using namespace std;
char vs[1002000][99];
FILE *fp=fopen("D:\\some.txt","r");
int main() {
int i=0;
while (true) {
if (!fgets(vs[i],999,fp)) break;
++i;
}
first of all I would rewrite the C loop to:
int main() {
int i=0;
while (fgets(vs[i],999,fp))
++i;
}
but I think that the difference comes from what you do in the beginning of
the C source:
char vs[1002000][99];
this reserves 99,198,000 bytes so expect a lot of cache trashing in the C
code!
Is there an implementation of f.readlines on the internet somewhere?
interested to see in how they implemented it. I'm pretty sure they did it
smarter than just reserve 100meg of data :)
fclose(fp);
cout << i << endl;
cout << clock()/CLOCKS_PER_SEC << endl;
int m;
cin >> m;
cout << vs[m];
system("pause");
return 0;
}
