Chapter 3.2, Problem 12SCP
Explanation of Solution
Given
//Create a class
public class Temperature
{
//Define the method
public static void main(String[] args)
{
//Declare and initialize the variable
double tempf =98.6;
double tempc=0.0;
//Call the method
ftoc(tempf , tempc) ;
//Print the value of tempc
System.out.println("Body temp in C is : "+tempc);
}
/*Define the method that converts Fahrenheit temperatures to Celsius*/
public static void ftoc (double tempf , double tempc )
{
//Calculate the value of tempc
tempc=(tempf-32)*5/9;
}
}
Mistake:
- The value of “tempc” is changed inside the scope of “ftoc()” function and this does not affect the value of the variable “tempc” in the scope of “main()” function.
Correction:
- The given program produces the output as,
Body temp in C is : 0.0
- The highlighted part in the given program denotes the value of “tempc” in “main()” function...
