c - 调试时断言错误

Question

我目前正在编写允许两个人玩骰子游戏的代码。您“掷”了两个骰子，如果掷出双骰，您将获得 5 分，除非: 1) 双骰是两个 6，此时您将获得 25 分；或 2) double 是两个三分，此时整个玩家的得分都被删除。

目前，我在调试时遇到了断言错误。具体来说，它表示格式 != nullptr。

我不太确定这里发生了什么。任何帮助将不胜感激!

这是我的代码。

/*This program allows users to play the dice game Fifty, where they roll a pair of dice to obtain doubles.
  Any set of doubles except for threes or sixes earn the player 5 points. Sixes earn the player 25 points.
  If the player rolls a pair of threes, their entrie score will be reset to 0. Play continues until one
  player reaches fifty points. At this point, the game ends and the players have the chance to start a new
  game.*/

我弄乱了我的 scanf_s 参数，所以错误已修复!
