#include <stdio.h>
int main() {
char* input = NULL;
char ch;
size_t inputSize = 0;
int len = getline(&input, &inputSize, stdin);
scanf("%c", &ch);
if(ch >= 97){
ch -= 32;
}
char* pCur = input;
int count = 0;
while(pCur - input <= len){
if(*pCur == ch ){
++count;
} else if(*pCur - 32 == ch && *pCur >= 97){
++count;
}
++pCur;
}
printf("%d", count);
return 0;
}
感觉实现的有点复杂
