Question

In the LC-3, how many memory words are used to store the string below? (NOTE: The quotes are not part of the string.) "I want my...I want my...I want my MTV!"

Answer 1

Answer:.......

Four memory words were used to store the string.

Explanation:

This is because there were just four words which are ; I, want , my , MTV.

Answer 2

Answer:

39

Explanation:

In LC-3 one character per memory location is stored and each string is ended with NULL character.

Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.

It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students.

The LC-3 was developed by Yale N. Patt at the University of Texas at Austin and Sanjay J. Patel at the University of Illinois at Urbana–Champaign. Their specification of the instruction set, the overall architecture of the LC-3, and a hardware implementation can be found in the second edition of their textbook. Courses based on the LC-3 and Patt and Patel's book are offered in many computer engineering and computer science departments.

While it has not been implemented on a physical chip, the LC-3 can be used in simulation on Linux/Unix, Mac OS X and Windows environments. The simulation tools include an assembler with support for computerized offset computation with labels and the insertion of constants, strings, and blank memory locations into a block of assembly code. There is also a convention for using the C language on the LC-3. A sample assembler, compiler, and simulator are provided by McGraw-Hill
