Continue in C language

What are the uses of Continue 

Continue statement is transfers execution control at the top of the loop where the condition checks. All statements after continue skips. The closing bracket of the loop does the same task. Continue statements should always be inside of a condition i.e. if, otherwise you may face infinite loop. Continue statement in C language I feel that the least useful feature.

Example : 

#include<stdio.h>

#include<conio.h>

Break Statement C Language

Break (Loop,Switch Case)

A break keyword is used to forcefully stop a loop. For example, you have set a loop to run 100 times and your requirement got fulfilled after 10 iterations then the loop will run 90 times which leads wastage of time and resource. So the break statement is used to stop the loop when need got complete.

Example: Write a program to input and sum ten numbers. Input will stop immediately when a user-entered number is dividing by 11 then the loop must be stopped.

#include<stdio.h>

#include<conio.h>

Single Link List

What is single link list

Link list is a dynamic data structure which occupies memory as required no memory wasted in contrast to Array. Data storage unit in list is called node as given below.

In link list node is created and dynamic space allocated while storing data. Next pointer point the next element of list you can add, delete data at any position of list. A start node points the first element of list.

One disadvantage of using arrays to store data is that arrays are static structures and therefore cannot be easily extended or reduced to fit the data set. Arrays are also expensive to maintain new insertions and deletions. In this chapter we consider another data structure called Linked Lists that addresses some of the limitations of arrays.
