/*
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

You can take a string as input in C using scanf("%s", 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.
Note: After inputting the character and the string, inputting the sentence by the above mentioned statement won't work. This is because, at the end of each line, a new line character (\n) is present. So, the statement: scanf("%[^\n]%*c", s); will not work because the last statement will read a newline character from the previous line. This can be handled in a variety of ways and one of them being: scanf("\n"); before the last statement.

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

Input Format
- First, take a character,  as input.
- Then take the string,  as input.
- Lastly, take the sentence  as input.

Output Format
- 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.
