+# Control Flow Statements
+
+Control flow statements allow you to execute certain parts of your code if specific conditions are met. In C++, there are three main control flow statements: `if-else`, `switch`, and `goto`.
+
+## if-else
+The `if-else` statement is a fundamental control flow statement that allows you to execute one of two blocks of code depending on whether a condition is satisfied. This statement is useful for complex comparisons. 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 `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 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;
+
+ cout << "This line will be skipped";
+
+ line_3:
+ cout << "This is line 3";
+}
+```
