Strings

A string is a group of characters, usually letters of the alphabet, In order to format your print display in such a way that it looks nice, has meaningful names and titles, and is aesthetically pleasing to you and the people using the output of your program.

In fact, you have already been using strings in the examples of the previous topics. But it is not the complete introduction of strings. There are many possible cases in the programming, where the use of formatted strings helps the programmer to avoid the too many complications in the program and too many bugs of course.

A complete definition of a string is a series of character type data terminated by a null character (‘\0’).

When C is going to use a string of data in some way, either to compare it with another string, output it, copy it to another string, or whatever, the functions are set up to do what they are called to do until a null is detected.

There is no basic data type for a string in C Instead; strings in C are implemented as an array of characters. For example, to store a name you could declare a character array big enough to store the name, and then use the appropriate library functions to manipulate the name.

The following example displays the string on the screen, entered by user:

#include <stdio.h>
int main()
{
char name[80]; /* Create a character array
called name */

printf("Enter your name: ");
gets(name);

printf("The name you entered was %s\n", name);
return 0;
}

The execution of the program will be:

Enter your name: Tarun Tyagi
The name you entered was Tarun Tyagi
