The implementation of English-Chinese dictionary Code

English-Chinese Dictionary

Design process

Read the contents of the Word file---Parse file contents--Search by input

1. First use a fixed string to receive the contents of the file read, and then transferred to the array, easy to handle later

2. Iterate through the array, add even lines as key, odd rows as value into Dictionary 1 (here refers to a class in the OC language) as a dictionary of English-Chinese, key and value in turn in Dictionary 2

As a dictionary of Chinese to English, call the Keyforvalue method to remove value. (The dictionary file content format is as follows:

#a

Trans:art. A; the letter A

#a. M.

Trans:n. Morning

#a/C

Trans:n. Current account @ current: come-and-go; Contact [Email protected] Current account

#aardvark

Trans:n. Soil Pig

#aardwolf

Trans:n. Coyote

#aasvogel

Trans:n. A kind of bald eagle

#abaci

Trans:n. Abacus

#aback

Trans:ad. Back to the back of the land

#abacus

Trans:n. Abacus

#abaft

Trans:ad. @prep to the stern. In... After

#abalone

Trans:n. Abalone

).

3. Remove all keys from the dictionary, compare the for loop with the input characters, and compare only the substring of key.

The following are the specific code implementations:
