A function is a collection of statements grouped together to do some specific task. It may return a value. However, in no case a function will return more than one value. What does it mean by returning a value and where it is returned? To understand this let us consider an example.
Function arguments are the inputs passed to a function. A function must declare variables to accept passed arguments. A variable that accepts function argument is known as function parameter.
In programming function argument is commonly referred as actual parameter and function parameter is referred as formal parameter. I will be using these words interchangeably throughout this series of C programming tutorial.
A function is a collection of statements grouped together to do some specific task. In series of learning C programming, we already used many functions unknowingly. Functions such as -
pow() or the most important the main() function. Every C program has at least one function i.e. the
Infinite loop is a looping construct that iterates forever. In programming life either intentionally or unintentionally, you come across an infinite loop. Generally a program in an infinite loop either produces continuous output or does nothing. Infinite loops are also known as indefinite or endless loop.
As a novice programmer, you must know how to debug an infinite loop. As an intermediate programmer you must know how and when to use infinite loop. Let us first learn when to use infinite loop and how to define.
goto is a jump statement used to transfer program control unconditionally from one part of a function to another. I have used the word unconditionally because there is no restriction on control transfer. You can transfer program control from one position to any position within a function. Many programmers uses
goto to gain full control on their program.
In the series of learning C programming, we learned to repeat a set of statements and terminate a repetitive statement using
break. Here in this post, I will explain another program flow control statement i.e.
In this post I will explain the use and importance of
break statement in program flow control.
do...while is an exit controlled looping statement. We use
do...while loop when there is a need to check condition after execution of loop body.
do...while loop in any case executes minimum once.
