Structure
Structure is used for creating user defined data type. A structure gathers together different-different data type into a single entity. Using structure we can create a data type which can store some different type of value into a single variable. Draw back of variable is, it only stores one value at a time. C provides a structure which is used to create structure. The keyword is "struct".
Creating Structure in C:-
struct stu
{
int r;
char n[20];
};
Few important point about structure:-
1- We use . (Period) operator to access member of structure.
2- We use -> to access member of structure through pointer.
3- Structure can be nested but can't contain itself variables.
4- Structure can contain itself pointer.
