Introduction
⮚ Our variables until now
⮚ Single variable
int i, char c, float f
⮚ Set of same type elements: Array
int a[10], char c[20]


⮚ If data are not same type, but related?
⮚ Example: Information about students
⮚ Student Name
⮚ Student Family Name
⮚ Student Number
⮚ Student Grade

⮚ char st_fam_name[20]
;
⮚ int id;
⮚ int grade;
⮚2- Put them altogether, they are related
⮚Use struct
