[每天一点C语言]根据公式C = (5/9)(F-32)打印华氏温度与摄氏温度对应表

#include <stdio.h>
#include <stdlib.h>

int main(){
int fahr, celsius;
int step = 20;
int lower = 0;
int upper = 300;
fahr = lower;
while (fahr <= upper){
celsius = 5 * (fahr - 32) / 9;
printf("%d\t %d\n", fahr, celsius);
fahr += step;
}

system("PAUSE");
}
