Problem Statement

Write a C++ program implementing a console-based student management system supporting record addition, searching by roll number, updating marks, and listing all students using OOP and STL vectors.

Input Format

Number of operations N, followed by operation commands ('ADD', 'SEARCH', 'UPDATE') with respective student parameters.

Output Format

Print execution results or student records.

Constraints

1 <= N <= 50

Sample Input

3

SEARCH 101
UPDATE 101 95.0

Roll: 101, Name: John, Marks: 88.50
Updated

Explanation

Integrates classes, encapsulation, vector storage, and search queries for a complete CRUD mini application.

    Student(int r, std::string n, float m) : roll(r), name(n), marks(m) {}
};

int main() {
    int n;
    if (std::cin >> n) {
