Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")

Answer:
have the same SSID but different channels
Explanation:
Based on the information provided within the question it can be said that the best option to accomplish this would be to have the same SSID but different channels. This would maintain the users connected to the same network name (SSID) but still be able to roam and jump from one access point to the other.
Class Item {
// item class attributes
string itemName;
int itemQuantity;
double itemPrice;
...
}
class grocerylist {
// you can use arrays or any other containers like ArrayList, Vectors,...etc depends on programming language you use
Item[50] itemList;
int size;
public grocerylist () {
this.size = 0;
}
public void addItem(Item i) {
itemList[size] = i;
size = size +1; // Or size++
}
}
Answer:
no_of_shares = int(input("Enter the number of shares: "))
purchase_price = float(input("Enter the purchase price of the stock: "))
sale_price = float(input("Enter the sale price of the stock: "))
total_stock_price = purchase_price*no_of_shares
total_spend_on_buying = total_stock_price + (0.03*total_stock_price)
total_sale_price = sale_price*no_of_shares
commission_while_selling = total_sale_price*0.03
net_gain_or_loss = total_sale_price - (total_spend_on_buying + commission_while_selling)
if(net_gain_or_loss<0):
print("After the transaction, you lost {} dollars".format(abs(net_gain_or_loss)))
else:
print("After the transaction, you made {} dollars".format(abs(net_gain_or_loss)))
Answer:
boolean isEven = false;
if (x.length % 2 == 0)
isEven = true;
Comparable currentMax;
int currentMaxIndex;
for (int i = x.length - 1; i >= 1; i--)

for (int j = i - 1; j >= 0; j--)
{
if (((Comparable)currentMax).compareTo(x[j]) < 0)
{
currentMax = x[j];
currentMaxIndex = j;
}
}
x[currentMaxIndex] = x[i];
x[i] = currentMax;
}
Comparable a = null;
Comparable b = null;
