tallies win loss and draw

need to be repeating ask user for input if they wanna play again using a yes or no

Answer 1

CODE

#include <stdio.h> // Standard IO

#include <stdlib.h> // other stuff

#include <time.h>

#include <string.h>

//This should add weighted random function to "The Elite Noob"'s code, stolen from above code because it does calculation so well

//closest I could make it to original but without pointless attempt to make code look smaller than above code by putting code on the same lines

int rand_i(int n)

{

  int rand_max = RAND_MAX - (RAND_MAX % n);

  int ret;

  while ((ret = rand()) >= rand_max);

  return ret/(rand_max / n);

{

  int i, sum, r;

  for (i = 0, sum = 0; i < len; sum += tbl[i++]);

  if (!sum) return rand_i(len);

  r = rand_i(sum) + 1;

  for (i = 0; i < len && (r -= tbl[i]) > 0; i++);

  return i;

OUTPUT

1
Comp Played: Paper
You Played: Rock
Sorry, You Lost!
Do you want to continue (y/n)? y

Please type in 1 for Rock, 2 For Paper, 3 for Scissors
3
Comp Played: Rock
You Played: Scissors
Sorry, You Lost!
Do you want to continue (y/n)? y

Please type in 1 for Rock, 2 For Paper, 3 for Scissors
2
Comp Played: Rock
You Played: Paper
Yay, You Won!
Do you want to continue (y/n)? N
Wins = 1, ties = 0, lost = 2
