Array of Structure

Structure is collection of different data type. An object of structure represents a single record in memory, if we want more than one record of structure type, we have to create an array of structure or object. As we know, an array is a collection of similar type, therefore an array can be of structure type.

Syntax for declaring structure array

              struct struct-name
              {
                     datatype var1;
                     datatype var2;
                     - - - - - - - - - -
                     - - - - - - - - - -
                     datatype varN;
              };

              struct struct-name obj [ size ];

Example for declaring structure array

       #include<stdio.h>

       struct Employee
       {
              int Id;
              char Name[25];
              int Age;
              long Salary;
       };

       void main()
       {
              int i;
              struct Employee Emp[ 3 ];         //Statement   1

              for(i=0;i<3;i++)
              {

              printf("\nEnter details of %d Employee",i+1);

                    printf("\n\tEnter Employee Id : ");
                    scanf("%d",&Emp[i].Id);

                    printf("\n\tEnter Employee Name : ");
                    scanf("%s",&Emp[i].Name);

                    printf("\n\tEnter Employee Age : ");
                    scanf("%d",&Emp[i].Age);

                    printf("\n\tEnter Employee Salary : ");
                    scanf("%ld",&Emp[i].Salary);
              }

              printf("\nDetails of Employees");
              for(i=0;i<3;i++)
              printf("\n%d\t%s\t%d\t%ld",Emp[i].Id,Emp[i].Name,Emp[i].Age,Emp[i].Salary);

       }
