Fisher yates shuffle in c

WebSum up the weights. Generate a random number from 0 to the sum. Iterate through the objects, subtracting their weight from the sum until the sum is non-positive. Remove the object from the list, and then add it to the end of the new list. Items 2,4, and 5 all take n time, and so it is an O (n^2) algorithm. http://duoduokou.com/c/34797343302011392307.html
