C struct prototype
WebA struct is a user-defined type that can hold multiple different types of variables. A struct variable can be declared either on its own or as part of the struct definition. We access a struct property member with dot notation ( .). We access a struct pointer member with arrow notation ( ->). WebC - Structures. Arrays allow to define type of variables that can hold several data items of the same kind. Similarly structure is another user defined data type available in C that allows to combine data items of different kinds. Structures are used to represent a record. Suppose you want to keep track of your books in a library.

In the above program, three structure variables c1, c2 and the address of result is passed to the addNumbers () function. Here, result is passed by reference. WebNested Structures. You can create structures within a structure in C programming. For example, struct complex { int imag; float real; }; struct number { struct complex comp; int integers; } num1, num2; Suppose, you want to set imag of num2 variable to 11. Here's how you can do it: num2.comp.imag = 11;
