How can I tell if the water pump and hose need replaced due to overheating

What is your question?

I took my car on a 334 mile trip today in hot weather driving 80mph on interstate and when i ran my a.c. the temp gauge would go high but never over the line into red. So i would go back and forth with turning the a.c. on and off due to the gauge . it always went down when I turned off a.c.. I got 230 miles into trip and all of a sudden my temp gauge fastly went into red and the hot light came on it took me about 2 miles to stop safely and the car was smoking severly I thought the car was in fire under the hood. So I stopped and shit it off and opened hood immediately. Let it sit for about 45minutes after it cooled off I added water to radiator and started it... (The gauge was down in cool ) so it was safe to try and nothing leaked out when i filled radiator until I started it and then everything I put in leaked out with antifreeze... My question is... Is it the water pump or hose?
