HackerRank Structs solution in c++ programming

In this HackerRank Strutus problem in c++ programming language, 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.

HackerRank Structus problem solution in c++ programming.

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

/*
    add code for struct here.
*/
struct Student
{
    unsigned age{};
    std::string first_name{};
    std::string last_name{};
    unsigned 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;
}

Second solution

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#include <string>
using namespace std;

/*
    add code for struct here.
*/

struct Student {
    int age; 
    string first_name;
    string last_name; 
    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;
}
