back to board#include <iostream>
#include <string.h>
int main() {
char grif[1001][202],sliz[1001][202],huff[1001][202],rave[1001][202],name[202],group[20];
int n,i,gcur=0,scur=0,hcur=0,rcur=0;
std:: cin >> n;
while( n>=0 )
{
std:: cin.getline(name,202);
std:: cin.getline(group,20);
if(!strcmp(group,"Slytherin")) { strcpy(sliz[scur],name); scur++; }
if(!strcmp(group,"Hufflepuff")) { strcpy(huff[hcur],name); hcur++; }
if(!strcmp(group,"Gryffindor")) { strcpy(grif[gcur],name); gcur++; }
if(!strcmp(group,"Ravenclaw")) { strcpy(rave[rcur],name); rcur++; }
--n;
}
std::cout<<"Slytherin:\n";
for( i=0; i<scur; ++i ) std:: cout << sliz[i] << '\n';
std::cout<<'\n';
std::cout<<"Hufflepuff:\n";
for( i=0; i<hcur; ++i ) std:: cout << huff[i] << '\n';
std::cout<<'\n';
std::cout<<"Gryffindor:\n";
for( i=0; i<gcur; ++i ) std:: cout << grif[i] << '\n';
std::cout<<'\n';
std::cout<<"Ravenclaw:\n";
for( i=0; i<rcur; ++i ) std:: cout << rave[i] << '\n';
std::cout<<'\n';
return 0;
} This is madness! Don't write such code =)
int main()
{
int students;
cin >> students;
map< string, vector<string> > house_to_students;
for (int student = 0; student < students; student++)
{
cin.ignore();
string student_name;
getline(cin, student_name);
string house;
cin >> house;
house_to_students[house].push_back(student_name);
}
for (auto house : { "Slytherin", "Hufflepuff", "Gryffindor", "Ravenclaw" })
{
cout << house << ":" << endl;
for (auto student : house_to_students[house])
cout << student << endl;
cout << endl;
}
} It happened bcs of cin function
In the input they give n and endl after n;
so, somehow getline reads this endl as a string, so you can do this
insted of "cin>>n"
use "scanf("%d\n", &n); |
