Answer 1

供参考：

#include <stdio.h>
int main()
{
    int lower, upper, fahr, k;
    float celsius;
    scanf("%d %d", &lower, &upper);

    if (lower < 1 || upper < 1 || lower > upper || lower > 100 || upper > 100)
        printf("Invalid.");
    else
    {
        printf("fahr celsius\n");
        for (fahr = lower, k = 0; fahr <= upper; fahr += 2)
        {
            celsius = 5.0 * (fahr - 32) / 9.0;
            printf(k++ ? "\n%d%6.1f" : "%d%6.1f", fahr, celsius);
        }
    }
    return 0;
}
