1. Key Building practices2. Design in software construction is a process of determining trade-offs and adjustment sequences, with tradeoff everywhere.3. The primary technical mission of the software is the complexity of managementDecomposition of the entire system into subsystems, subsystem high cohesion, low coupling, minimizing the complexity of a particular time period, thus reducing the mental burden4. Specific features of high-quality design:(1) Minimum complexity: simple, easy to understan

Exercise 3-3 the last three bits of the productEnter several words, enter a number of integers (which can be positive, negative, or 0), and output the last three bits of their product. These integers are mixed with a string of uppercase letters, and your program should ignore them. Tip: Try to enter a string when executing scanf ("%d").#include Summary: 1 Note overflow2 for a break in the bad, the next code is to determine where the for-through-bad exits from.3 sum = 0 Remember to clear the zero
