Having to compare results on experiments or lab tests to each other.
Answer:
Data acquisition should follow a detailed collection plan that is set in advance.
Explanation:
The process of collection of data over computer with the help of electronic sensors is called data acquisition. The can be related to voltage, current, temperature etc.
For example
Data collection with the help of sensors to monitor weather conditions is an example of data acquisition. In this process data has been gathered on already planned format. Each column or row of data will be helpful to predict the weather condition such as, rain predictions, earthquake prediction etc.
That's why to collect this type of data, collection plan should be set in advance to gather relevant information with the help of data.
Answer:
The C++ code is given below with appropriate comments
Explanation:
//Remove this header file if not using visual studio.
#include "stdafx.h"
//Include the required header files.
#include <iostream>
//Use for maths function.
#include <cmath>
using namespace std;
//Define main function
int main()
{
// Define the variables
double targetValue = 0.3333;
double sensorReading = 0.0;
//Perform the opeartion.
sensorReading = 1.0 / 3.0;
// Get the absolute floating point value and
// Check up to 4 digits.
if (fabs(sensorReading - targetValue) < 1E-4)
{
//Print equal if the values are close enough.
cout << "Equal" << endl;
}
else
{
//Print not equal if the values are not
//close enough.
cout << "Not equal" << endl;
}
system("pause");
//Return the value 0.
return 0;
}
