Channel and Coding Some Experimental Questions Written in C Language Seek masters

Embedded software generally needs to focus on three aspects: performance, security, and development efficiency (including portability, etc.).

In terms of performance (operational efficiency), the compilation is clearly the highest. But assembly is clearly the lowest in terms of security and development efficiency (not considering machine language - so unless it's an embedded platform that requires extreme performance (or the system is too simple to support high-level languages, orz- not many people use assembly language).

Other high-level languages are generally less efficient than C (C programs can run up to 80% of assembly efficiency, while other programs may only run 80% of C programs), and the source and target may be longer. For embedded systems, the bottleneck of performance is very fatal, and it is likely that a program written in C will achieve the desired goal, while a program written in another language using the same algorithm will not. (For this reason, however, there aren't many programming languages available for implementation on embedded systems.)

Depending on the purpose of the system, the security design of embedded systems is also a part that must be considered (e.g. for use in healthcare facilities) and potential errors must be minimized as much as possible during development. C is not dominant in this regard, but it is acceptable if it is guaranteed that ** strictly adheres to safety norms (comparatively, the compilation is depressing--

Development efficiency and security are similar, and within acceptable limits.

I'm your teacher, I'm so disappointed by you, you guys are waiting for the next semester to make up for the exam!!

The difference between the upper and lower case ASCII codes is 26, and it is good to judge the numbers.

1.Communication Engineering.

Communication engineering is a broad major. The main rounds of morning hall learning: circuit, signal and analysis, electronic technology, the principle of communication system, digital communication system, communication network basics, telecommunication network, program-controlled switching technology, wireless communication technology, digital microwave Layin communication, etc.

After graduation, students will be able to engage in research, design, manufacturing, and operation in the field of communications. Most of them are engaged in the development and application of advanced engineering technology and equipment in various sectors of the national economy and the national defense industry.

Knowledge and Abilities Required:

1. Master light wave, wireless, multi-** and other communication technologies.

2. Analyze, design, and debug international communication systems and communication networks.

This ** is relatively large, and I will take a position first.

This can't be written in two lines.,Go to Google....

There are a lot of implementations here!

delta g(t) = 2 * pi * g * ri+1 - ri + sqrt(ri*ri + h*h) -sqrt(ri+1 * ri+1 + h*h) )

Is it to be concretized?

#include #include using namespace std; int main() int a,b;a is the output result, b is the temporary input data char x; x is the punctuation type, cin>>a; Enter the first number while(1) Since you don't know how long the operation is, you use an endless loop to keep reading { cin>>x; Enter the operator if(x.

Add four to each character.

Wrote a ** and tested it,"0101011010"This string can't be decoded correctly, is there a mistake in the stem? #include ""
