COBOL language training eighth lesson,
Lecture content: Pro * Cobol mainly embeds the SQL statement in the COBOL language, connects to Oracle's databases, and each statement should add the flag like Exec SQL.
Cobol has no future, this is the fact that there is no proven, but the Japanese need this, it can work for them in one or two years, so I still have a meal.
The teacher said that the Japanese benzene must die, and they still have such an old language without discrete, and many Japanese companies are still can't accept with COBOL's object-oriented concept.
Yesterday I also went to the technology to interview the engineer. However, the answer is not good: (there is no lesson training for testing.
I asked the teacher now. The original teacher is now engaged in testing, and it is very old, and it is still a female teacher. The Aerospace Department 706. She taught me the theory of test, but she still did not systematically, gave me a question, calculated the side length of the given triangle and calculated the area of the triangle. He told me to write a program with a test perspective.
1 Judge whether the three edges are effective numbers
2 Judging whether the three edges can form a triangle
3 finally remember the area of the triangle
The teacher said that a software's 20% code implements software features, 80% to control the program, and hold all programs.
The teacher also joked that the 400 lines of the program can come out of BUG, and a HelloWorld program has three bugs.
Strive to this first. Go To eat
