Here is my code so far. I just can't get the last 3 lines. I need to accept only text that says Total or Gas. How would I do that? I've looked up and read a lot of stuff but everything I tries doesn't work haha. any help would be great.
Code:#include <iostream> #include <string> using namespace std; int main() { int miles_per_year; double gallon_gas; double hybrid_cost; int hybrid_mpg; double hybrid_resale; double cost_nonhybrid; int non_hybrid_mpg; double nonhybrid_resale; int buying_crit; cout <<"Please answer the following questions.\n" << endl; do { cout <<"The estimated miles driven per year?" << endl; cin >> miles_per_year; if(miles_per_year < 0) cout <<"Please enter a positive value." << endl; } while(miles_per_year < 0); do { cout <<"The estimated price of a gallon of gas?" << endl; cin >> gallon_gas; if(gallon_gas < 0) cout <<"Please enter a positive value." << endl; } while(gallon_gas < 0); do { cout <<"The cost of a hybrid car?" << endl; cin >> hybrid_cost; if(hybrid_cost < 0) cout <<"Please enter a positive value." << endl; } while(hybrid_cost < 0); do { cout <<"The efficiency of the hybrid car in miles per gallon?" << endl; cin >> hybrid_mpg; if(hybrid_mpg < 0) cout <<"Please enter a positive value." << endl; } while(hybrid_mpg < 0); do { cout <<"The estimated resale value for a hybrid after 5 years?" << endl; cin >> hybrid_resale; if(hybrid_resale < 0) cout <<"Please enter a positive value." << endl; } while(hybrid_resale < 0); do { cout <<"The cost of a non-hybrid car?" << endl; cin >> cost_nonhybrid; if(cost_nonhybrid < 0) cout <<"Please enter a positive value." << endl; } while(cost_nonhybrid < 0); do { cout <<"The efficiency of the non-hybrid car in miles per gallon?" << endl; cin >> non_hybrid_mpg; if(non_hybrid_mpg < 0) cout <<"Please enter a positive value." << endl; } while(non_hybrid_mpg < 0); do { cout <<"The estimated resale value for a non-hybrid after 5 years?" << endl; cin >> nonhybrid_resale; if(nonhybrid_resale < 0) cout <<"Please enter a positive value." << endl; } while(nonhybrid_resale < 0); cout <<"Would you like results sorted by lowest gas consumption(\"gas\")\n or lowest total cost(\"total\")?" << endl; cout <<"Please enter either \"gas\" or \"total\" for how results are to be sorted." << endl; cin >> buying_crit; system("pause"); return 0; }
