Прямой речи.

When Alec met his friend David he said that he was interested to know what a programming language was. He knew each computer had a repertoire of operations to perform. So he wanted David to explain him if the notions a “machine language” and a “programming language” were the same.

David agreed and began. He said that to perform a task a user must choose the appropriate instructions from the repertoire and sequence them properly. So the means of specifying the instructions and their sequencing was called the “programming language”.

Then Alec guessed that machine language was in reality a programming language and David said that his friend was quite right. He only emphasized that it was the lowest level programming language, the language of binary 1’s and 0’s. Alec remembered that computer hardware understood only a binary program but he wanted if there were any drawbacks to machine level coding.

David answered that the drawbacks were numerous. The most inconvenient thing about the machine level coding was that it took a long time to learn, write and debug. He added that errors would very likely occur and the most unpleasant thing was that corrections were difficult to make.

When Alec asked why Davis replied that the language itself was abstract and perhaps Assembly Language was easier in use. Alec thanked his friend and said he would have to go to the library and read some manual on programming languages.
