cout << “Enter first number: “; cin >> num1;
cout << “Enter operator (+, -, *, /): “; cin >> op;
cout << “Enter second number: “; cin >> num2;
switch(op) {
case ‘+’: cout << num1 + num2; break;
case ‘-‘: cout << num1 – num2; break;
case ‘*’: cout << num1 * num2; break;
case ‘/’:
if(num2 != 0) cout << num1 / num2;
else cout << “Cannot divide by zero!”;
break;
default: cout << “Invalid operator!”;
}
return 0;
}
Step-by-Step Guide

Number Guessing Game
Overview
A fun game project for beginners to learn loops, conditionals, and random number generation.
Features
Generate a random number
Take user guesses
Provide hints (higher/lower)
Sample Code
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main() {
srand(time(0));
int number = rand() % 100 + 1;
int guess;
cout << “Guess a number between 1 and 100: “;
do {
cin >> guess;
if(guess > number) cout << “Lower! Try again: “;
else if(guess < number) cout << “Higher! Try again: “;
else cout << “Correct! You guessed the number.”;
} while(guess != number);
return 0;
}
Step-by-Step Guide
Use rand() and srand(time(0)) for random number generation
Implement a do-while loop to keep taking guesses
Give hints for higher or lower guesses
Optional: Add a score counter for attempts
Pro Tip: Include a README.md explaining the game rules for GitHub.
Tic-Tac-Toe Game
Overview
Tic-Tac-Toe teaches arrays, loops, and functions. Beginners learn how to structure a multi-function C++ program.
Features
Player vs Player mode
Display board in the console
Check for win conditions
Sample Code
#include <iostream>
using namespace std;
char board[3][3] = {{‘1′,’2′,’3’},{‘4′,’5′,’6’},{‘7′,’8′,’9’}};
void displayBoard() {
for(int i=0;i<3;i++) {
for(int j=0;j<3;j++) cout << board[i][j] << ” “;
cout << endl;
}
}
Step-by-Step Guide
Initialize a 3×3 board
Create functions for displaying board, checking win, and updating moves
Implement a loop for alternating turns
