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
