Program that receives the current temperature as input. If the temperature is 80 degrees or more, output a message telling the user to go swimming, otherwise, if the temperature is 50 degrees or more, output a message to go running, otherwise stay inside.

#include <iostream.h>

void main()

{

double temperature;

cout<<”Input Temperature :”;

cin>>temperature;

if (temperature<=80)

{cout<<”go swimming”;}

else if (temperature<=50)

{cout<<”go running”;}

else

{cout<<”stay inside”;}

}

The system accepts maximum 2 input of answers for a displayed mathematical question. “WELL DONE” message is displayed for the correct answer and “TRY AGAIN” for the wrong answer. “SORRY. TIME’S UP” message is displayed if both answers are incorrect.
