Question 1:

Julli [10]

Answer:

Following are the code to the given question:

#include<iostream>//header file

#include<math.h>//header file

using namespace std;

int main()//main method

{

long long x, x1, y, y1;//defining long variable

int count=0,i,j;//defining integer variable

cout<<"Enter a range for x coordinates: "<<endl;//print message

cin>>x>>x1;//input x and x1 value

cout<<"Enter a range for y coordinates: "<<endl;//print message

cin>>y>>y1; //input y and y1 value

for(i = x; i <= -x1; i++)//use nested loop that tests each coordinates

{

for(j = y; j <= y1; j++)//use nested loop that tests each coordinates

{

if(((2*pow(i,2)) + abs(2*i*j) + pow(j,2)) == 10000)//use if that checks condition as per the given question

{

cout<<"There is a planet at "<<i<<", "<<j<<endl;// print coordinates

count++;//incrementing count variable value

}

cout<<"Total number of planets detected are: "<<count<<endl;//print count value

return 0;

}

Explanation:

In this code, inside the main method long "x, x1, y, and y1" and integer "count, i, and j" type variable is declared that uses a long variable to input value from the user-end.

In the next step, two nested loops have defined that test each coordinate and define if block that checks condition as per the given question and use i, j, and count variable to print value with the message.

I have been trying to work on this for a while now, and this is on excel

Answer:

=IF(INDEX(INDIRECT(C10), B10)=0,"",INDEX(INDIRECT(C10), B10))

=IF((INDEX((INDIRECT(Dept,TRUE)),Reason))="","",(INDEX((INDIRECT(Dept,TRUE)),Reason)))

Explanation:

Given

Your formula:.

=INDEX(INDIRECT("Dept"),Reason)

Dept column = C (C10)

Reason field = B (B10)

The issue with your formula is that you failed to include a statement to test the falsity of the first condition; in other words, if your if statement is not true, what else should the formula do.

The question says that

"Nest the function inside an IF function so that issues currently displaying as a 0 will display as a blank cell" this means that

if the INDEX() function returns 0, a blank should be displayed in H10 blank, instead.

So, the right formula both of these two. You can use any of them

1. =IF(INDEX(INDIRECT(C10), B10)=0,"",INDEX(INDIRECT(C10), B10))

2. =IF((INDEX((INDIRECT(Dept,TRUE)),Reason))="","",(INDEX((INDIRECT(Dept,TRUE)),Reason)))

The two does the same function; the only difference is that

(1) considers the cell itself while (2) considers the contents of the cell.

The analysis of both is that

They both use a nested indirect reference to check for the content of cells displaying 0.

The first if checks for the above mentioned; if yes, cell H10 is made to display a blank else it's original content is displayed.
