AC but have a weird problem
Posted by fyq123 19 Oct 2019 00:51
I use c++,my code is behind. But there is a weird problem . When i define n as int and use cin>>n,the program can't receive the name have more than two word or have symbols like '-'. So i have to define n as a string and transfer the string into a int,why this strange thing happen?

#include<iostream>
#include<string.h>
#include<cstring>
using namespace std;

int main()
{
char room[4][1000][210];
memset(room,0,sizeof(room));
int k=0,nth[4]={0};
char n[10];
cin.getline(n,10,'\n');
int len=10;
while(n[len]=='\0'){len--;}
int temp=1;
for(int i=len;i>=0;i--)
{
k+=(n[i]-48)*temp;
temp*=10;
}

for(int i=0;i<k;i++)
{
char temp[210],temp1[20];
cin.getline(temp,210,'\n');
cin.getline(temp1,20,'\n');

if(temp1[0]=='S')
{
strcpy(room[0][nth[0]],temp);
nth[0]++;
}
else if(temp1[0]=='H')
{
strcpy(room[1][nth[1]],temp);
nth[1]++;
}
else if(temp1[0]=='G')
{
strcpy(room[2][nth[2]],temp);
nth[2]++;
}
else {
strcpy(room[3][nth[3]],temp);
nth[3]++;
}
}
/* omit so this is not a correct solution*/
}
