Financial goals are helpful because they

1 answer:

They help you establish a stable future. If you want to pay off a credit card debt, for example, you may make sensible choices such as paying more than the minimum due each month. A smart way to achieve this is to set a goal to pay off your debt within a certain time frame. You can calculate exactly how much you have to pay per month in order to achieve your goal. Without this plan, you could be in debt much longer than you need to be and pay much more in interest charges as you continue to carry the debt. In addition, more time in debt means more chances for unexpected financial circumstances in which you cannot make payments and risk default. @sapling Hope this helps, and if your feeling generous feel free to leave a rate, thanks (and maybe a brainliest? it would really help me get virtuoso I would appreciate it) ;)

Date Time Manipulation Exploration If you start from Jan 1st, 1757, and repeatedly add 8 days, until you hit 1800, how many time

zimovet [89]

Answer:

from datetime import datetime, date, timedelta

def count_weekdays(start_date, add_days, stop_year, weekday):

my_date = start_date

m = 0

while my_date.year != stop_year:

my_date = my_date + timedelta(days = add_days)

if my_date.isoweekday() == weekday:

m += 1

return m

date_val = date(1757,1,1)

try:

date_val = datetime.fromisoformat(input("Enter date in the format yyyy-mm-dd: "))

except ValueError:

print("Wrong isoformat string")

print(count_weekdays(date_val, 8, 1800, 1))

Explanation:

The datetime package of the python programming language has several time modules like the date, datetime, pytz, timedelta, etc, used to manipulate date and time in documents. The function count_weekdays has four parameters and returns the number of a specified weekday in a period of time.

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation

weqwewe [10]

Answer:

speed and storage

Explanation:

The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.

Array Implementation:

Pros: Much Faster and Easier to target a specific element
Cons: Much More Space needed

Linked Implementation

Pros: Less overall space needed
Cons: Much slower speed.

Convert the following C program to C++.

ki77a [65]

Answer:

The program equivalent in C++ is:

#include <cstdio>

#include <cstdlib>

#define SIZE 5

using namespace std;

int main(int argc, char *argv[]) {

int numerator = 25;

int denominator = 10;

FILE * inPut = fopen(argv[1], "r");

FILE * outPut = fopen(argv[2], "w");

float result = (float)numerator/denominator;

fprintf(outPut,"Result is %.2f\n", result);

float arr[SIZE];

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

fscanf(inPut, "%f", &arr[i]);

fprintf(outPut, "%7.4f\n", arr[i]);

}

return 0;

}
