What Is a Structure?
A structure is a collection of one or more variables grouped under a single name for easy manipulation.
Each variable within a structure is called a member of the structure.

Defining and Declaring Structures
struct struct_ name
<
varname_1 : vartype_1
varname_2 : vartype_2
…
varname_n : vartype_n
>
varname : struct_name

Defining and Declaring Structures
E.g.:
Program Example
Kamus:
struct student:
<
name : string
nrp : integer
>
M : student
Algoritma:
M.name ← “Jhony”
M.nrp ← 7201001

More-Complex Structures
A structure can contain other structures.
A structure can contain one or more arrays as members.
You can also have an array of structures.

Exercises
Create a program that asks for two coordinates (coord1 and coord2}) in integer. Display the linear equation that through the coordinates in y=mx+c form.
E.g.:
The linear equation that through {1, 2} and
{5, 7} is y=1.25x + 0.75.
Note: Use a structure that hold two type integer member (x, y).

Exercises
A structure has one type integer member (NIM) and one type float member (IPK). Create a program using the structure that asks data of five students and displays data of the lowest and the highest IPK on screen.
A structured named triangle has three coordinates. Create a program that asks coordinates of a triangle and display the its circumference on screen.
