Where does HUC stop at Shanghai New International Expo Center
driving to the International Expo Center
must be very congested
it's better to drive to the place where there is a subway
park the car in the nearby parking lot
and then take the subway to get there
it's much more convenient
you can use the map to search
to see the nearest bus or subway
because you don't know which entrance you enter from
so it's better to use the map navigation to get there quickly
And more accurate
In April 1975, after the holwg working group was set up, a series of documents on strawman language requirements were developed to plan the requirements of DoD high-level languages. In August, it was updated to Woodenman version; It was updated to Tinman edition in January 1976 and Ironman edition in January 1977. Finally, a series of documents on Steelman language requirements were formulated in June 1978. During this period, the working group concted a formal review of many programming languages and found that none of the existing languages could meet the document specifications. The working group has also offered four contractors, namely, red (Benjamin brosgol et al.), green (Jean ichbiah et al.), blue (John goodenough et al.), and yellow (Jay spitzen et al.), for suggestions on the development of new programming languages. In April 1978, the proposals of red group and green group were passed and advanced by the public. In May 1979, the green group proposal led by Jean ichbiah was adopted and named ADA in memory of ADA Lovelace, the founder of computer program. In June 1979, the preliminary design reference manual of Ada language was published by ACM in SIGPLAN notices. In October 1979, ADA held a public testing and evaluation conference in Boston; The Stoneman version was released in February 1980 in response to the revised requirements specification after the meeting. In July 1980, the revised version of ADA was completed; The military standards reference manual was approved in December and was awarded ADA Lovelace the number of year of birth 1815, named MIL-STD 1815. In July 1982, another revised version of ADA's reference manual was released. In 1983, American National Standards Institute (ANSI) standardized Ada language, and Gerhard goos and Julis Hartmanis explained the final version. In April 1983, New York University used the ADA / ed compiler of high-level setl to perform Ada language verification for the first time. Since 1991, the U.S. Department of defense has required all software to use ADA. In 1997, the rule was withdrawn
Augusta ADA king, the daughter of Byron, a 19th century poet, is a mathematician. The concept of loop and subroutine was established by the founder of piercer program. The first "program design flow chart" written for "algorithm" of calculation program is cherished as "the first person to write program for computer"
born in London in 1815, he lived with his mother five weeks after his birth e to the breakdown of his parents' marriage. His mother, a. millbanke, is an amateur mathematician. Instead of inheriting her father's romantic passion, ADA inherited her mother's mathematical talent
ADA married count William Lovelace at the age of 19, so history books also call her lady Lovelace. ADA's life is short. She foresaw the computer for a whole century. ADA died early, at the age of 36, similar to her father Byron. According to her will, she was buried next to her father in Nottingham
ADA designed a program to solve Bernoulli equation on Babbage analyzer, and proved that Babbage analyzer of 19th century computer maniac could be used to solve many problems. She even developed the concepts of loops and subroutines. Because of her pioneering work in programming, ADA Lovelace is known as the first programmer in the world. At that time, ADA, even though she was the mother of three children, firmly devoted herself to the research of analytical machine and became Babbage's partner. In a paper published in 1843, ADA thought that machines might be used in the future to create complex music, graphics and scientific research, which was a very bold prediction at that time. From the present point of view, ADA first worked out the "algorithm" for calculation, and then wrote a "programming flow chart". This precious plan is regarded as "the first computer program". Because Babbage could hardly speak in his later years e to throat disease, the text of introcing the analyzer was mainly completed by ADA for him
the US Department of defense is said to have spent 10 years mixing all the functions of the required software into one computer language, hoping that it will become the standard for thousands of military computers. In 1981, the language was officially named Ada (ADA) language in memory of the "world's first software engineer".
