没找到c语言正确代码，出一个:
#include <stdio.h>
#include <ctype.h>int main(){
char s[1010];
char c;
fgets(s, 1010, stdin);
c = getchar();
if(isupper(c)) c = tolower(c);
int count = 0;
for(int i = 0; s[i] != '\0';i++){
if(isalpha(s[i])) s[i] = tolower(s[i]);
if(c == s[i]) count++;
}
printf("%d",count);
return 0;
}
