      • Write a C callable assembler function that counts the number of characters in a string. The function should work for any string and character. The address of the string and character to be counted are passed as arguments according to the C function prototype: int count (char *string, char c);
      • I divide the string up in blocks of four bytes each (32 bits), and add 4 to EAX. Once I hit a completely NULL block, I roll back the count of EAX by 4 bytes, and then calculate the final block's size one byte at a time. It only works using ASCII characters, and is limited to 32 bit computing (though that can be easily upgraded to 64 bit soon).
      • Consider breaking it up into 5 pieces and use piping: read in text and print the words one per line in lowercase, sort to bring identical words together, remove duplicates and print count, sort by count.

    • The hex characters are then stored as the two byte string representation of the characters. Often, some kind of separator is used to make the encoded data easier for human reading. With 8 bits converted to three characters and each character stored as 1-4 bytes you might use up to 12 bytes (or even more in some cases) for each byte of information.

    • String and Character Array. String is a sequence of characters that is treated as a single data item and terminated by null character '\0'. Remember that C language does not support strings as a data type. A string is actually one-dimensional array of characters in C language. These are often used to create meaningful and readable programs.

    • Characters that cannot be placed in string literals can be placed in string expressions using the :CHR: unary operator. Any ASCII character from 0 to 255 is permitted. The value of a string expression cannot exceed 5120 characters in length. It can be of zero length. •Given two strings x and y, we wish to compute their (LCS). If we delete some characters from x and some characters from y, and the resulting two strings are equal, we call the resulting string a common subsequence. The LCS problem is to find a common subsequence of two strings that is as long as possible.
