In this method, the smallest item in a given series of n elements is found and is placed in the first position. Then the smallest item from the remaining (n-l) elements is found and is placed in the second position and so on. This method requires (n-l) passes for arranging n elements.

A structure can be used in a program only if memory is allocated to it. The structure definition informs the compiler about the type and the number of data members in the structures. However, it does not allocate any memory for the structure. To use a structure in a program efficiently, a structure variable needs to be declared. The syntax for declaring a structure variable is

Both the structures and unions are syntactically and functionally same, however, they differ in the way memory is allocated to their members. While declaring structure variables, the different members are stored in different, although, adjacent memory locations whereas different members of a union variable share the same memory location. The amount of memory sufficient to hold the largest member of a union is allocated to a union variable. Thus, a union enables the same block of memory to store variable of one type at one time and of different type at another time. To understand the concept of memory allocation to a union, consider these statements.

Like arrays, structures are also used to store a list of data items in a single variable. However, these data items may be of different data types. Structures are used whenever a programmer requires binding the same or different types of related data items together into a single entity.
