# Structs Hackerrank Problem Solution

Struct is a way to combine multiple fields to represent a composite data structure, which further lays the foundation for Object Oriented Programming. For example, we can store details related to a student in a struct consisting of his age (int), first_name (string), last_name (string) and standard (int).

struct can be represented as

``````struct NewType {
type1 value1;
type2 value2;
.
.
.
typeN valueN;
};``````

You have to create a struct, named Student, representing the student’s details, as mentioned above, and store the data of a student.

Input Format

Input will consist of four lines.
The first line will contain an integer, representing age.
The second line will contain a string, consisting of lower-case Latin characters (‘a’-‘z’), representing the first_name of a student.
The third line will contain another string, consisting of lower-case Latin characters (‘a’-‘z’), representing the last_name of a student.
The fourth line will contain an integer, representing the standard of student.

Note: The number of characters in first_name and last_name will not exceed 50.

Output Format

Output will be of a single line, consisting of age, first_name, last_name and standard, each separated by one white space.

P.S.: I/O will be handled by HackerRank.

##### Solution
```#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
struct Student {
string first_name;
string last_name;
int age;
int standard;
};
/*
*/

int main() {
Student st;

cin >> st.age >> st.first_name >> st.last_name >> st.standard;
cout << st.age << " " << st.first_name << " " << st.last_name << " " << st.standard;

return 0;
}
```
```: the only difference between 'class' and 'struct' is that 'struct' has a default visibility set to public, while 'class' has a default visibility set to private.
And here's my code, we use brace-initializers (introduced in C++11) to ensure that we have an initialized structure when we intanciate one:
struct Student
{
unsigned age{};
std::string first_name{};
std::string last_name{};
unsigned standard{};
};```
