What is String in C?
String is a collection of characters. It is a one dimensional array of characters.
There are two ways to declare string in c language.
1. By char array
2. By string literal
Declaring string by char array
char c[11]={'i', 'n', 't', 'e', 'l', 'l', 'i', 'p', 'a', 'a', 't' ,’\0'};
Declaring string by string literal
char c[]="intellipaat";
Example
#include <stdio.h>
#include <conio.h>
void main ()
{
char c1[11]={'i', 'n', 't', 'e', 'l', 'l', 'i', 'p', 'a', 'a', 't' ,’\0'};
char c2[]="intellipaat";
printf("Char Array Value : %s\n", c1);
printf("String Literal Value : %s\n", c2);
getch();
}
