Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
#include <string.h>

#define WEATHER_LEN 8

int main(void) {
    char weather[WEATHER_LEN];
    int len;

    fgets(weather, WEATHER_LEN, stdin);
    len = strlen(weather);
    if (weather[len-1] == '\n') {
        weather[len-1] = '\0';
        len--;
    }

    if (strncmp(weather, "Sunny", 5) == 0) {
        printf("Cloudy\n");
    } else if (strncmp(weather, "Cloudy", 6) == 0) {
        printf("Rainy\n");
    } else if (strncmp(weather, "Rainy", 5) == 0) {
        printf("Sunny\n");
    } else {
        printf("Illegal weather: %s\n", weather);
    }

    return 0;
