Question

Write a C program that asks the user to enter a value for distance. The input must be entered as value and unit of length (km or miles), like so: Xxx.xx k <--- for distance in km <--- for distance in miles or XXX.xx m If the unit is km (k), the program prints the equivalent distance in miles. If the unit is miles (m), the program prints the equivalent distance in km. Note: miles = 0.62137 * km

Answer 1

#include <stdio.h>

int main()
{
//variable declaration
float distance;
char unit;
  
//get user input
printf("Enter a value for distance and unit of length: ");
scanf("%f %c", &distance, &unit);
  
//check the unit
if(unit=='k')
{
//calculate miles
float miles = distance / 0.62137;
  
//display equivalent miles
printf("\nThe equivalent distance in miles is = %.2f miles", miles);
}
else if(unit=='m')
{
//calculate kilometer
float km = distance * 0.62137;
  
//display equivalent kilometer
printf("\nThe equivalent distance in kilometer is = %.2f km", km);
}
return 0;
}

OUTPUT:

RUN 1:

Enter a value for distance and unit of length: 1 k

The equivalent distance in miles is = 1.61 miles

RUN 2:

Enter a value for distance and unit of length: 1 m

The equivalent distance in kilometer is = 0.62 km
