simple program of c++ to understand the use array

This is the source code for understand the simple function of array.
Here we have to calculate the average temperature of 7 days using array in c++.
#include<iostream.h>
#include<conio.h>
main()
{
      float temp[7],sum=0;
      int i=0;
      while(i<=6)
      {
                 cout<<"enter the temp. of day"<<i+1<<"?"<<endl;
                 cin>>temp[i];
                sum=sum+temp[i];
                i++;
                }
                cout<<"\nAverage temperature :"<<sum/7.0;
             
                getch();

what is data type in c++

Fundamental data types

When programming, we store the variables in our computer's memory, but the computer has to know what kind of data we want to store in them, since it is not going to occupy the same amount of memory to store a simple number than to store a single letter or a large number, and they are not going to be interpreted the same way.

The memory in our computers is organized in bytes. A byte is the minimum amount of memory that we can manage in C++. A byte can store a relatively small amount of data: one single character or a small integer (generally an integer between 0 and 255). In addition, the computer can manipulate more complex data types that come from grouping several bytes, such as long numbers or non-integer numbers.

What is a data type?

When we wish to store data in a C++ program, such as a whole number or a character, we have to tell the compiler which type of data we want to store. The data type will have characteristics such as the range of values that can be stored and the operations that can be performed on variables of that type

Next you have a summary of the basic fundamental data types in C++, as well as the range of values that can be represented with each one:

Name	Description	Size*	Range*
char	Character or small integer.	1byte	signed: -128 to 127 unsigned: 0 to 255
short int(short)	Short Integer.	2bytes	signed: -32768 to 32767 unsigned: 0 to 65535
int	Integer.	4bytes	signed: -2147483648 to 2147483647 unsigned: 0 to 4294967295
long int (long)	Long integer.	4bytes	signed: -2147483648 to 2147483647 unsigned: 0 to 4294967295
bool	Boolean value. It can take one of two values: true or false.	1byte	true or false
float	Floating point number.	4bytes	+/- 3.4e +/- 38 (~7 digits)
double	Double precision floating point number.	8bytes	+/- 1.7e +/- 308 (~15 digits)
long double	Long double precision floating point number.	8bytes	+/- 1.7e +/- 308 (~15 digits)
wchar_t	Wide character.	2 or 4 bytes	1 wide character
