Question
In c++ how can I read this datafile in for use?
I want a user to be prompted a random capital, pop, size, zone, nickname, or bordering states. Then they can try and guess the state or state symbol.
I used: input.ignore(10000,' ');
input.ignore(10000,' ');
input.ignore(10000,' '); to ignore first 3 lines of junk code.
Symbol Capital Nickname 0000000000111111111122222222223333333333444444444455555555556666666666777777777788888888889999999999000000 0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345 Alabama Heart of Dixie Last Frontier Grand Cany Natura.l FL,GA,MS, TN none CA, CO,NM, NV, UT LA,MO,MS,oK,TN, TX AK Juneau 48 Arizona 3229CST Little Rock Sacramento ansas ornia Colorado Connecticut CT Centennial State Constitution State nver KS,NE,NM, OK, UT,WY,AZ EST EST laware Tallahassee 3 22 EST/CST Everglade State NC,SC,TN, FL,AL none MT ,NV,0R, UT, WA,WY IN,KY,MO,WI, IA IL,MI,KY,OH IL,WI,Mo,NE, SD,MN 39 14 PST/MST Gem State Illino Indiana Indianapolis 16 38 EST/CST Hoosier State Kansas Kentucky KS 34 15CST/MST America's Bread Basket MO, NE,OK, CO Frankfor 26 37EST/CST Bluegrass State MO,0H, TN, VA,WV, IL, IN MS, TX,AR Baton Rouge 25 31 CST EST EST EST Louisiana Mary Massachusetts MA Pine Tree State Chesapeake State Baked Bean State PA, VA,WW,DE NH, VT, CT, RI,NY Boston ansin 10 11 EST/CST Great Lakes State Minnesota Mississippi Missouri Montana Nebraska Nevada ND,SD,WI, IA AL,AR, LA, TN IA,NE,KS,oK,AR, TN,KY,IL ND,SD,WY, ID SD,WY, CO,KS,MO, IA CA,AZ,UT.

Explanation / Answer
we use the fact that data is properly indented.
code:
#include <bits/stdc++.h>
using namespace std;
string trim(string s){
int ind=s.length();
for(int i=s.length()-1;i>=0;i--){
if(s[i]!=' '){
ind=i;
break;
}
}
return s.substr(0,ind+1);
}
int main(){
ifstream inf;
inf.open("input.txt");
string s;
//remove first three lines by just reading them
getline(inf,s);
getline(inf,s);
getline(inf,s);
//variable to store data of each state
string state;
string sym;
string cap;
int pop;
int size;
string zone;
string nickname;
vector<string> border_states;
while(getline(inf,s)){
state=trim(s.substr(0,15));
sym=s.substr(15,2);
cap=trim(s.substr(23,14));
stringstream ss;
ss<<s.substr(38,7);
ss>>pop>>size;
zone=trim(s.substr(49,9));
nickname=trim(s.substr(58,25));
string bs=trim(s.substr(83));
if(bs!="none"){
int i=0;
while(i<bs.length()){
border_states.push_back(bs.substr(i,2));
i=i+3;
}
}
// cout<<state<<" "<<sym<<" "<<cap<<" "<<pop<<" "<<size<<" "<<zone<<" "<<nickname<<" "<<bs<<endl;
}
return 0;
}
