1. A machine purchased for $28,000 is depreciated at a rate of $4000 a year for seven years. Write and run a C++ program that computes and displays a depreciation table for seven years. The table should have the form

Year
Depreciation
End-of-Year Value
Accumulated Depreciation

1
4000
24000
4000

2
4000
20000
8000

3
4000
16000
12000

4
4000
12000
16000

5
4000
8000
20000

6
4000
4000
24000

7
4000
0
28000

adhruv92 First And Last Time: I did NOT do this to actually do you homework for you, the reason I actually did it was for a C++ refreshment in math, secondly I thought since no one else will actually help you, I can give you an idea of how it is done but this is NOT exactly the right code you are looking for... what you want is to implement loops such as if(P < 2000) { Interest = , Compounded= , Etc} else if (P > 2000) && (P < 6000) { BLAH BLAH BLAH } YES you will learn loops and c++ to finish your homework if you do need help post here but I will not continue the code any further unless you show that you understand it and can continue on your own with implementing the stuff you need it to do...

    F = (P * power);
    std::cout.precision(20);
    cout<<"The Final Amount Is: "<< F <<endl;
    Sleep(10000);
}

Release Note: instead of all the fancy math work you can do:
F = (P * (pow((1+ ((I/100)/N)), (N *Y)))); cuz the formula is that but for whatever reason I get the wrong result so I put fancy steps in the code to get the right output

//Numbers where the 3rd number is the sum of the last two numbers infront of it...
//Example 1,1,2,3,5,8,13,21

#include <stdio.h>
#include <windows.h>

int main ()
{

int num, t;
double num1, num2, ans;

num1 = 0;
num2 = 1;

printf("Enter the Amount Of Numbers You Want?\t");
scanf("%d", &num);

printf("1\t%.0f\n2\t%.0lf\n", num1, num2);

for(t = 0; t < (num - 2); ++t){

ans = (num1 + num2);

printf("%d\t%.0lf\n", t+3, ans);

num1 = num2;
num2 = ans;
}

Sleep(10000);
return 0;
}
