Write a JavaScript function that extracts a random character from a given string without using .charAt or a local index variable.
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...
