Write a for loop in c

C Tutorial — for loop, while loop, break and continue In every programming language, thus also in the C programming language, there are circumstances were you want to do the same thing many times.

Write a for loop in c

By Alex Allain Loops are used to repeat a block of code. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming -- many programs or websites that produce extremely complex output such as a message board are really only executing a single task many times.

They may be executing a small number of tasks, but in principle, to produce a list of messages only requires repeating the operation of reading in some data and displaying it. Now, think about what this means: There are three types of loops: Each of them has their specific uses. They are all outlined below.

FOR - for loops are the most useful type. Second, the condition tells the program that while the conditional expression is true the loop should continue to repeat itself. The variable update section is the easiest way for a for loop to handle changing of the variable.

Notice that a semicolon separates each of these sections, that is important.

Also note that every single one of the sections may be empty, though the semicolons still have to be there. If the condition is empty, it is evaluated as true and the loop will repeat until something else stops it. Keep in mind also that the variable is incremented after the code in the loop is run for the first time.

It can be any combination of boolean statements that are legal. Notice that a while loop is the same as a for loop without the initialization and update sections.

However, an empty condition is not legal for a while loop as it is with a for loop. The easiest way to think of the loop is that when it reaches the brace at the end it jumps back up to the beginning of the loop, which checks the condition again and decides whether to repeat the block another time, or stop and move to the next statement after the block.

WHILE loops are useful for things that want to loop at least once. If the condition is true, we jump back to the beginning of the block and execute it again. A while loop says "Loop while the condition is true, and execute this block of code", a do. A common error is to forget that a do. Notice that this loop will execute once, because it automatically executes before checking the condition.Loops are used in programming to repeat a specific block of code.

In this article, you will learn to create while and do while loops in C++ programming. One of the most common tasks in CUDA programming is to parallelize a loop using a kernel.

As an example, let’s use our old friend SAXPY.

Your Answer

Here’s the basic sequential implementation, which uses a for loop. To efficiently parallelize this, we need to launch enough threads to fully utilize the GPU. void saxpy(int n, float a, [ ].

The syntax of a for loop in C programming language is − for (init; condition; increment) { statement(s); } Here is the flow of control in a 'for' loop − The init step is executed first, and only once.
