#include <iostream>

struct student
{
    std::string name;
    int age;
    float mark;
} s[3];

int main()
{
    for (int i = 0; i < 3; i++) {
        s[i].name = "abc-" + std::to_string(i);;
        s[i].age = (i + 1) * 16;
        s[i].mark = (i + 1) * 27;
    }

    for (int i = 0; i < 3; i++) {
        std::cout << "Name: " << s[i].name << ' ';
        std::cout << "Age: " << s[i].age << ' ';
        std::cout << "Mark: " << s[i].mark << '\n';
    }

    return 0;
}



/*
run:

Name: abc-0 Age: 16 Mark: 27
Name: abc-1 Age: 32 Mark: 54
Name: abc-2 Age: 48 Mark: 81
