Playing With Characters in C - Hacker Rank Solution

Playing With Characters in C - Hacker Rank Solution 

Hello, Coders today we will be solving Playing with Characters in C Hackerrank Problem.

Objective 

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("%s", s). But it accepts strings 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.

NOTE: The statement: scanf("%[*\n]%*c", s); will not work because the last statement will lead a newline character, \n, from the previous line. This can be handled in a variety of ways. One way is to use scanf("\n"); before the last statement. 

Task 

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

Input Format 

First, take a character, ch as input.

Then take a string, s as input.

Lastly, take the sentence sen as input.

Constraints 

Strings for s and sen will have fewer than 100 characters, including the newline.

Output Format 

Print three lines of output. The first line prints the character, ch.

The second line prints the string, s.

The third line line prints the sentence, sen.

Sample Input 

C
Language
Welcome to C!!

Sample Output 

C
Language
Welcome to C!!
