## Objective :

From Playing With Characters HackerRank Solution , This challenge will help you to learn how to take a character, a string and a sentence as input in C. To take a single character ch as input, you can use scanf(“%c”, &ch ); and printf(“%c”, ch) writes a character specified by the argument char to stdout

char ch;

scanf(“%c”, &ch);

printf(“%c”, ch);

This piece of code prints the character ch . You can take a string as input in C using scanf(ā%sā, s). But, it accepts string only until it finds the first space.

In order to take a line as input, you can use scanf(“%[^\n]%*c”, s); where s is defined as char s[MAX_LEN] where MAX_LEN is the maximum size of s . Here, [] is the scanset character. ^\n stands for taking input until a newline isn’t encountered. Then, with this %*c, it reads the newline character and here, the used * indicates that this newline character is discarded.

## Task:

You have to print the character, ch , in the first line. Then print in next line. In the last line print the sentence, sen.

The required Format of output is:

Print three lines of output. The first line prints the character, ch.
The second line prints the string, s .
The third line prints the sentence, sen .

## Input Format:

First, take a character, ch Ā as input.
Then take the string, sĀ as input.
Lastly, take the sentence senĀ as input.

## Solution Solution :

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

#define MAX_LEN 128

int main()
{
char ch;
char word[MAX_LEN];
char sen[MAX_LEN];

scanf(“%c”, &ch);
scanf(“%s\n”, &word);
scanf(“%[^\n]%*c”, &sen);

printf(“%c\n”, ch);
printf(“%s\n”, word);
printf(“%s\n”, sen);

return 0;
}

## What is #Include<stdio.h> ?

#include<stdio.h> is used to included header file in c programming language. It is a Mandetory. It is also Compiler Directives to Include INPUT/OUTPUT related function in our Program. TheĀ stdio.hĀ is a file with “.h” extension which is contain the prototypes [not definition] of standard input-output functions used in c program.

## What is int main() ?

āint mainā means our perform must come thusme whole number at the top of the execution and that we do so by returning zero at the top of the program. zero is that the normal for the āsuccessful execution of the programā.

## What is Printf and Scanf ?

The printf() and scanf() functions area unit used for input and output in C language. each functions area unit inherent library functions, outlined in stdio.h (header file).

## What is Compiler ?

The language processor that reads the whole program written in application-oriented language as a full in one go and interprets it into identical program in machine language is named a Compiler. Example: C, C++, C#, Java. compilers/assemblers area unit themselves package, and reside where they were put in on the pc. that additionally implies that you just will have as many/few of every as you wish.

## How “Playing With Characters” In C program works?

• The #include is a preprocessor command that tells the compiler to include the contents of stdio.h (standard input and output) file in the program.
• The stdio.h file contains functions such as scanf() and printf() to take input and display output respectively.
• If you use the printf() function without writing #include <stdio.h>, the program will not compile.
• The execution of a C program starts from the main() function.
• printf() is a library function to send formatted output to the screen. In this program, printf() displays C Language Welcome To C!!
text on the screen.
• TheĀ return 0;Ā statement is theĀ “Exit status”Ā of the program. In simple terms, the program ends with this statement.

The #include could be a preprocessor command that tells the compiler to incorporate the contents of stdio.h (standard input and output) enter the program.
The stdio.h file contains functions like scanf() and printf() to require input and show output severally.
If you utilize the printf() perform while not writing #include , the program won’t compile.
The execution of a program starts from the main() perform.
printf() could be a library perform to send formatted output to the screen. during this program, printf() displays hello, World! in C text on the screen.
TheĀ return 0;Ā statement is theĀ “Exit status” of the program. In straightforward terms, the program ends with this statement.

#### Hackerrank Answer Playing With Characters

Hello World may be a sample program designed to acquaint users with most programming languages. Beginners ar introduced to the essential syntax of a programing language by learning the way to print out “Hello World” on the device screen. printf(“Hello World”); This line tells the compiler to show the message “Hello World” on the screen. This line is termed an announcement in C. each statement is supposed to perform some task.
