![]() But I would almost argue this is a lucky happenstance, not by good program design. What happens if n is 1 or 2? Will this loop return anything, or will it generate a garbage result? In fact, the loop will generate the correct result of 1, which is what F(1) and F(2) are for the Fibonacci sequence. ![]() An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Put one final line of code after the loop terminates, a = a(end) There is no need even for a test on the value of i. if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An explicit loop counter distinguishes the ‘for loop’ from other looping statements. The code block is implemented as long as those defined conditions are met. It checks for desired conditions and then executes a block of code repeatedly. Given an integer n, calculate the sum of the integers k 2 for k 1.,n. For loop is a conditional iterative statement used in programming languages. Code here to be executed for each value of variable.
