typedef is used to define your own data type in a program. Like you define a structure variable named myStruct then after executing the command
typedef myStruct m
now you can use m to define other structures with same properties and components as the myStruct variable. we define
int a
and a can be assigned the value of an integer.
similarly
m myStruct2.
