使用计数器在数组中搜索用户输入字

Question

我要做的是创建一个具有set数组的程序，程序要求用户输入一个单词，程序找到单词并输出它被使用了多少次。因此，例如我设置的数组（每个字母都在它自己的数组编号中）是“热量理论”，因为它在文本中有几个“the”。我希望用户输入'the'并将输出设置为2（因为第一个是大写的）。或者，如果用户想要输入'e'，他将得到3。

我有阵列设置，但我仍然在寻找一种设置程序的方法，这样如果用户输入多个字母，它一次可以查看多个字母。

我假设我需要为扫描仪输入.length，在其周围输入计数器，然后让阵列随之移动。我会更多地了解这一点，如果你们能帮助我，我会很感激。
