Just as arrays of basic types such as integers and floats are allowed in
C, so are arrays of structures. An array of structures is declared in
the usual way:
struct personal_data my_struct_array[100];
The members of the structures in the array are then accessed by
statements such as the following:
The value of a member of a structure in an array can be assigned to
another variable, or the value of a variable can be assigned to a
member. For example, the following code assigns the number 1965 to the
year_of_birth member of the fourth element of
my_struct_array:
my_struct_array[3].year_of_birth = 1965;
(Like all other arrays in C, struct arrays start their numbering
at zero.)
The following code assigns the value of the year_of_birth member
of the fourth element of my_struct_array to the variable
yob:
yob = my_struct_array[3].year_of_birth;
Finally, the following example assigns the values of all the members of
the second element of my_struct_array, namely
my_struct_array[1], to the third element, so
my_struct_array[2] takes the overall value of
my_struct_array[1].
