-# Control Flow & Statements
+# Control Flow & Statements
+Control flow & statements provides the ability to make decision which part of code should be executed or not based on certain conditions(also called decision control statements). In C++, the different types of control statements are:
+
+Basic:
+  1. if statement
+  2. if else statement
+  3. if else if statement
+  4. nested if statement
+  5. switch statement
+
+Advanced:
+
+  6. ternary operator
+  7. Jump statement
+
+  ## Example if statement
+  Simplest way to check weather a conditon is true or false and make a decision.
+
+```cpp
+  //Syntax
+
+  if(condition_to_be_evaluated){
+  //code to be executed when condition evaluates to true.
+  // this section will only execute if specified condition is
+  // met. Else it won't.
+  }
+
+```
+  ```cpp
+     int age = 19;
+     // check if age is greater than 19.
+     if(age > 18) {
+      std::cout << "You are eligible to vote" << std::endl;
+     }
+```
+Note: You can skip to write curly brasses if there is only one statement.
+```cpp
+    int age = 19;
+    if (age > 18)
+        cout << "allowed to vote";
+    return 0;
+```
