x{1};
      unsigned int total;
      
      while (x <= 10) {
         total += x;
         ++x;
      }
      

   4.  

      While (x <= 100)
         total += x;
         ++x;
      

   5. 
      while (y > 0) {
         cout << y << endl;
         ++y;
      }
      

2. 4.12 (What Does this Program Do?) What does the following program print?

   
    1   // Exercise 4.12: Mystery.cpp
    2   #include <iostream>
    3   using namespace std;
    4
    5   int main() {
    6      unsigned int x{1};
    7      unsigned int total{0};
    8
    9      while (x <= ...
