Question about arrays...
Author
Ok, I have this class assignment that asks us to use a function template called min to determine the smaller of two *arguements*. It then wants us to test the program using integer, character and floating point numbers.
I've created a program that tests this, but i'll be used 6 differant variables...
Let me show you what I mean.
Now to my question. Instead of having 3 seperate prompts for values, is it possible to to have only one prompt? Hope this helps.
Or am I missing something completely?
Thanks for the help and the time you took to read this. :)

You're missing something completely. I don't really understand your question but you can't have an array where each element is of different data types. You could :
#include <iostream>using namespace std ;template< class dataType >dataType min( dataType a, dataType b ) ;int main( ) { int intArray[2] ; char charArray[2] ; float float Array[2] ; // Prompt user for two ints. // Save user input in both elements of the int array. // Prompt user for two chars. // Save user input in both elements of the char array. // Prompt user for two floats. // Save user input in both elements of the float array. cin.get( ) ; return 0 ;}Quote:
cout <<"\n\n Input two float values: ";
cin << flo1 << flo2;
And the cin uses the '>>' operator not the other one.

Ha...yeah. I should of double checked that, Thank you!
I think Frunny answered what I was trying to say but let me rephrase if I can.
Instead of prompting 3 seperate times, I only want to prompt once for the input.
Is that possible?
Heh, you could always go:
However, I kind of doubt that that's what you were looking for.
int int1, int2;char char1, char2;float flo1, flo2;cout << "Input two integers, followed by two characters, followed by two floating point values:" << endl;cin >> int1 >> int2 >> char1 >> char2 >> flo1 >> flo2;// find mins and output resultsHowever, I kind of doubt that that's what you were looking for.
I think he might be looking for this?
template <typename T>void test_input(std::string string_name) { T x; T y; // input into x and y // invoke min() // report result}test_input<int>("integers");// similarly other types
you could do a statement like this
that would ask the data type, prompt you to imput 2 of that kind of data, run your function on it, print the result, print "PRESS ANY KEY TO CONTINUE" then once you press a key it closes
You will want to modify "the smaller float value is" to fit the other data type and some other stuff too but i hop you get what i mean

#include <iosteram>#include <string>using std::namespace;template < class T >T min( T value1, T value2 ){if( value1 < value2 )return value1;elsereturn value2;}int main(){ string reader = "" cout << "imput for:" cin >> reader; if(reader == "float") { float flo1; float flo2; cout <<"\n\n Input two float values: "; cin >> flo1 >> flo2; cout << "The smaller float value is: " << min( flo1, flo2 ); system("pause") return 0; } ... //do that with all of em then else cout << "invalid data type"; system("pause") return 0;};that would ask the data type, prompt you to imput 2 of that kind of data, run your function on it, print the result, print "PRESS ANY KEY TO CONTINUE" then once you press a key it closes
