String function

In the previous post we learn about what is String.we know that string is a collection of two or more characters.In string we can store alphabet, digit and special symbols.

In this post we will learn what are the string functions.

String functions:

1.strcpy ( ):
This function is used to copy the source string into target string.
Syntax: strcpy(target string, source string);
Example:

void main()

{
char stirng1[10],string[20];

clrscr();

printf("type first stirng");

scanf("%s",string1);

strcpy(string2,string1);

printf("second string=%s",string2");

}

Output:
type first string: programming
second string: programming

2.strlen ( ):
This function is used to find out the length of the string.
Syntax: strlen(string name);

3.strcmp ( );
This function is used to compare two strings.if both values are equal then it will return zero.if first string is greater than second string it return value greater than zero.if the value is less than zero then it is case sensitive.
Syntax: strcmp(string1,string2);

4.strcat():
This function appends means add second string at the end of first string.

Syntax: strcat(string1,string2);

5.strrev():
This function reverse contents of the given string and store it again in the same variable.
Syntax: strrev(string);

Program to get 1 string input and print it.

String:

String is a collection of two or more characters.
In the previous post we learn about what is string.and How it can be print.

Program to get one string input and print it.

#include<stdio.h>
#include<conio.h>
void main()
{
char text[50];
clrscr();
printf("type string");
scanf("%s",&text);
printf("string is = %s",text);
getch();
}

Explanation:

1. Void main():

This is the first statement of every 'C' program,without main() function 'C' program cannot be start.If we didn't include main() function in 'C' program then error will be occurred.so every 'C' program must start with main() function.

2.char:
Char is a data type which is used for print the string.

3.Clrscr();

This is the clrscr() function.This function is used to clear the screen.This function is used to clear the output of the previous output window.

4.Printf():

Printf is a function which used to print any text or value on the screen.The text you want to print is enclosed in  double quote.you can see the below example:

                                   printf ("Hello world");

in the above example hello world will be printed.

5.getch();

This function is used to hold the output window.otherwise when you run your code it will display the output window just for a second so it is necessary to use it in our program.If we want to hold our  output screen.

What is String

String:

1. String is a collection of two or more characters.
2. In string we can store alphabets digits and special symbols.
3. when we declare array of character type then it is called as string.
4. In C, character type array is used to store a string.

Declaration of String:

The declaration of string is similar like Array.
for declaring string we need to specify its size means maximum of how many characters we have to store in string.

Syntax: char string[size];

Example: char str[20];

Here we declare a string variable str of size 20 means variable 'str' characters.

Initialization of String:

while declaring string we can also initialize some value at the time of declaration.

Syntax: char string[size]="text";

Example: char str[20]="programmingsolution";

Here we declare a string variable 'str' of size 20 and assign programmingsolution to it.

Inputting string:

To input the content in the string two function used as 'scanf()' and 'gets()'.
In 'scanf()' function spaces are not allowed in a string.if we give space then the remaining part will be truncated from string.
In 'gets()' function spaces are allowed in a string.

Syntax:    scanf("%s",string_variable);

                 gets(string_variable);

Example: scanf("%s",str);

                 gets(str);

what is WWW

In the previous post we learn about what is Web Browser and in this post we will learn What is WWW and What is the use of WWW.

WHAT IS WWW:

WWW is stand for world wide web.it is the universe of hypertext servers (HTTP servers) which are the servers that allow text, graphics, audio, video, sound file to be mixed together.The world wide web is a hypertext based system providing a uniform, user friendly interface for finding and accessing internet resources.

The world wide web is abbreviated as www or web is an information resource where documents and other web resources are identified by Uniform Resource Locators (URLs) that can be access by the internet.

WHAT IS THE USE OF WWW:

In 1980, a scientist developed programming language called as hypertext markup language (HTML). The program in which we write in this language is called as web page.Early web pages contain only textual information.but nowadays because of advanced technology web pages can contain audio, video, text, graphics, animation, sound and colors etc.by using the internet we can send the information receive the information or share the information from different computers of different networks from any place.

The WWW is  a series of documents called as web pages developed using HTML and which can be accessed  by using the internet with the help of web browser.We can say that the WWW is a market place.WWW is also called as W3.The WWW and HTTP allow to call the link from one page to another page that page may contain  audio, video etc and textual information.

2d array in C

In the previous post we learn about what is array and what is one dimensional array.In this post we will learn what is two dimensional array.

What is Array:

• Array is a collection of similar type of data type.
• Array is used to store more than one values of same data type under a single variable name in a continuous memory location.

What is two dimensional Array:

1. Two dimensional array consist of number of rows and number of columns.
2. Each row consist of specified number of columns.
3. For accessing element in two dimensional array we have to provide array name followed by row number and column number.
4. If we skip the column number then specified row number and first column that is zero index value is accessed.
5. If we skip both column and row then first row (index zero) and first column (index zero) value is accessed.

How to declare two dimensional Array:              

1. To declaring two dimensional array we have to write data type followed by followed by array name followed by total number of rows and followed by total number of columns in each row.
2. Row and column numbers are specified in separate square brackets ([ ]).

Syntax: Data type Array name [row][column];

Example:int num[5][5];

How to initialize two dimensional Array:

1. We can assign the values to array elements at the time of declaration of array.
2. Each rows values are enclosed within separate inner parenthesis and two values are separated by comma (,).

Syntax: data type arrayname [row][column]={0th row elements}

                                                                         {1st row elements}
                                                                          .....
                                                                          };
Example: int num [5][5]={{1,2,3,4,5},{2,4,6,7,8},{5,6,7,8,9,}};
