When the above code is compiled and executed, it waits for you to input some text. When
you enter a text and press enter, then the program proceeds and reads only a single character and
displays it as follows:

$./a.out

Enter a value : this is test
You entered: t

The gets() and puts() Functions
The char *gets(char *s) function reads a line from stdin into the buffer pointed to by s
until either a terminating newline or EOF (End of File).
The int puts(const char *s) function writes the string ‘s’ and ‘a’ trailing newline to
stdout.

#include <stdio.h>
int main( )

{
char str[100];

printf( "Enter a value :");

gets( str );

printf( "\nYou entered: ");
