int temp;

//Prompt user for input

cout<<"Enter temperature (in Celcius) : ";

//Check if input is acceptable

while (! (cin>>temp)) {

cout << "That was invalid. Enter a valid digit: "<
cin. clear (); / / reset the failed input

cin. ignore (123,'/n'); //Discard previous input

}

//Check if temp is greater than 40

if (temp>40) {

cout<<"It's extremely hot day today!";

}
