}
struct student
int exam_no, lang, eng, phy, chem, mat, csc, total;
char name [15];
}
int main()
{
students [20];
for (int i = 0; i <20; i++)
{
cout<<"\n Enter the exam number of student:"";
cin>> s[i].exam_no.;
cout << "\n Enter language names:";
ein>>s[i].lang;
cout<<"Enter name of the Student:"";
cin>>s[i].Name;
}
for (int i=0; i<20; i++)
{
if (s[i],name[0] == 's')
{
cout << "Exam number:" << s[i].name;
cout << "Student Exam number";
}
}
return 0;}

(i) A structure variable can be passed to a function in a similar way of passing any argument that is of built-in data type.
(ii) if the structure itself is an argument, then it is called "call by value".
(iii) If the reference of the structure is passed as an argument then it is called, "call by reference".

#include< iostream >
using namespace std;
int main()
{
char name[20];
cout << "Enter your name'' << endl;
cin.get(name,20);
cout << "Your name:" << name«endl;
return 0;
}
output:
Enter your name : xxxx xxxx
Your name: xxxx xxxx

An array of strings is a two-dimensional character array. The size of the first index (rows) denotes the number of strings and the size of the second index (columns) denotes the maximum length of each string. Usually, array of strings are declared in such a way to accommodate the null character at the end of each string. For example, the 2-D array has the declaration:
char Name[7][10];
In the above declaration,
No. of rows = 7;
No. of columns = 10;
we can store 7 strings each of maximum length 10 characters.

"An array is a collection of variables of the same type that are referenced by a common name".
An array is also a derived datatype in C++.
There are different types of arrays used in C++. They are:
1. One-dimensional arrays
2. Two-dimensional arrays
3. Multi-dimensional arrays
