Q. Program to count the total number of punctuation characters exists in a string.

In this program, all the subsets of the string need to be printed. The subset of a string is the character or the group of characters that are present inside the string. For example, all possible subsets of a string “FUN” will be F, U, N, FU, UN, FUN.

Algorithm

Define a string.
If any character in the string is matched with (! , . , ‘ , – , ” , ? , ; ) , increment the count by 1.
Print the count.

Complexity:

O(n)

Solution

Python

  count = 0;  str = “Good Morning! Mr. James Potter. Had your breakfast?”;  for i in range (0, len (str)):       #Checks whether given character is a punctuation mark      if str[i] in (‘!’, “,” ,”‘” ,”;” ,”””, “.”, “-” ,”?”):          count = count + 1;            print (“Total number of punctuation characters exists in string: “);  print (count);  

Output:

Total number of punctuation characters exists in string:   4

C

  #include <stdio.h>  int main ()  {     int i, countPuncMarks = 0;     char str [] = “Good Morning! Mr. James Potter. Had your breakfast?”;        //Checks whether given character is punctuation mark     for(i = 0; i < strlen(str); i++){         if(str[i] == ‘!’ || str[i] == ‘,’ || str[i] == ‘;’ || str[i] == ‘.’ || str[i] == ‘?’ ||          str[i] == ‘-‘ || str[i] == ”’ || str[i] == ‘”‘ || str[i] == ‘:’) {                  countPuncMarks++;              }     }     printf(“Total number of punctuation characters exists in string : %d “,countPuncMarks);     return 0;  }  

Output:

Total number of punctuation characters exists in string: 4

JAVA

  public class punctuation {      public static void main (String [] args) {          //Stores the count of punctuation marks          int countPuncMarks = 0;          String str = “Good Morning! Mr. James Potter. Had your breakfast?”;          for (int i = 0; i < str.length(); i++) {                  //Checks whether given character is punctuation mark              if(str.charAt(i) == ‘!’ || str.charAt(i) == ‘,’ || str.charAt(i) == ‘;’ || str.charAt(i) == ‘.’ ||        str.charAt(i) == ‘?’ || str.charAt(i) == ‘-‘ ||                      str.charAt(i) == ”’ || str.charAt(i) == ‘”‘ || str.charAt(i) == ‘:’) {                  countPuncMarks++;              }          }          System.out.println(“Total number of punctuation characters exists in string: ” +        countPuncMarks);      }  }  

Output:

Total number of punctuation characters exists in string: 4

C#

  using System;                  public class Program  {      public static void Main ()      {          //Stores the count of punctuation marks          int countPuncMarks = 0;          string str = “Good Morning! Mr. James Potter. Had your breakfast?”;          for (int i = 0; i < str.Length; i++) {           //Checks whether given character is punctuation mark           if(str[i] == ‘!’ || str[i] == ‘,’ || str[i] == ‘;’ || str[i] == ‘.’ || str[i] == ‘?’ || str[i] == ‘-‘ ||                      str[i] == ”’ || str[i] == ‘”‘ || str[i] == ‘:’) {                  countPuncMarks++;              }          }          Console.WriteLine(“Total number of punctuation characters exists in string: ” + countPuncMarks);      }  }  

Output:

Total number of punctuation characters exists in string: 4

PHP

  <!DOCTYPE html>  <html>  <body>  <?php      //Stores the count of punctuation marks      $count = 0;      $str = “Good Morning! Mr. James Potter. Had your breakfast?”;      for($i = 0; $i < strlen($str); $i++) {          //Checks whether given character is punctuation mark          if($str[$i] == ‘!’ || $str[$i] == ‘,’ || $str[$i] ==     ‘;’ || $str[$i] == ‘.’  || $str[$i] == ‘?’ || $str[$i] == ‘-‘ || $str[$i] == ”’ || $str[$i] ==   ‘”‘ || $str[$i] == ‘:’) {                  $count++;              }          }      echo “Total number of punctuation characters exists in string : “;      echo $count;  ?>  </body>  </html>  

Output:
