0o1511

The identifier "0o1511" is a numerical literal that represents a specific value. The leading "0o" prefix indicates that the number is expressed in octal (base-8) notation. The subsequent digits "1511" are the octal representation of the number. To convert this octal value to its decimal (base-10) equivalent, one would multiply each digit by the corresponding power of 8 and sum the results. In this case, 1 * 8^3 + 5 * 8^2 + 1 * 8^1 + 1 * 8^0 equals 1 * 512 + 5 * 64 + 1 * 8 + 1 * 1, which results in 512 + 320 + 8 + 1, ultimately equaling 841 in decimal. Therefore, "0o1511" is equivalent to the decimal number 841. This notation is commonly used in programming languages and computing contexts to represent numbers in a different base, often for purposes of memory representation or bit manipulation. The octal system uses digits from 0 to 7.
