Define the summary function, which takes as arguments a database (dict) and a dict of current stock prices. It returns a diction

ary (dict or defaultdict) whose keys are client names (str) whose associated values are 2-tuples: the first index is a dictionary (dict or defaultdict) whose keys are stock names (str) and values are the number of shares (int) the client owns. The second index is the amount of money (int) the portfolio is worth (the sum of the number of shares of each stock multiplied by its current price). Assume each client starts with no shares of any stocks, and if a client owns 0 shares of a stock, the stock should not appear in the client’s dictionary. Recall positive numbers are a purchase of the stock and negative numbers a sale of the stock. E.g., if db is the database above, calling summary(db, {'IBM':65, 'Intel':60, 'Dell':55, 'Apple':70}) would return

Which phrase is the best definition of sparklines in Excel 2016?
ddd [48]

Answer:

Option 2: a type of mini chart that users can insert into a worksheet

Explanation:

A graph or chart is used to show trends and changes in a dataset.

When we have to show trends or changes in MS Excel, there are a lot of options available. One of them is Sparklines. Sparklines are like mini charts that can be used to show data graphically.

Hence,

The correct answer is:

Answer:

Implementation of resistor.cpp

#include "resistor.h"

Ohms::Ohm()

{

// default constructor

voltage=0;

}

Ohms::Ohm( double x) // parameterised constructor

{

voltage = x; // voltage x set to the supply voltage in the private data field called voltage

}

Ohms:: setVoltage(double a)

{

voltage = a;// to set supply voltage in private data field called voltage

}

Ohms::setOneResistance( String s, double p)

{

cin>>p; //enter the resistance value

if(p<=0) // if resistance is less than or equals to 0

return false

else // if re

cin.getline(s);

}

Ohms::getVoltage()

{

return voltage; //return voltage of ckt

}

Ohms::getCurrent()

{

return current; //return current of ckt

}

Ohms:: getNode()

{

return resistors; //return resistors of ckt

}

Ohms::sumResist()

{

double tot_resist = accumulate(resistors.begin(),resistors.end(),0); //std::accumulate function for calculating sum //of vectors and following are the starting and ending points

return tot_resist;

}

Ohms::calcCurrent()

{

if(current <=0) // if current is less than or equal to 0

return false;

else   // if current is greater than 0

return true;

}

Ohms:: calcVoltageAcross()

{

if(voltage<=0) // if voltage is less than or equal to 0

return false;

else //if voltage greater than 0

return true;

}

Explanation:

in the case of main.cpp its simple just make a class object and remember to include resistors.cpp with it for which the second last picture describes the process precisely. (Hint: Use theunit test case functions in the main.cpp).

As you can see node is a structure consisting of member variables, followed by a class Ohms representing a DC circuit.

By looking at these pictures, it is needed to implement the main.cpp and resistor.cpp files. The user defined header file resistor.h already consists of all contents of Class Ohm, struct node. You don't need to modify it in anyway in such case.
