Program to count the total number of characters in a string

Explanation

In this program, we need to count the number of characters present in the string.

To count the number of characters present in the string, we will iterate through the string and count the characters. In above example, total number of characters present in the string are 19.

Algorithm

Define a string.
Define and initialize a variable count to 0.
Iterate through the string till the end and for each character except spaces, increment the count by 1.
To avoid counting the spaces check the condition i.e. string[i] != ‘ ‘.

Solution

Python

  string = “The best of both worlds”;  count = 0;     #Counts each character except space  for i in range(0, len(string)):      if(string[i] != ‘ ‘):          count = count + 1;     #Displays the total number of characters present in the given string  print(“Total number of characters in a string: ” + str(count));  

Output:

 Total number of characters in a string: 19

C

  #include <stdio.h>  #include <string.h>     int main()  {      char string[] = “The best of both worlds”;      int count = 0;            //Counts each character except space      for(int i = 0; i < strlen(string); i++) {          if(string[i] != ‘ ‘)              count++;      }            //Displays the total number of characters present in the given string      printf(“Total number of characters in a string: %d”, count);         return 0;  }  

Output:

Total number of characters in a string: 19

JAVA

  public class CountCharacter  {      public static void main(String[] args) {          String string = “The best of both worlds”;          int count = 0;                    //Counts each character except space          for(int i = 0; i < string.length(); i++) {              if(string.charAt(i) != ‘ ‘)                  count++;          }                    //Displays the total number of characters present in the given string          System.out.println(“Total number of characters in a string: ” + count);      }  }  

Output:

Total number of characters in a string: 19

C#

  using System;                        public class CountCharacter  {      public static void Main()      {          String string1 = “The best of both worlds”;          int count = 0;                    //Counts each character except space          for(int i = 0; i < string1.Length; i++) {              if(string1[i] != ‘ ‘)                  count++;          }                    //Displays the total number of characters present in the given string          Console.WriteLine(“Total number of characters in a string: ” + count);      }  }   

Output:

Total number of characters in a string: 19

PHP

  <!DOCTYPE html>  <html>  <body>  <?php  $string = “The best of both worlds”;  $count = 0;     //Counts each character except space  for($i = 0; $i < strlen($string); $i++) {      if($string[$i] != ‘ ‘)          $count++;  }     //Displays the total number of characters present in the given string  print(“Total number of characters in a string: ” . $count);  ?>  </body>  </html>  

Output:

 Total number of characters in a string: 19
