Examples and Practice Exercises in Cpp

A. Implementing decision-making logic in C++ programs

Determine if a number entered by the user is positive, negative, or zero:

#include <iostream>
int main() {
    int number;
    std::cout << "Enter a number: ";
    std::cin >> number;
    if (number > 0) {
        std::cout << "The number is positive.";
    }else if (number < 0) {
        std::cout << "The number is negative.";
    } else {
        std::cout << "The number is zero.";
    }
    return 0;
}

Check if a given year is a leap year or not:

#include <iostream>
int main() {
    int year;
    std::cout << "Enter a year: ";
    std::cin >> year;
    if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
         std::cout << "Leap year!";
    } else {
        std::cout << "Not a leap year.";
    }
    return 0;
}

B. Solving problems using conditional statements and operators

Find the maximum of three numbers using if-else statements:

#include <iostream>
int main() {
    int a, b, c;
    std::cout << "Enter three numbers: ";
    std::cin>> a >> b >> c;
    int max = a;
    if (b > max) {
        max = b;
    }
    if (c > max) {
        max = c;
    }
    std::cout << "The maximum number is: " << max;
    return 0;
}

Check if a given character is a vowel or a consonant using switch statements:

#include <iostream>
int main() {
    char ch;
    std::cout << "Enter a character: ";
    std::cin>> ch;
    switch (tolower(ch)) {
        case 'a':
        case 'e':
        case 'i':
        case 'o':
        case 'u':
            std::cout << "Vowel";
            break;
        default:
            std::cout << "Consonant";
    }
    return 0;
}

These code snippets provide examples and practice exercises for implementing decision-making logic in C++. Use them to practice and reinforce your understanding of conditional statements, comparison, and logical operators. Experiment with different inputs and scenarios to enhance your problem-solving skills using these concepts.

Throughout this guide, we have covered various aspects of decision-making in C++. We explored conditional statements, comparison, logical, and ternary operators. We also discussed best practices and provided examples and practice exercises to reinforce your understanding.

Decision-making is a fundamental aspect of programming. It allows you to control the flow of your code and make your programs dynamic and responsive. Mastering decision-making skills in C++ enables you to write efficient, robust, and flexible code that can handle different scenarios and make intelligent choices based on conditions.

Decision-making skills are honed through practice and exploration. As you continue your programming journey, we encourage you to challenge yourself with more complex decision-making scenarios. Explore advanced techniques like nested conditional statements, compound conditions, and decision trees. This will expand your problem-solving abilities and enhance your overall programming skills.

Remember, decision-making is not only about understanding syntax and constructs; it's about logical thinking, problem-solving, and making informed choices. Embrace the power of decision-making in C++ and continue to sharpen your skills through practice and continuous learning.

Happy coding!
