Question

Print("please input an integer x: ") x = input() print("please input a second integer y:") y = input() z = x - y print("x - y = " z) what will happen when the program is run? why?

A) It will run successfully and subtract y from x, printing the result.
B) It will result in a syntax error due to the capital "Print" statement.
C) It will run successfully but concatenate x and y as strings instead of subtracting them.
D) It will result in a runtime error due to attempting to subtract two string values.

Answer 1

The program will result in a runtime error because the input() function returns strings and the script attempts to subtract them as if they were integers. It also has a syntax error in the final print statement.

Step-by-step explanation:

When the Python program provided in the question is run, it will result in a runtime error due to attempting to subtract two string values. This is because the input() function in Python always returns a string, and strings cannot be subtracted in the manner shown. In order to perform subtraction, the strings must first be converted to integers using the int() function.

The corrected version of the last part of the code should be:

z = int(x) - int(y)
print("x - y = ", z)

Additionally, there's a syntax error with the print statement, which should have a comma to correctly concatenate string and variable:

print("x - y = ", z)

The program will run successfully but concatenate x and y as strings instead of subtracting them. When the input() function is used, the user's input is treated as a string by default. Therefore, even if the user enters integers, the variables x and y will be assigned string values. When these string values are subtracted, a TypeError will occur.
