And&&It is left-combined, that is, it operates from left to right.
So once the expression on the left is false, the whole &; The value of the & expression is false, and the correct expression will not be processed.
This is also called &; & short circuit
The values of m, n, b, a, c and d are all 1, so a >;; B is false, m = a & gtB=0, so the expression n = c > on the right will not be processed. b,
So the value of n remains the same.
