Playing with Characters


Problem Statement :


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 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.


Input Format:

First, take a character, ch as input.
Then take the 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 prints the sentence, sen.

                            Solution in C :

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

int main() 
{
    char ch,s[10],sen[100];
    scanf("%c", &ch);
    scanf("%s", &s);
    scanf(" %[^\n]%*c", &sen);
    printf("%c\n%s\n%s",ch,s,sen);
    return 0;
}

Find the Running Median

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.
