+# Branching Statements
+
+Branching statements allow you to conditionally or unconditionally execute different parts of your code. The branching statements that will be covered are `if-else`, `switch`, and `goto`.
+
+## if-else
+The `if-else` statement is a conditional branching statement that allows you to execute one of two blocks of code depending on whether a condition is satisfied. This statement is useful for making decisions based on a boolean expression. The syntax for the `if-else` statement is:
+
+```cpp
+if (condition) {
+    // Block of code executed if the condition is true
+} else {
+    // Block of code executed if the condition is false
+}
+```
+
+For example:
+
+```cpp
+#include <iostream>
+using namespace std;
+
+int main() {
+    int a = 10, b = 5;
+    if (a > b) {
+        cout << "a is greater than b";
+    } else {
+        cout << "b is greater than a";
+    }
+}
+```
+
+## switch
+The `switch` statement allows you to execute different blocks of code based on the value of a `control variable`. It uses `cases` to define code blocks that run when a specific value matches. A `default` case is executed if none of the other cases match. Each `case` must end with a `break` statement; otherwise, all following cases will execute. `switch` is useful when you want to compare a `control variable` to multiple constant values. The syntax for the `switch` statement is:
+
+```cpp
+switch (control_variable) {
+    case 1: {
+        // Code to be executed for case 1
+        break;
+    }
+    case 2: {
+        // Code to be executed for case 2
+        break;
+    }
+    default: {
+        // Code to be executed if no cases match
+        break;
+    }
+}
+```
+
+For example:
+
+```cpp
+#include <iostream>
+using namespace std;
+
+int main() {
+    int ch;
+    cout << "Select a language: 1. English 2. French";
+    cin >> ch;
+    switch (ch) {
+        case 1: {
+            cout << "Good morning!";
+            break;
+        }
+        case 2: {
+            cout << "Bonjour!";
+            break;
+        }
+        default: {
+            cout << "The option does not exist :)";
+            break;
+        }
+    }
+}
+```
+
+## goto
+The `goto` statement allows you to unconditionally jump to different parts of your program using `labels` as location points. The syntax for `goto` is:
+
+```cpp
+goto label_name;
+```
+
+For example:
+
+```cpp
+#include <iostream>
+using namespace std;
+
+int main() {
+    cout << "This is line 1";
+    goto line_3;
+
+    // This line will be skipped
+    cout << "This line will be skipped";
+
+line_3:
+    cout << "This is line 3";
+}
+```
