计算某字符出现次数

#include <iostream>
using namespace std;
int main() {
string input1;
char input2;
int count = 0;
getline(cin, input1);
cin >> input2;
input2 = tolower(input2);
for (auto ch : input1) {
if (tolower(ch) == input2)
count++;
}
cout << count << endl;
}
// 64 位输出请用 printf("%lld")
思路:首先读取输入字符串和目标字符串,然后将目标字符串转化为小写,然后遍历输入字符串,统计目标字符串的出现次数
