I have only the USB cable so can I charge it with my laptop or computer or any other way?

You might get a small trickle-charge by connecting to a Windows laptop, better if you don't run the iPad whilst doing so, but only a Mac is capable of recognising & supplying the higher power requirement of an iPad.
Connected to any standard USB port on a PC, the device will claim it is not charging - though in practise it will eventually manage to charge it, it will be very slow.
Your best bet, if you don't own a Mac, is to buy a dedicated iPad charger.
The iPad uses a 10W charger. The iPhone has a 5W charger. Most older computers only support the original USB spec of 2.5W USB port power support. Your iPad, when on, uses more than 2.5W, so it will not charge unless it's turned off, and when off it will charge at less than 1/4 the speed of the normal iPad charger. That can be up to 16 hours for a fully depleted iPad.
Newer Apple computers, and computers that support USB3.0, support higher USB power standards, but if your computer doesn't then you'll need to invest in a new charger for your iPad.
Note that the iPad will generally charge off other USB chargers from other manufacturers, but only at a slower rate than the original iPad charger, unless the charger you use is specified to charge the iPad. When the original iPad came out 10W USB chargers were not common.
Charging more slowly won't make any difference, other than reducing the slight side effect of heat buildup on the iPad.
But it's perfectly OK to use lower powered ports such as those on your computer instead of the main powered chargers.
It's also perfectly OK to do it the other way around; you can charge your iPhone using the more powerful 20W iPad main adapter. It won't actually charge any faster than using the equivalent iPhone adapter, though. People will warn you that you'll damage your iPhone using this method, but that's simply a misunderstanding. 20W is the amount that the charger is capable of delivering, but if the phone doesn't ask for it, it doesn't get it. It's not all or nothing.
