Introduction
These statements act as navigators, allowing your code to make decisions based on specific conditions. In this exploration, we’ll delve into the intricacies of conditional statements, empowering you to shape the dynamic flow of your programs.
If Statements
The if statement is a fundamental building block:
#include <iostream>
int main() {
int number = 10;
if (number > 0) {
std::cout << "The number is positive." << std::endl;
}
return 0;
}
If-Else Statements
Extend your control with else to handle alternative conditions:
#include <iostream>
int main() {
int number = -5;
if (number > 0) {
std::cout << "The number is positive." << std::endl;
} else {
std::cout << "The number is non-positive." << std::endl;
}
return 0;
}
If-Else-If Statements
Handle multiple conditions using else if:
#include <iostream>
int main() {
int number = 0;
if (number > 0) {
std::cout << "The number is positive." << std::endl;
} else if (number < 0) {
std::cout << "The number is negative." << std::endl;
} else {
std::cout << "The number is zero." << std::endl;
}
return 0;
}
Switch Statements
Switch statements offer an elegant way to handle multiple conditions:
#include <iostream>
int main() {
char grade = 'B';
switch (grade) {
case 'A':
std::cout << "Excellent!" << std::endl;
break;
case 'B':
std::cout << "Good job!" << std::endl;
break;
case 'C':
std::cout << "You passed." << std::endl;
break;
default:
std::cout << "Invalid grade." << std::endl;
}
return 0;
}
Exercise: Implement Different Conditional Logics
Now, let’s practice what we’ve learned. Implement different conditional logics in C++.
Conclusion
Feel free to modify the conditions and values to create various scenarios and practice different aspects of conditional statements in
C++. Mastering conditional statements opens the door to dynamic and responsive programming, enhancing your ability to create sophisticated and efficient code structures. Happy coding!
