0o4211

0o4211 is a numerical literal. The prefix "0o" indicates that the number is represented in the octal numeral system, which uses base 8. The digits following the prefix are 4, 2, and 1. Therefore, 0o4211 represents the octal number 4211.

To convert this octal number to its decimal (base 10) equivalent, we can use the positional notation of number systems. Each digit's value is multiplied by 8 raised to the power of its position, starting from 0 for the rightmost digit.

In the case of 0o4211:

The rightmost digit, 1, is in the 0th position, so its value is 1 * 8^0 = 1 * 1 = 1.

The next digit, 2, is in the 1st position, so its value is 2 * 8^1 = 2 * 8 = 16.

The next digit, 4, is in the 2nd position, so its value is 4 * 8^2 = 4 * 64 = 256.

The leftmost digit, 2, is in the 3rd position, so its value is 2 * 8^3 = 2 * 512 = 1024.

Summing these values gives the decimal representation: 1024 + 256 + 16 + 1 = 1297.

Thus, 0o4211 in octal is equivalent to 1297 in decimal.

This notation is commonly found in programming languages, particularly those influenced by C, such as Python, where it is used to denote octal integer literals. The "0o" prefix distinguishes it from decimal or hexadecimal representations.
