Type the program's output
number = 14
print('Decimal - 14. Binary - {:b}'.format(number))
Answer (1)
The code assigns the decimal value 14 to the variable number .
The code converts the decimal value to its binary representation, which is 1110.
The code prints a formatted string that includes both the decimal and binary values.
The final output is: Decimal - 14. Binary - 1110
Explanation
Problem Analysis The provided Python code assigns the value 14 to the variable number . The code then uses the print function along with string formatting to display the decimal and binary representations of number . The format specifier {:b} is used to convert the decimal number to its binary equivalent.
Decimal Value The decimal value of the variable number is simply 14.
Binary Conversion To find the binary representation of 14, we can express it as a sum of powers of 2: 14 = 8 + 4 + 2 = 2 3 + 2 2 + 2 1 = 1 ⋅ 2 3 + 1 ⋅ 2 2 + 1 ⋅ 2 1 + 0 ⋅ 2 0 Thus, the binary representation of 14 is 1110.
Output String The print statement outputs the string 'Decimal - 14. Binary - ' followed by the binary representation of 14, which is 1110.
Final Answer Therefore, the program's output is: Decimal - 14. Binary - 1110
Examples
Binary numbers are fundamental in computer science. For example, when storing data, computers use binary to represent numbers, text, images, and instructions. Understanding how to convert between decimal and binary is crucial for anyone working with computers, as it helps in understanding how data is stored and manipulated at the lowest level. For instance, representing the number of available memory slots in a computer system or the number of processors can be efficiently done using binary.
