String Handling in C Programming Language

String Handling in C Programming Language

In this tutorial, we will explain String handling and their operations ic C language. We have to handle String in C language using character array because there is no special data type for String in C language. The array of characters or set of characters can be called String in C.

char is one of the variable types in C language that contains a single character. But, the set of character is also known as an array of character represents a string in C language.

The array of characters are terminated by a null of character “n”;

Memory presentation of string in C using char array

char greeting[]=”Hello”;  //Declaration and initialization char in C

String manipulation

• Name of the person
• Address of the house
• Name of items

Declaration of String

Declare of a String in C Language two ways

1. Using an Array
2. Using a Pointer

Using an Array

    Diclaration                                                                                                                                       

Syntex

char c[];

or

char c[25];

Initialization of String                                                                                                                      

char c[]=”kanthan”;

or

char c[20]=”kanthan”;

or

char c[]={‘k’,’a’,’n’,’t’,’h’,’a’,’n’}

or

char c[7]={‘k’,’a’,’n’,’t’,’h’,’a’,’n’}

Using Pointer

    Declaration and Initialization of String

Syntex

char *c=””kanthan;;

When the above code is executed, it produces the following result

His name is kanthan

Example 2

When the above code executed, produced following result

Enter youe name...
Devid peris
