C++ integer division by zero
WebOct 8, 2010 · I.e. in your assembly-language experiment you are dividing +32768 by -1. And the result is -32768, as it should be. Nothing unusual here. If you want to represent -32768 in the DX:AX pair, you have to sign-extend it, i.e. you have to fill DX with all-one bit pattern, instead of zeros. WebThis program demonstrate how exception are handled in C++. This program performs division operation. Two numbers are entered by user for division operation. If the dividend is zero, then division by zero will cause exception which is thrown into catch block. If the answer is less than 0, then exception “Division is less than 1” is thrown.
