To convert a non-negative integer to hexadecimal in a program, the Python function hex(integer) should be used. It returns a string with the hexadecimal representation prefaced by '0x'. The user needs to be prompted for a non-negative integer, checked for the input's validity, and then the hex function can be used to provide the final output.
To convert a non-negative integer to its hexadecimal representation in a program, option (a) hex(integer) is correct. This function takes an integer and returns the hexadecimal version of it as a string starting with '0x'. Below is a simple Python program that demonstrates this: number = int(input("Enter a non-negative integer: ")) if number >= 0: hexadecimal = hex(number) print("Hexadecimal representation:", hexadecimal) else print("Please enter a non-negative integer.")
In the example above, the user is prompted to enter an integer. The program checks if the input is non-negative, then calls the hex function and outputs the result. If the user enters a negative number, the program will ask the user to try again.
To convert an integer to hexadecimal, use the hex function. Remember to validate user input to ensure non-negative integers are processed.
