Knowledge and skills required to master C technology

Basic knowledge

• C syntax and semantics
• Data types, variables and operators
• Control flow (if, for, while)
• Functions and classes

Object-oriented programming (OOP) concepts

• Encapsulation, inheritance and polymorphism
• Classes, objects and member functions
• Virtual functions and abstract classes

Data structures and algorithms

• Arrays, linked lists, stacks and queues
• Sort and Search algorithms (for example: merge sort, quick sort)
• Memory management and pointers

C Features

• Template (generic type programming)
• Exception handling
• Input/output stream (iostream)
• Memory management (new/delete)

Practical combat Case

Student Performance Management System

This is a simple C program used to manage student performance data:

#include <iostream>
#include <vector>

using namespace std;

class Student {
public:
    string name;
    vector<int> grades;
};

int main() {
    // 创建学生对象列表
    vector<Student> students;

    // 添加学生数据
    Student s1 = {"John", {90, 85, 88}};
    Student s2 = {"Mary", {85, 92, 89}};
    students.push_back(s1);
    students.push_back(s2);

    // 计算学生平均成绩
    for (auto& student : students) {
        double sum = 0;
        for (auto& grade : student.grades) {
            sum += grade;
        }
        cout << student.name << ": " << sum / student.grades.size() << endl;
    }

    return 0;
}

This The program demonstrates basic concepts of object-oriented programming, data structures, and algorithms in C.
