Question

write a C program that takes a floating-point value from the command line. This value is interpreted to be a fuel consumption reading in Miles/Gallon. The program returns the fuel consumption in Liters per 100 Kilometer.

The prototype declaration of the function implementing this looks like this:

float mpg_to_lp100k(float mpg);

Answer 1

Solution:

#include<stdio.h>
#include<stdlib.h>
float mpg_to_lp100k(float mpg)
{
   float ans=(1.60934/3.78541)*mpg;
   float result=(1/ans)*100.00;
   return result;
}
int main(int argc,char *argv[])
{
   float mpg,result;

   mpg=atof(argv[1]);  
   result=mpg_to_lp100k(mpg);  
  
   printf("The fuel consumption in Litres per 100 Kilometers: %f\n",result);
   return 0;
}

Output:
