C Strings

You will need to use character strings in most of your program - names, address, state, district and so on. Thus understanding about strings in C programming is necessary. The following four points are good enough to make use of strings

  • In C, strings are arrays of characters.
  • Every string in a c program is ends with '\0' character.
  • Strings are always enclosed within double quotes.
  • If the program uses the string functions, it must define the header file string.h.

Syntax - Strings

char str[12] = "ThisisString";

Program - Strings

#include <stdio.h>
int main()
char nation[20] = "2Braces India";
printf("%s", nation);
return 0;
  • 2Braces India


The program prints the string stored in a variable 'nation'. The above program don't require the header file "string.h", because there is no string functions.

What Is String Literals

We have already made extensive use of string literals for output. Just about every time the printf() method or function was used in the above example too, we used a string literal as the argument. A string literal is nothing more than a sequence of characters between double quotes.
"This is a string literal"
