题意:替换单词,这个题不难,但写题解想想就是泪啊TAT,最大要注意的地方就是要替换彻底,就是替换完之后如果可以替换接着替换,其次,一定要一个单词一个单词的替换。
剩下的看代码吧:
#include
#include
#include
using namespace std;
int main()
{
double f1,f2,fans;
int i1,i2,ians;
while(~scanf("%lf %c %lf",&f1,,&c,&f2))
{
bool a = 1,b = 1,c = 1;
i1 = f1;
i2 = f2;
if(fabs(f1 - i1) < 0.001)
a = 0;
if(fabs(f2 - i2) < 0.001)
b = 0;
if(!a && !b)
{
if(c == '+')
{
fans = f1 + f2;
ians = i1 + i2;
if(fabs(fans - ians) < 0.001)
c = 0;
}else if(c == '*')
{
fans = f1 * f2;
ians = i1 * i2;
if(fabs(fans - ians) < 0.001)
c = 0;
}
}
if(a)
cout << "first number too big" << endl;
if(b)
cout << "second number too big" << endl;
if(a || b || c)
{
cout << "result too big" << endl;
}
}
return 0;
}
