C++ C+中的类+；：无法将两个旧函数集成到一个"；“类格式”；

更新：我有一个作业，我应该根据键盘上键入的内容打印字母分布。打印应为示例A:5 B:8 C:0。。。等等，这是由函数berakna_histogram_abs和skriv_histogram_abs完成的。从第一次提到的功能中还应打印出字母总数。现在看来，它适用于每个字母的金额正确的情况，但不是总金额始终为0

我的第一个问题是：当字母总数始终为0时，我可以在代码中的哪里找到问题

我不认为有类有什么意义。在
main（）
函数中使用
std:：map
、
std:：getline
和
std:：string
。或者可以使用256个插槽的数组来代替
std:：map
。将字符用作数组的索引：
int counts[256]={0}；/**
