The declaration unsigned u indicates:Question 37Select one:u is an unsigned integeru is a characteru is unsigned characteru is unsigned long integer

Break Down the Problem

1. Identify what the declaration unsigned u means in programming.
2. Determine the types of values that u can take.

Relevant Concepts

1. In C/C++ and similar languages, the keyword unsigned specifies that a variable can only hold non-negative values.
2. The type defaults to int unless specified otherwise.

Analysis and Detail

1. An unsigned int, which is indicated by unsigned, allows for a higher positive range compared to a regular signed integer.
2. The declaration unsigned u is shorthand for unsigned int u unless char, long, etc., are directly specified.

Verify and Summarize

The declaration unsigned u implies that u is an unsigned integer by default.

Final Answer

Thus, the correct answer is u is an unsigned integer.
