Write a JavaScript function that extracts a random character from a given string without using .charAt or a local index variable.
Homework Answers
function printS(x){
rand = Math.floor((Math.random() * x.length) + 1);
//generating a random variable from 1 to length of the given
string
return x[rand]; //returning a character which is at the random
location. This can be done without using charAt or indexOf
functions
}

Write a C function that receives a character array (string), and it will check the characters of the array to figure out whether the string has a given valid pattern. The required pattern will be given to you. In this function, for instance, you should check if the ascii code of an element of the character array is between a range. The ascii table of all the printable characters will be provided to you. See the last page of this...

2) Write a function stringManip that takes in a character string and returns a character string following these rules: a) any vowel (a, e, i, o, u) is replaced by the character '&' b) any numeric character has 1 added to it (if it was 9, it becomes O instead) (str2num() is useful here) c) all lowercase characters become uppercase d) replace the final character with '!' e) append the length of the string before this step to the end...

Write a recursive function to convert a character string of digits to an integer. Example: convert(“1234”) returns 1234. Hint: To convert a character to a number, subtract the ASCII value ‘0’ from the character. For example, if the string s has only one character, then the function can return the value s[0] – ‘0’.

Python 3: Write a function CharCount, to take a string S and a single character C, and returns the count of C (one letter) in the string S. If the letter of C is not found in S, the function returns -1. You must write your own function to do this and can not use any built-in counting functions. Use the function in main to get two inputs from the user, a sentence and a character, then show the count...

write a function which takes a string argument and a character argument. It should return a truth value (int 0 or 1), 0 if the string does not contain the character, and 1 if the string does contain the character. Do not use a built-in library for this. Again, call this function and its variables whatever you deem appropriate. The main function of the program should accept a single character followed by Enter. Then, it will read lines until the...
