    Question Need help with simple data types

    I need help in writing a program wich outputs the size of all the simple data types along with the minimum and maximum values for each of these simple data types. Is there a way to do all of this in a short call statement in a program without writing every line to output the data?
    If not, do I have to call every simple data type?
    Please help. Thanks with any help or suggestions.

    I think you'll have to individually print each type, but you can save typing using a macro or template function -

    Code:
    #include <limits>
    #include <iostream>
    
    using namespace std;
    
    
    template <class T>
     void TypeOutput(T a)
    {
    	
    	cout << "Size : " <<sizeof(T) << " Min: " 
    		<< numeric_limits<T>::min() << " Max: " << 
    		numeric_limits<T>::max() << endl;
    }
    
    int main()
    {
    	unsigned short a;
    	short b;
    	unsigned c ;
    	int d ;
    	unsigned long e;
    	long f;
    
    
    	cout << "unsigned short: "; TypeOutput(a);
    	cout << "signed short: "; TypeOutput(b);
    	cout << "unsigned int: "; TypeOutput(c);
    	cout << "signed int: "; TypeOutput(d);
    	cout << "unsigned long: "; TypeOutput(e);
    	cout << "signed long: "; TypeOutput(f);
    	
                   //etc
    
    	return 0;
    }
