// This simple program shows the size and ability of primitive data types to handle minimum and maximum values, to take care about it, while you write a program.

#include <iostream>
#include <climits>
#include <cstdlib>

using namespace std;
int main()
{
   cout<<"Size of char = "<< sizeof(char)<<" bytes \n"
       <<"Minimum number of char data type = "<<CHAR_MIN<<" value \n"
       <<"Maximum number of char data type = "<<CHAR_MAX<<" Value \n"
       <<"Maximum number of unsigned char data type = "<<UCHAR_MAX<<" Value \n";

   cout<<"\nSize of short int = "<< sizeof(short int)<<" bytes \n"
       <<"Minimum number of short data type = "<<SHRT_MIN<<" value \n"
       <<"Maximum number of short data type = "<<SHRT_MAX<<" Value \n"
