Question

Write a program that interacts with the user like this:

(1) Carbon monoxide
(2) Hydrocarbons
(3) Nitrogen oxides
(4) Nonmethane hydrocarbons

Enter the pollutant number>> 2
Enter the number of grams emitted per mile>> 0.35
Enter odometer reading>> 40112
Emissions exceed permitted level of 0.31 grams/mile.

Use this table of emissions:
                 Emissions First 50,000miles     Second 50,000 miles
carbonmonoxide 3.4grams/mile              4.2 grams/mile
hydrocarbons 0.31grams/mile                 0.39 grams/mile
nitrogenoxides 0.4grams/mile                   0.5 grams/mile
nonmethane hydrocarbons 0.25grams/mile     0.31 grams/mile

please focus I need program in c !!!! not C++or java:((
please I need full right answer BTW

Explanation / Answer

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
    int pollutantNum;
   long odometerReading;
   float emissions;
    char ch;
   float first50K[4] = {3.4, 0.31, 0.4, 0.25};
   float second50K[4] = {4.2, 0.39, 0.5, 0.31};
   ch = 'n';
   while(1>0)
   {
       printf("(1) Carbon Monoxide ");
       printf("(2) Hydrocarbons ");
       printf("(3) Nitrogen oxides ");
       printf("(4) Nonmethane hydrocarbons ");

       printf(" Enter the pollutant number>>");
       scanf("%d",&pollutantNum);

       printf(" Enter the number of grams emitted per mile>>");
       scanf("%f",&emissions);

       printf(" Enter odometer reading>>");
       scanf("%ld",&odometerReading);

       if(pollutantNum >= 1 && pollutantNum<= 4)
       {
           if(odometerReading <= 50000)
           {
               if(emissions > first50K[pollutantNum-1])
                   printf(" Emissions exceed permitted level of %f grams/mile.",first50K[pollutantNum-1]);
           }
           else
           {
               if(emissions > second50K[pollutantNum-1])
                   printf(" Emissions exceed permitted level of %f grams/mile.",second50K[pollutantNum-1]);
           }
       }
       else
       {
           printf(" Invalid pollutant number entered");
       }

       printf(" Do you want to check another pollutant(enter Y/N)?");
       fflush(stdin);
       ch = getchar();
       if(ch == 'n' || ch == 'N')
           break;
   }
system("PAUSE");  
return 0;
}
