温度转换器使用c语言中的函数编程

Question

#include <stdio.h>
int converttemperature(int f,int c)
int main()
{
int farenheit, celcius, upper, lower, step;
upper=300; lower=0; step=20;
farenheit=lower;
while(farenheit<=upper) 
{
converttemperature(farenheit, celcius);
printf("%dt %dn", farenheit, celcius);
farenheit = farenheit+step;
}

return 0;
}
int converttemperature(int f, int c)
{ 
int f,c;
c = 5 * (f-32) / 9;
return c;
}

Answer 1

#include <stdio.h>
int converttemperature(int f);
int main(void)
{
int farenheit, celcius, upper, lower, step;
upper=300; lower=0; step=20;
farenheit=lower;
while(farenheit<=upper) 
{
celcius = converttemperature(farenheit);
printf("%dt %dn", farenheit, celcius);
farenheit = farenheit+step;
}

return 0;
}
int converttemperature(int f)
{ 
int c;
c = 5 * (f-32) / 9;
return c;
}
