计算某字符出现次数
https://www.nowcoder.com/practice/a35ce98431874e3a820dbe4b2d0508b1
最粗暴就是得到字符大小写，大小写就++
#include<iostream>
#include<string>
#include<algorithm>
using namespace std;
int main() {
string s;
char c,a;
getline(cin,s);
cin >> c;
if (islower(c)) {
a = toupper(c);
}
else {
a = tolower(c);
}
int num = 0;
for (auto it : s) {
if (it == a || it == c) {
num++;
}
}
cout << num;
return 0;
}
