Answer:
PYTHON CODE:
str = input("Enter the first 9 digits of an ISBN-10 as a string : ") # user input
i = 1
checksum = 0 # for total sum
while i < 10:
c = int(str[i - 1]) # getting every digit of the ISBN
c = c * i
checksum += c
i=i+1
checksum=checksum % 11 # getting the last digit of ISBN
ch=checksum
if checksum==10: # if the last digit is 10 then change it to X
ch="X"
print("The Complete 10-Digit ISBN is : ",end="")
print(str,end="") # displaying the 9 digit of ISBN
print(ch) # appending the last digit of ISBN
Explanation:
Answer:
System.out.println("i = " + i + " f = " + f);
Explanation:
The code above has been written using Java's syntax.
To print or display statements to the console, one of the methods to use is the System.out.println() method.
According to the question, the statement to output is i=value-of-i f=value-of-f which is a string of texts.
Note that value-of-i and value-of-f are already stored in variables i and f respectively. Therefore to print them as part of the string text statement, it is important to concatenate them using the "+" operator as follows:
"i = " + i + " f = " + f
If the value of i is 25 and the value of f is 12.34 then the above statement, after successful concatenation reads:
"i = 25 f = 12.34"
which can then be shown on the console using System.out.println() method as follows:
System.out.println("i = " + i + " f = " + f);
Hope this helps!
