Program:

#include <stdio.h> 
int main() 
{ 
    char a[] = "atnyla"; 
    printf("%s\n", a); 
    return 0; 
}

Output:

atnyla

Explanation:

The %s format specifier is implemented for representing strings. This is used in printf() function for printing a string stored in the character array variable. When you have to print a string, you should implement the %s format specifier.

Syntax:
printf("%s",<variable name>);

The given code is a C program that declares a character array a and initializes it with the string "atnyla". The printf() function is then used with the %s format specifier to print the contents of the a array to the console.

Here's how it works:

  • The #include <stdio.h> line includes the standard input/output library in the program.
  • The main() function is the entry point of the program.
  • The character array a is declared and initialized with the string "atnyla".
  • The printf() function is used to display the contents of a using the %s format specifier.
    • %s is a format specifier used to display a string of characters.
  • The \n character is used to insert a newline after the output is printed.
  • Finally, the return 0; statement terminates the program and returns 0 to the operating system indicating that the program executed successfully.
