题意:给定文本,求有几个doge,不区分大小写
思路:水题,直接一个个读字符每次判断即可
代码:
#include <stdio.h> #include <string.h> char c; char a[5]; int main() { a[5] = '\0'; int ans = 0; while ((c = getchar()) != EOF) { if (c >= 'a' && c <= 'z') c -= 32; a[3] = c; if (strcmp(a, "DOGE") == 0) ans++; for (int i = 0; i < 3; i++) a[i] = a[i + 1]; } printf("%d\n", ans); return 0; }
