I know I'm not supposed to use system("PAUSE"), but this is self-study.
I have an extra credit project where I'm supposed to calculate an approximate the user's age based on the current date and their birthday. My problem is that I am not getting the proper date and time. C++ keeps giving me some random date. I looked up c++ time format on the internet because this is extra credit and not in my book.
I am currently using dev C++ 4.9.9.2. Here is my current code :
// included libraries
#include <cstdlib>
#include <iostream>
#include <iomanip>
#include <time.h>
#define cls system("cls")
#define pauseOutput system("pause")
void printM(int x);
void age(int m, int d, int y, int &yearAge, int &monthAge, int &dayAge);

Write a C program with a separate function which calculates the sine function from the first principles according to the formula below. The code should find the sine value in 5 stages and then final answer
formula below :
sin(x) = x −x3/3!+x5/5!−x7/7!+x9/9!
I have done the code and it just gives me a final sine wave
it should find a error then plus one so on till it gets the answer

I have two numbers and a number that is final number. Which number is approximate the final number ?
For example:
Our final number is : -1/2 and the two numbers is 4 and 3. How can I compare it ?
Or i have numbers more than two like 5 number or 7 number or so foth numbers and final number is : -1/2

I was given an assignment for class to calculate the area of a circle using only the radius as a user input and not using Pi in the code. I need to do this by calculating the areas of a series of rectangles under the curve and adding them together.

My question is not in c++ programing , but because my aim is to make code that calculate the three angles between two vector i ask my question here
So as the title i have three point that create two vector and I want to get the angles in x,y and z of the point2
I used crosproduct that give me one angle without axe , I don't know in which axe this angle
My aim is the three angles for the 3 axes ....
Now I know there's a simple way to calculate highest value. But here i have this algorithm which i understood part of it.

calculate the factorial with function
The program should then calculate the factorial of the number n, where n!= n×(n −1)...× 2×1
the output like this:
Enter number: 4
Factorial of 4! = 24
Enter number: 6
Factorial of 6! = 720
Enter number: 3
Factorial of 3! = 6
Enter number: 0
Factorial of 0! = 1
Enter number: -5
Factorial of -5! = -1

How can we calculate tax of vehicle with polymorphism? There are 3 types of vehicles: long, commercial, and private vehicles' classes. There is a common class about all vehicles.
BASE class:
1.Brand and series name (such as Toyota Corrolla, Isuzu etc.)
2.Year of production (you can term it model)
3.Engine size in dm3
4.Owner’s name (including surname) and identity
5.Plate number.
COMMERCİAL :
1.Number of seats (apart from the driver)
2.Data to indicate whether the commercial vehicle is allowed to operate at night.
LONG :
1.The tonnage (max load in tons)
2.Data to indicate whether the long vehicle is allowed to carry goods internationally.
PRİVATE:
1.The class label which can be one of {A,B,C} .
I am trying to create a small function that can return the mean of an object of array class, not a simple array.
Declare and initiate the array:
array<double, 100> myArray = {};
myArray.fill(1.0);
function to calculate mean:
double mean_array(double *array)
{
double sum = 0.0;
for(int i=0; i<sizeof(array); i++)
sum += array[i];
return sum / sizeof(array);
}
However, it does not work. It seems it is incompatible with the array definition.

I AM HAVING TROUBLE CALCULATING THE PERCENTAGE. I HAVE TO CALCULATE THE AMOUNT OF MONEY FOR 6 YEARS.
I have a program that allows the user to enter a specific number of test scores. Based on these test scores, the program should display the average score and calculate how many of the scores were above 90. I have most of it done but I'm having trouble figuring out how to calculate the number of scores that were above 90. What am I doing wrong?
This is my code:

Question: Write a program that calculates sum of the numbers in the given positions.
Input specification : There will be 4 lines of data. You will be first given the size of the positions array (n). Then, the following line will have n integers which is an ordered list in increasing order and 0 < n ≤ 3000. The third line will give the size of the number array (m) where 0 < m ≤ 5000 and The last line will have m integers between -30000 and 30000.
Note: The positions start from 1 and goes until m.
Output specification : Show one integer number. Sum of the Numbers in the given Positions.
Sample Input I
