 The `for` loop executes a block of code until a specified condition is false. Use `while` loops when the number of iterations are variable, otherwise use `for` loops. A common use of `for` loops are array iterations. 
 It is also known as an 'entry-controlled loop' since the condition is checked before the next iteration. Another example of an 'entry-controlled loop' is a while loop. 
+The block of code around which the <b>for</b> loop iterates is packed inside the curly braces. A <b>for</b> loop is also acceptable without curly braces. The compiler assumes only the 1st statement to be under the <b>imaginary curly braces</b>.
+A variable declared inside the curly braces of a <b>for</b> loop is only valid inside that particular for loop. We cannot use a variable declared inside a <b>for</b> loop outside it.
