+## If-Else Statement
+
+The `if-else` statement allows conditional execution based on boolean expressions.
+
+```cpp
+#include <iostream>
+
+int main() {
+ int num = 10;
+
+ // Check if the number is positive, negative, or zero
+ if (num > 0) {
+ std::cout << "Number is positive" << std::endl;
+ } else if (num < 0) {
+ std::cout << "Number is negative" << std::endl;
+ } else {
+ std::cout << "Number is zero" << std::endl;
+ }
+ return 0;
+}
+```
+
+### Explanation:
+- If `num` is greater than zero, it prints "Number is positive."
+- If `num` is less than zero, it prints "Number is negative."
+- Otherwise, it prints "Number is zero."
+
+---
+
+## Switch Statement
+
+The `switch` statement is used when multiple conditions depend on a single variable.
+
+```cpp
+#include <iostream>
+
+int main() {
+ int choice = 2;
+
+ // Evaluating different cases based on the value of 'choice'
+ switch (choice) {
+ case 1:
+ std::cout << "You chose option 1" << std::endl;
+ break; // Exit switch after executing this case
+ case 2:
+ std::cout << "You chose option 2" << std::endl;
+ break;
+ case 3:
+ std::cout << "You chose option 3" << std::endl;
+ break;
+ default:
+ std::cout << "Invalid choice" << std::endl;
+ }
+ return 0;
+}
+```
+
+### Explanation:
+- Depending on the value of `choice`, a corresponding message is printed.
+- The `break` statement ensures that the control exits after the matched case.
+- If no cases match, the `default` case executes.
+
+---
+
+## Goto Statement
+
+The `goto` statement allows jumping to a labeled statement within a function.
+
+```cpp
+#include <iostream>
+
+int main() {
+ int num = 5;
+
+ // If condition is met, jump to 'label'
+ if (num < 10)
+ goto label;
+
+ std::cout << "This will be skipped" << std::endl;
+
+ label:
+ std::cout << "Jumped to label" << std::endl;
+
+ return 0;
+}
+```
+
+### Explanation:
+- If `num` is less than 10, execution jumps to `label`.
+- The statement between `if` and `label:` is skipped.
