® Syntax of declaration of a variable of the structure :, , struct structure_name structure_variable_name;, For example, to declare a variable of the above defined, Structure student, we can write it as:, struct student s];, , ~— The variables declared inside the structure are called as the, member elements of the structure. For example name, roll, , number and fees are member elements of the structure, student,, , Structure is normally used when a set of data items, Corresponding to a common thing are to be stored together., For example, when information of a student is to be stored,, we need to store his name, roll number, fees etc. In this case, we can make a structure element and store the corresponding, data of every student in a Separate structure element., , To access a member element of a structure variable we use, the dot operator (““”), also called as the period operator. The, Syntax of accessing a structure element is given below:, , structure_variable_name.varaible_name;, , For example, in the above case to access the fees of the, , student “si”, the period operator will be used as shown, below:, , sl.fees;, , The concept of structure will be clear with an example., , » Program 4.1.1: Write a Program to store and display, the name, roll number and fees of a student using, , Structure. ‘, , , , , , , , , , , , , Structures an, , Explanation :, , The declaration of a Structure for student was already, discussed; the same structure is used here., , Also the declaration of a variable of structure was discussed, the variable s1 is declared here in the same manner., , ~The student’s name is Accepted using gets() function, while, other parameters using “cin”. The parameters are access!, Using the petiod operator as just discussed. Also to displ, , the variables of the structure elements we have used, , , , Write a pragram to store and displ!, Tuns Scored and wickets taken of a cricket
