The second question==y (z=4) what do you mean

CodePudding user response:

Since have braces, that operation optimization level is obvious, the z first assignment is 4, and then judge y==z, and y=0, z=4, the two are not equal, so the right value becomes zero, the operation is * x=0; The result is 0, if the value of y, and z assignment is the same, the right value is 1
