Playing With Characters

---

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 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 .

---

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: The statement: scanf("%[^\n]%*c", s); will not work because the last statement will read 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 next line. In the last line print the sentence, sen .

---

Solution:

#include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> int main()  {     char ch;     char s[100];     char sen[100];          scanf("%c", &ch);     scanf("%s\n", &s);     scanf("%[^\n]%*c", &sen);          printf("%c\n", ch);     printf("%s\n", s);     printf("%s\n", sen);     return 0; }
