# Write a program to find the factorial of a number using for loop

Various ways to iterate over sequences The sequence functions illustrated in 4. We can randomize the contents of a list s before iterating over them, using random. We can convert between these sequence types. Even ignoring minor differences in syntax there are many differences in how these statements work and the level of expressiveness they support. Generally, for-loops fall into one of the following categories: Some languages require a separate declaration of the control variable, some do not.

Another form was popularized by the C programming language. It requires 3 parts: The type of a variable should be same if you are using multiple variables in initialization part. The condition checks a condition, and quits the loop if false.

The afterthought is performed exactly once every time the loop ends and then repeats. Here is an example of the traditional for-loop in Java. Foreach loop This type of for-loop is a generalisation of the numeric range type of for-loop, as it allows for the enumeration of sets of items other than number sequences.

It is usually characterized by the use of an implicit or explicit iteratorin which the loop variable takes on each of the values in a sequence or other data collection. A representative example in Python is: Some languages have this in addition to another for-loop syntax; notably, PHP has this type of loop under the name for each, as well as a three-expression for-loop see below under the name for. Vectorised for-loops[ edit ] Some languages offer a for-loop that acts as if processing all iterations in parallelsuch as the for all keyword in FORTRAN 95 which has the interpretation that all right-hand-side expressions are evaluated before any assignments are made, as distinct from the explicit iteration form.

In the for all version, however, each calculation refers only to the original, unaltered A.

Thus pseudocode such as A: The example loop could be rendered as A 2: That is, a value is assigned to the loop variable i and only if the while expression is true will the loop body be executed. If the result were false the for-loop's execution stops short.

Loop counters[ edit ] In computer programming a loop counter is the variable that controls the iterations of a loop a computer programming language construct. It is so named because most uses of this construct result in the variable taking on a range of integer values in some orderly sequences example.

The loop counter is used to decide when the loop should terminate and for the program flow to continue to the next instruction after the loop. A common identifier naming convention is for the loop counter to use the variable names i, j, and k and so on if neededwhere i would be the most outer loop, j the next inner loop, etc.

The reverse order is also used by some programmers. This style is generally agreed to have originated from the early programming of FORTRAN [ citation needed ], where these variable names beginning with these letters were implicitly declared as having an integer type, and so were obvious choices for loop counters that were only temporarily required.

The practice dates back further to mathematical notation where indices for sums and multiplications are often i, j, etc. A variant convention is the use of reduplicated letters for the index, ii, jj, and kk, as this allows easier searching and search-replacing than using a single letter.Table of Content.

Identifiers are sequences of characters used for naming variables, functions, new data types, and preprocessor macros. You can include letters, decimal digits, and the underscore character ‘_’ in identifiers. The first character of an identifier cannot be a digit. Introduction ¶. This document serves as a high level summary of the optimization features that LLVM provides.

Optimizations are implemented as Passes that traverse some portion of a program to either collect information or transform the program. C Program to print all even numbers up to inputted number
