Homework 7 - Using a Static Local Variable
===================================================================

.. seealso:: :ref:`storage_class`

Write a C program that uses a function with a static (storage class)
local variable to print out an asterisk character (\*) and a space character
for each time it was called.  For example, the following loop would print the
output shown below it. 

::

    #include <stdio.h>
    void howmany( void );

    int main(void) // This is all that is needed in main.
    {
        int i;
        
        for(i = 0; i < 3; i++)
            howmany();
        return 0;
    }
