Introduction to Structures in C++ language :

C language Structure (.) Operator or sizeof() - Structures are one of the two important building blocks in the understanding of classes and objects. A structure is a collection of data while a class is a collection of data and functions. In other words, we can say, a structure plus related functions make a class. Technically, there is no difference between a structure and a class. The keyword struct tells the compiler that a structure is begin defined.

Example :

/* Description: store students name in C++ language */ #include<iostream> using namespace std; struct data{ char name[20]; }info[21]; int main() { int i,j; cout<<" Enter how many student data you want to load ( MAX 20 ): "; cin>>i; for(j=1;j<=i;j++) { cout<<"\n No. "<&l<j <<" Student name : "; cin>>info[j].name; } cout<< "\n ------ DATA STOR COMPLETED ------- \n\n"; for(j=1;j<=i;j++) { cout<<"\n No. "<&l<j <<" Name: " <<info[j].name; } }
