CODE:

<!DOCTYPE html>
<html>
<head>
   <title>Alnum Count</title>
</head>
<body>
<p id="input"></p> <! -- to print input-->
<p id="count"></p> <! -- to print count -->
<script>//script tag to write the function.
var string=prompt("Enter string : ");//taking input from the user
document.getElementById("input").innerHTML="The user input is : "+string;//printing the input.
var count=alnum(string);//function returnds the count of alpha numeric characters.
//Printing the count returned from the function.
document.getElementById("count").innerHTML = "The count of alpha numberic characters is : "+count;
//function that returns the count of alpha numeric.
function alnum(str) {
   var i;//loop variable.
   var count=0;//count variable.
   for(i=0;i<str.length;i++)//loop iterates through the string.
   {
       //condition to check number or lowercase alphabet or uppercase alphabet.
       if((str[i]>='0' && str[i]<='9') ||(str[i]>='a' && str[i]<='z') ||(str[i]>='A' && str[i]<='Z'))
       {
           ++count;//increment count if condition satisfied
       }
   }
   return count;//returning the count.

}
</script>

Complete the function, MycountWords in C++, which will count the number of words in a string. We will have different word separators(such as newline(\n), spaces, special symbols(? | \ , . : ;) ) That will separate the words in the giving istringstream. Remember if a words is separated by a hyphen and followed by a new line, they're still one word. The function has an option to be sensitive to case and also avoid duplicates. for duplicates, this is...

PYTHON Define a function named variousChanges(...) which receives one string (origst) (with letters, digits or special characters), possibly empty, and returns a new string containing the following. a) in those positions where the original string has an even digit, the corresponding character in the new (returned) string should have the string digit '0' b) in those positions where the original string has a vowel letter (upper or lower case), the new (returned) string should have the letter 'V'. Note that...

The problem is, after appending all chars in a string and try to count clusters of values in that string, I get seg fault. I feel like my logic behind is ok, but I am not sure what I did wrong.

In PYTHON: Write a function that receives an encrypted string and decrypts it as follows. The decryption does not change the lowercase letters ‘e’, ‘w’, and ‘l’ (lowercase L). For any other character, we change it to a number using ord(). We then take the number to a power of 19, and then find the remainder after diving by 201. Finally, we take the character corresponding to the number we obtained (using chr()). For example, assume that we receive the...
