[問題] C 語言考題請教
各位好
我看不出來以下兩個 function 有什麼不同，請各位指教。
1.Do cmp1 and cmp2 print the same message for all possible inputs?
if not , please provide a case where they print it.
1.Do cmp1 and cmp2 return the same value for all possible inputs?
if not , please provide a case where they return it.
#define ABS(n) ((n<0)? -n:n)
int cmp1(int a , int b)
{
int result;
a=(a<0) ? -a: a;
b=(b<0) ? -b: b;
result=(a==b);
if(result)
printf("The absolute values of %d and %d are the same.",a,b);
else
printf("The absolute values of %d and %d are different.",a,b);
return result;
}
int cmp2(int a , int b)
{
int result=(ABS(a)==ABS(b));
if(result)
printf("The absolute values of %d and %d are the same.",a,b);
else
printf("The absolute values of %d and %d are different.",a,b);
return result;
}
