Write a sed command that will display all lines of the birthday file that do not contain the string March. What was the sed comm

Dmitriy789 [7]

Answer:

sed '/march/{d;}' birthdays.txt > result .txt

Explanation:

sed syntax is basically:

<em>sed '/expression/{command;command;...;}' inputfile > outputfile</em>

First, for the expression part, we use /march/ to match all lines containing that string.
Then for the command part, we only use {d} command to delete every matching line found.
The third part contains the input file to process, I have named it birthdays.txt, but it could have been any other file needed.
Finally "> result .txt" makes the script output to be saved into a file named result.txt

let p = preco;

let desconto = estaComDesconto;

if(p > 100 && desconto == false){

return "Quero pechinchar";

}else{

return "Negócio fechado";

}

Explanation:

function pecoDesconto(preco, estaComDesconto) {

// Implemente a função ao lado, que recebe um preço//

let p = preco;

// variavel que indica desconco//

let desconto = estaComDesconto;

//Se o preço for maior que 100 e não estiver com desconto, a função deve retornar Quero pechinchar.//

if(p > 100 && desconto == false){

return "Quero pechinchar";

//Caso contrário, deve retornar Negócio fechado

}else{

Which of the following statements contains an error?

ASHA 777 [7]

I. is syntactically correct if genderString exists. if genderString, for example, is "Male", then char gender would be the character at index 0 (the first character), meaning 'M'.

II. is incorrect. It is using the comparison operator (==) instead of the assignment operator (=). It is also setting a boolean variable to a String value of 'F'. Boolean values cannot hold string values, and can only hold true & false.

III. is correct if ageString only contains numbers (presumably, it does, as it's called ageString). Integer.parseInt is a function that converts String values to integer values if the string values only contain numerical characters.

The answer in this case should be B. II only.

Group of answer choices

A. policy and procedure development

B. use case activity diagram testing

C. method design and coding

D. data conversion and user training

Answer:

C. method design and coding

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

Among the listed stages, there are two (2) most important stages which cannot be ignored in the creation of a software application are.

<em>Hence, even if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are method design and coding.</em>

I. Method design: this is the third step of the software development life cycle, it comes immediately after the analysis stage. This is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

II. Coding (development): this is the fourth step in the software development process and it involves the process of creating a source code which would enable the functionality of the software application.
