Using C++ Language
The following data points refers to three dimensional co-ordinates (x, y, and z axes,
respectively) in each line. The numbers are separated by a tab space. Save this data in an
input file named data.dat.

Define a structure with three integer members – one each for the x, y and z axis', and one
member of double data type – named distance.
Using a function, read the data in into an array of structures. Your program must be generic
and you cannot assume there are only 4 lines of data. You CANNOT open the file in this
function, it MUST be done in the main function.
In your main function, prompt the user to enter a three-dimensional point.

Define a structure with three integer members – one each for the x, y and z axis', and one

Using a function, read the data in into an array of structures. Your program must be generic
and you cannot assume there are only 4 lines of data. You CANNOT open the file in this
function, it MUST be done in the main function.
In your main function, prompt the user to enter a three-dimensional point.
In a separate function, determine which of the points in the file (now in the array) is closest
to the point entered by the user. This function must have the structure name as the
return type.
To do this, you need to evaluate the three-dimensional distance between each structure
point and the user entered point using the formula:
to the point entered by the user. This function must have the structure name as the
return type.
To do this, you need to evaluate the three-dimensional distance between each structure
point and the user entered point using the formula:
√(?1 −?2)2 +(?1 −?2)2 +(?1 −?2)2
and save the computed distance in the distance member variable.
You have to find the minimum of the computed distances and return the corresponding
structure.
In your main function, display the corresponding structure –the minimum distance as well
as the three-dimensional point.
and save the computed distance in the distance member variable.
You have to find the minimum of the computed distances and return the corresponding
structure.
In your main function, display the corresponding structure –the minimum distance as well
as the three-dimensional point.
