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 the complete line till end,
and displays it as follows:

$./a.out
Enter a value : this is test

You entered: This is test

The scanf() and printf() Functions
The int scanf(const char *format, ...) function reads the input from the standard input
stream stdin and scans that input according to the format provided.
The int printf(const char *format, ...) function writes the output to the standard output
stream stdout and produces the output according to the format provided.
The format can be a simple constant string, but you can specify %s, %d, %c,
%f, etc., to print or read strings, integer, character, or float, respectively. There are many
other formatting options available which can be used based on requirements. Let us now proceed
with a simple example to understand the concepts better:

#include <stdio.h>

int main( )

{
char str[100];
int i;

printf( "Enter a value :");
scanf("%s %d", str, &i);

printf( "\nYou entered: %s %d ", str, i);

return 0;
