Pre-Structs

Here is a program that sets us up with a situation where structs can be handy:

/*
 * prestructs1.c

 *  An example leading into using structs in C, along with arrays.

 * To compile: gcc -o prestructs1 prestructs1.c

        int age1, age2;
        float height1, height2;

        printf("Person 1 of 2:\n");
        printf("==============\n");
 
        // prompt for name (string)
