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.

Actual and former parameter C Language

As we know C language is building block of function. Anything done in C language by function. Function can take argument. There are two types of argument given below.

• Argument pass while calling is actual
• Argument while declaring function is former

#include<stdio.h>

#include<conio.h>

     Formal and actual parameter program

  ##########################*/

int sum(int,int);

void main()

{

     int a,b,c;

     clrscr();

     a=10;

     b=20;

     c=sum(a,b);   /* a and b are actual parameter */

     printf("\n\tA=%d\n\tB=%d\n\tSum=%d",a,b,c);

     getch();

}

int sum(n1,n2) /* n1,n2 are formal parameter */

{

     return n1+n2;

}

In the function main in the example above, a, and b are all actual parameters when used to call calculate sum function. On the other hand, the corresponding variables in sum_funcation definition (namely n1, n2) are all formal parameters because they appear in a function definition.

Difference between function definition and function declaration

Difference between  function definition and function declaration

DECLARATION	DEFINITION
A variable or a function can be declared any number of times	A variable or a function can be defined only once
Memory will not be allocated during declaration	Memory will be allocated
int f(int); The above is a function declaration. This declaration is just for informing the compiler that a function named f with return type and argument as int will be used in the function.	int f(int a) {   return a; } The system allocates memory by seeing the above function definition.
