How software engineer different from other engineers

One day, a Mechanical Engineer, an Electrical Engineer, a Chemical Engineer and a Software Engineer were driving down the street in the same car.

The car broke down.

The Mechanical Engineer said, "I think a rod broke. We can check the rods."

The Chemical Engineer said, "The way it sputtered at the end, I don't think it's getting gas. We shall check the gas tank."

The Electrical Engineer said, "I think there was a spark and something is wrong with the electrical system. We shall check the circuitry."

All three turned to the computer engineer and said, "What do you think?"
