Answer:

By conducting interviews

Explanation:

The key to making decisions about database requirements lies in research. It is important to understand who needs the information and where to find it. The most common sources of information include interviews, and business forms. Through interviews, you will be able to learn how information passes through an organization, how this information is used, and what reports are generated.

The signal strength and SNR are two important values to record during the manual site survey process. Signal loss and propagation loss have different effects, and packet retries are more of an issue with dynamic rate selection.

Which of the following is not a valid variable name? 2 myInt 2. return 3. myInteger 4. total3

Reptile [31]

Answer:

Correct answer is option (2) that is "return".

Explanation:

In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.

Some example of valid variables name:

foo

BAZ

Bar

_foo42

foo_bar

Some example of invalid variables name:

$foo ($ not allowed)

while ( keywords )

2foo (started with digit)

my foo (spaces )

Python exercise grade 10

guapka [62]

earliest = ""

while True:

month = int(input("Enter a date (month): "))

day = int(input("Enter a date (date): "))

year = int(input("Enter a date (year): "))

if month == 0 and day == 0 and year == 0:

break

if month < 10:

month = "0"+str(month)

if day < 10:

day = "0"+str(day)

string_date = str(month)+"/"+str(day)+"/"+str(year)

print(string_date)

if earliest == "":

earliest = string_date

else:

year,month,day=int(year),int(month),int(day)

lst = list(map(int,earliest.split("/")))

if year < lst[2]:

earliest = string_date

elif year == lst[2] and month < lst[0]:

earliest = string_date

elif year == lst[2] and lst[0] == month and day < lst[1]:

earliest = string_date

print(earliest,"is the earliest date")

I wrote my code in python 3.8. Best of luck.

Write a program, named sortlist, that reads three to four integers from the command line arguments and returns the sorted list o

yawa3891 [41]

Answer:

In C++:

void sortlist(char nums[],int charlent){

int Myarr[charlent];

const char s[4] = " ";

char* tok;

tok = strtok(nums, s);

int i = 0;

while (tok != 0) {

int y = atoi(tok);

Myarr[i] = y;

tok = strtok(0, s);

i++;

}

int a;

for (int i = 0; i < charlent; ++i) {

for (int j = i + 1; j < charlent; ++j) {

if (Myarr[i] > Myarr[j]) {

a = Myarr[i];

Myarr[i] = Myarr[j];

Myarr[j] = a;

} } }

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }

}

Explanation:

This line defines the sortlist function. It receives chararray and its length as arguments

void sortlist(char nums[],int charlent){

This declares an array

int Myarr[len];

This declares a constant char s and also initializes it to space

const char s[4] = " ";

This declares a token as a char pointer

char* tok;

This line gets the first token from the char

tok = strtok(nums, s);

This initializes variable i to 0

int i = 0;

The following while loop passes converts each token to integer and then passes the tokens to the array

while (tok != 0) {

int y = atoi(tok); -> Convert token to integer

Myarr[i] = y; -> Pass token to array

tok = strtok(0, s); -> Read token

i++;

}

Next, is to sort the list.

int a;

This iterates through the list

for (int i = 0; i < charlent; ++i) {

This iterates through every other elements of the list

for (int j = i + 1; j < charlent; ++j) {

This condition checks if the current element is greater than next element

if (Myarr[i] > Myarr[j]) {

If true, swap both elements

a = Myarr[i];

Myarr[i] = Myarr[j];

Myarr[j] = a;

} } }

The following iteration prints the sorted array

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }

}
