🔹 Simple Calculator

A basic calculator that performs arithmetic operations:

#include <iostream>
using namespace std;

int main() {
    double num1, num2;
    char operation;
    
    cout << "Enter first number: ";
    cin >> num1;
    
    cout << "Enter operation (+, -, *, /): ";
    cin >> operation;
    
    cout << "Enter second number: ";
    cin >> num2;
    
    switch(operation) {
        case '+':
            cout << "Result: " << num1 + num2 << endl;
            break;
        case '-':
            cout << "Result: " << num1 - num2 << endl;
            break;
        case '*':
            cout << "Result: " << num1 * num2 << endl;
            break;
        case '/':
            if(num2 != 0)
                cout << "Result: " << num1 / num2 << endl;
            else
                cout << "Error: Division by zero!" << endl;
            break;
        default:
            cout << "Invalid operation!" << endl;
    }
    
    return 0;
}

Sample Output:

Enter first number: 10
Enter operation (+, -, *, /): +
Enter second number: 5
Result: 15

🔹 Number Guessing Game

A fun game where the computer picks a random number:

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main() {
    srand(time(0)); // Seed random number generator
    int secretNumber = rand() % 100 + 1; // Random number 1-100
    int guess;
    int attempts = 0;
    
    cout << "Welcome to the Number Guessing Game!" << endl;
    cout << "I'm thinking of a number between 1 and 100." << endl;
    
    do {
        cout << "Enter your guess: ";
        cin >> guess;
        attempts++;
        
        if (guess > secretNumber) {
            cout << "Too high! Try again." << endl;
        } else if (guess < secretNumber) {
            cout << "Too low! Try again." << endl;
        } else {
            cout << "Congratulations! You guessed it in " 
                 << attempts << " attempts!" << endl;
        }
    } while (guess != secretNumber);
    
    return 0;
}

🔹 Student Grade Manager

Store and calculate student grades:

#include <iostream>
#include <string>
using namespace std;

int main() {
    string studentName;
    int numSubjects;
    double totalMarks = 0;
    
    cout << "Enter student name: ";
    getline(cin, studentName);
    
    cout << "Enter number of subjects: ";
    cin >> numSubjects;
    
    for(int i = 1; i <= numSubjects; i++) {
        double marks;
        cout << "Enter marks for subject " << i << ": ";
        cin >> marks;
        totalMarks += marks;
    }
    
    double average = totalMarks / numSubjects;
    
    cout << "\n--- Student Report ---" << endl;
    cout << "Name: " << studentName << endl;
    cout << "Total Marks: " << totalMarks << endl;
    cout << "Average: " << average << endl;
    
    if(average >= 90) cout << "Grade: A+" << endl;
    else if(average >= 80) cout << "Grade: A" << endl;
    else if(average >= 70) cout << "Grade: B" << endl;
    else if(average >= 60) cout << "Grade: C" << endl;
    else cout << "Grade: F" << endl;
    
    return 0;
}
