[单项选择]We all know that programming language is the system of syntax, grammar, and symbols or words used to give instructions to a computer. Because computers work with binary numbers, first-generation languages, called machine languages, required the writing of long strings of binary numbers to represent such operations as add, subtract, and compare. Later improvements allowed octal, decimal, or hexadecimal representation of binary strings. It is difficult to write error-free programs in machine language; many languages have been created to make programming easier and faster. Symbolic, or assembly, languages-- second-generation languages-- were introduced in the early 1950s. They use simple mnemonics such as "A" for add or "M" for multiply, which are translated into machine language by a computer program called an assembler. An extension of such a language is the macro instruction, a mnemonic (such as "READ" ) for which the assembler substitutes a series of simpler mnemonics. In the mid-1950
A. it is used in designing software

C. is should be translated into the computer language by software
