Targeting algorithm analysis

Q: How likely is a design athlete to hit a target with a total of 10 rings and even a 10 ring to hit a 90 ring? Use the default Algorithm Implementation? Analysis: 1) What is the possible score range for each target? If the target has 10 rings, the score can be 1-10 when the target is hit. If the target is not hit, the score is divided into 0. Therefore, the range of each target score is 0-10, which may be 11 in total. 2) the number of possible and most direct calculation methods: Hit 10 targe

1. Order of C ++ function parameters in the stack-from right to left The following example is used to verify the order of C ++ function parameters in the stack: Void test (INT I1, int I2, int I3) { Printf ("I1 = % d, I2 = % d, I3 = % d/N", i1, I2, I3 ); } Int I = 0; Test (++ I, ++ I, ++ I ); The output result is: I1 = 3, I2 = 2,

example is: public class Test { public static void main(String[] args) { Integer i1 = 127; Integer i2 = 127; System.out.println(i1 == i2); Integer i3 = 128; Integer i4 = 128; System.out.println(i3 == i4); }} After running, The I1 = I2 result is true, I3 = I4 result is false?
