May 13, 2025 · A function in C is a set of statements that, when called, perform some specific tasks. It is the basic building block of a C program that provides modularity and code reusability. They are also called subroutines or procedures in other languages. Function Definition

A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.

In programming, a loop is used to repeat a block of code until the specified condition is met. C programming has three types of loops: We will learn about for loop in this tutorial. In the next tutorial, we will learn about while and do...while loop. The syntax of the for loop is: // statements inside the body of loop . How for loop works?

Every C program has at least one function, which is main (), and all the most trivial programs can define additional functions. When the algorithm of a certain problem involves long and complex logic, it is broken into smaller, independent and reusable blocks.

Nov 3, 2021 · In this section, you'll learn the basic syntax of for loops in C. The general syntax to use the for loop is shown below: for (initialize; check_condition; update) { //do this }

Jun 29, 2020 · In this tutorial, we will learn functions in C programming. A function is a block of statements that performs a specific task. Let’s say you are writing a C program and you need to perform a same task in that program more than once. In such case you have two options:

Sep 11, 2017 · Functions such as – printf(), scanf(), sqrt(), pow() or the most important the main () function. Every C program has at least one function i.e. the main() function. Why use functions? A program is a collection of small tasks that may depend on other tasks. You can use two approaches to write a program.

The C style for loop consists of three expressions: for (initializer; condition; counter) statement_or_statement_block; The initializer runs once, when the loop starts.

Jan 9, 2019 · The For Loop is a loop where the program tells the compiler to run a specific code FOR a specified number of times. This loop allows using three statements, first is the counter initialization, next is the condition to check it and then there is an increment/decrement operation to change the counter variable.

May 20, 2025 · In C programming, the for loop is used to repeatedly execute a block of code as many times as instructed. It uses a variable (loop variable) whose value is used to decide the number of repetitions. It is generally used when we know how many times we want to repeat the code. Let's take a look at an example:
