ASCII in C ++ and Java

Rape is easy to hide, and obscenity is hard to prevent. Today, I am severely molated by ASCII code, but I may not be able to hide the mathematical relationship in the future, however, I believe that with this website, I have a good reference for the speed of code query. I always feel that I have been plagued by some strange problems recently and have encountered them in my actual work and study. Sometimes it is just a small problem. The root cause is that my previous deep-rooted ideas have not changed.
Next, I will use some ASCII comparisons in C ++ and Java to solve the problems that need to be paid attention when converting int to Char. By the way, I will list and analyze various web coding specifications I know, I hope to help you.
C ++ code
# Include <iostream>
Using namespace STD;
Int main (){

For (INT I = 0; I <300; I ++ ){
Char c = I;
Cout <I <"-" <C <"";
If (I % 10 = 0 ){
If (I! = 0 ){
Cout <Endl;
}
}
}
Cout <Endl;

Int EIG = 8;
Int eigs = '0' + 8;
Cout <"convert normal int to Char:" <(char) EIG <Endl;
Cout <"convert non-common int to Char:" <(char) eigs <Endl;

Char eigc = '8 ';
Char zeroc = '0 ';
Cout <"convert normal Char to int:" <(INT) eigc <Endl;
Cout <"convert normal Char to int:" <(INT) zeroc <Endl;
System ("pause ");
Return 0;
}

Java code:
Package com. j2-canvas;
Import java. util. Random;
Public class inttochar {
Public static void main (string [] ARGs ){
Random ran = new random ();

For (INT I = 0; I <200; I ++ ){
Char c = (char) I;
System. Out. Print (I + "-" + C + "");
If (I % 10 = 0 ){
If (I! = 0 ){
System. Out. println ();
}
}
}
System. Out. println ();

Int number = ran. nextint (10); // convert a common int to a char ::
Char x = (char) number;
System. Out. println (x); // garbled

Int number2 = '0' + ran. nextint (10); // convert non-common int to Char ::
Char X2 = (char) number2;
System. Out. println (X2); // No garbled characters

Char EIG = '0 ';
System. Out. println (INT) EIG );

}
}

The reason is that the ASCII code specification is 7 bits and the int value is 32 bits. In int + char, the int value has a higher priority, that is, the char automatically converts the ASCII value to the int value, so there are examples and scenarios like '0' + 8.
Next, let's take a look at common codes and their features:
An unfinished version will be added tomorrow !!!!!
