In C programming, a for loop is used to repeat a block of statements until a specified condition is satisfied. And It is also known as an entry-controlled loop.

How many times does the for loop execute in C?
In this case, the loop is executed 10 times. Once for each of the values 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 for the variable c, and in that order. The loop variable c is initialized with 0 (“c = 0”), the condition is checked (“c < 10”), the loop itself is executed (the part with the comment), the loop variable is increme. Continue Reading.
What is the full "for" loop syntax in C?
Syntax
- The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. ...
- Next, the condition is evaluated. If it is true, the body of the loop is executed. ...
- After the body of the 'for' loop executes, the flow of control jumps back up to the increment statement. ...
- The condition is now evaluated again. ...
Which loop is more efficient in C?
which loop i more efficient depends on which purpose the loop is used. if you want to set a loop counter to an initial value,test the loop counter to determine whether its value has reaches the number of repetitions desired and increase the value of the loop counter in a single line you can use for loop which is probably the most popular looping instruction.
What is the most basic loop in C?
Loops are among the most basic and powerful of programming concepts. A loop in a computer program is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question. If the answer requires action, it is executed. The same question is asked again and again until no further action is required.
What is a for loop in C?
The for loop in C language is used to iterate the statements or a part of the program several times. It is frequently used to traverse the data structures like the array and linked list.
What is for loop in C example?
Example 2: for loop Suppose, the user entered 10. The count is initialized to 1 and the test expression is evaluated. Since the test expression count<=num (1 less than or equal to 10) is true, the body of for loop is executed and the value of sum will equal to 1.
What are the 3 types of loops in C?
In C programming, there are three types of loops, namely For Loop, While Loop and Do While Loop. Loops in C can also be combined with other control statements that include Break statement, Goto statement and Control statement.
What is the syntax of for loop?
Example explained Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end.
How do you write a for loop?

And thenMoreSo let's start off and say if you want to print something 12 times so we'll do n equals 12. And then we want to do something 12 times we need a four loop.
How does a for loop start?
The For Loop Statement 1 is executed (one time) before the execution of the code block. Statement 2 defines the condition for executing the code block. Statement 3 is executed (every time) after the code block has been executed.
Which loop is faster in C language?
"Do-While loop is the fastest loop in C programming".
Who is the father of C language?
Dennis RitchieC / Designed byDennis MacAlistair Ritchie was an American computer scientist. He is most well-known for creating the C programming language and, with long-time colleague Ken Thompson, the Unix operating system and B programming language. Wikipedia
What type of loop is a for loop?
A for loop is a control flow statement for specifying iteration, which allows code to be executed repeatedly. A for loop has two parts: a header specifying the iteration, and a body which is executed once per iteration.
What is for statement in C?
The for statement lets you repeat a statement or compound statement a specified number of times. The body of a for statement is executed zero or more times until an optional condition becomes false.
What are the 3 parts of a for loop?
Similar to a While loop, a For loop consists of three parts: the keyword For that starts the loop, the condition being tested, and the EndFor keyword that terminates the loop.
How can I learn C language?
Get started with C. Official C documentation - Might be hard to follow and understand for beginners. Visit official C Programming documentation. Write a lot of C programming code - The only way you can learn programming is by writing a lot of code.
Description
A "For" Loop is used to repeat a specific block of code (statements) a known number of times. The for-loop statement is a very specialized while loop, which increases the readability of a program. Here is the syntax of the of for loop.
For loop Examples
The following program calculate the sum of 1+2+3+...+50. The sum is stated in sum = sum + x, where i takes values from 1 to 50.
C Programming: Tips of the Day
Because of Short-circuit evaluation, when x is 0, y and z don't really need to be evaluated since 0 && ANYTHING is 0.
What is a loop in programming?
In computer programming, loops are used to repeat a block of code. For example, let's say we want to show a message 100 times. Then instead of writing the print statement 100 times, we can use a loop.
What happens if a for loop is always true?
If the condition in a for loop is always true, it runs forever (until memory is full). For example, In the above program, the condition is always true which will then run the code for infinite times. In the next tutorial, we will learn about while and do...while loop.
Syntax
The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears.
Example
When the above code is compiled and executed, it produces the following result −
Description
Why For Loops?
- 1. " For" loops execute blocks of code over and over again. 2. It is clear to a developer exactly how many times the loop will execute before the loop starts. 3. The Syntax of the for loop is almost same to other programming languages.
For Loop Repetition Statement
- Here are some example of for loop repetition statements. The following code prints the numbers from 1 to 100 in increments of 1. The following code prints the numbers from 100 to 1 in increments of -1. The following code prints the numbers from 8 to 88 in steps of 8 The following code prints : 2, 7, 12, 17, 22, 27 The following code prints: 66, 60, 54, 48, 42, 36, 30, 24, 18, 12, 6, 0
For Loop Examples
- Example - 1: The following program calculate the sum of 1+2+3+...+50. The sum is stated in sum = sum + x, where i takes values from 1 to 50. Output: Example - 2: The following program will ask the user to input 10 integers and find the sum. Output: Example - 3: The following program will ask the user to input 5 numbers and print out the maximum and minimum numbers from the set. Ou…
