What's The Output?

100

#include <iostream>

using namespace std; 

int main() {

  bool itIsFriday = true;

  cout << itIsFriday << endl;

  return 0; 

}

Output: 1

// remember that for boolean variables, the 1's and 0's represent true (1) and false (0) values. Therefore, printing 1 means yes! It is Friday :)

#include <iostream>

using namespace std;

int main() {

  char letter = 'a';

 while (letter <= 'z') {

   cout << letter << " ";

   letter = letter + 1;

 }

 return 0;

}

Output: 

a, b, c, d, e, f, g, ... x, y, z

// looping through while adding a plus one to a letter value will print out the following letter.

#include <iostream>

using namespace std; 

int main() {

  

  int n = 1; 

  while (n <= 5) {

    

    if (n == 5) {

      cout << n; 

    } else {

      cout << n << ", "; 

    }

    

    n = n + 1; 

  }

  

  return 0; 

}

Output: 1, 2, 3, 4, 5

// remember you can use an if statement inside of a while loop to ensure that the last comma won't get printed

#include <iostream>

using namespace std; 

int main() {

  

  char val = 'c'; 

  val = val + 4; 

  cout << val << endl; 

  

  return 0; 

}

#include <iostream>

using namespace std; 

int main() {

  

  char val = 'c'; 

  val = val + 4; 

  cout << val << endl; 

  

  return 0; 

}

Output: g 

// the ASCII value of the letter adds to whatever value you added on

#include <iostream>

using namespace std; 

int main() {

  int x = 5; 

  if (x > 4 || x < 7 && x != 5) {

    cout << "Hurrah" << endl; 

  } else {

    cout << "boo" << endl; 

  }

  return 0; 

}

Output: Hurrah

// remember the order of operations when it comes to if statements and the use of || and &&
