(0) three for loops, what is the output?

Check file "forLoopQuiz.c"

(0.5)  Nested statements...

If I have an "if", "for", "while" etc...
with only one statement inside, I don't
need the curly braces:

for example, the following two options
for this code work IDENTICALLY:

/* option 1 */

x = 5;
if (x < 10)
{
  printf("x is less than 10\n");
}
if (x % 2 == 0)
{
  printf("x is an even number \n");
}

/* option 2 */

x = 5;
if (x < 10)
  printf("x is less than 10\n");
if (x % 2 == 0)
  printf("x is an even number \n");

(2) for loops

We looked at forLoopDemo.c to see a few for loops
that printed lines of stars, or lines of blanks.

(3) Scope: A variable declared inside a block is 
only known inside that block.

(4) void functions with no arguments



    void printLineOfStars(void)
    {
       ....
    }


(5) void functions with no one int argument
    


    void printLineOfNStars(int n  )
    {

    }


(6) void functions with no one int argument and 
        one char argument


    void printLineOfNChars (int n , char c )
    {

    }



(7) functions that return a numeric argument


    int maxOfTwoInts(int num1, int num2)
    {
        
    }

    double celsiusToFahren(double cTemp)
    {
      
    }



Back to for loops.... while loops

Printing an empty box.
