Write an ASCII character display program

stack segment para stack 'stack'

db 512 dup(?)

stack ends

code segment

assume cs:code,ds:code,ss:stackstart: mov dl,10h ;The DL is initialized to 10 hours, and the initial value of the ASCII code is stored.

mov ch,000fh line cycle count 15 ; Here's a row loop.

next1: mov cl,0010h

Number of column cycles: 16; Here's the column loop.

Next: Call Display displays the characters within DX.

inc dl ;DL self-incrementing.

call blank ;Space.

dec cl ;Columns are self-subtracting.

cmp cl,0 ;End of judgment column?

jne next ;Not over, continue.

call enter ;The column ends with a carriage return wrap.

dec ch line self-subtraction.

cmp ch,0 ;Judgment line ends?

jne next1 ;Unfinished, next line.

mov ah,4ch ;End the program.

int 21h

display proc ;Display character process.

mov ah,02h

int 21h

ret display endp

blank proc ；Displays the space process.

push dx

mov dl,20h

call display

pop dx

ret blank endp

enter proc ;Enter the wrapping process.

push dx

mov dl,0dh

call display

mov dl,0ah

call display

pop dx

ret enter endp

code ends

end start

This can be done with C++.

**As follows: include

using namespace std;

int main()

char a;

int i;

cout<<"Please enter a character:";

cin>>a;

i=a;cout

Write a program in C language, and then output ASCII code You can output the characters in the form of integers as the output ASCII code, and the specific programming ideas and methods are as follows:

1.First, define a variable A as the variable that needs to output ASCII codes, and use the character variable A as an example.

2.Then use the scanf() function to accept the characters entered from the keyboard.

3.The character A is then output as an integer using the printf() statement.

4.Finally, run the program, and you can see the characters output in ASCII code format in the program's debug window.

1. First of all, open C++ and define two character variables z and z to save the converted characters.

2. Next, define an integer variable n and save the ASCII code for conversion.

3. Assign the value of n to the variable z to realize the conversion of characters.

4. In the output window, output the characters to which the ASCII code is converted.

5. Reassign the value of variable n, and its value is the ASCII code of the capital letters.

The output control string of the printf function is used to easily output the ASCII value of the character variable. Let m be a char-type variable that has been assigned, then.

printf("%d",m);Decimal ASCII value of the output variable m;

printf("%x",m);Hexadecimal ASCII value of the output variable m.

For example: char y='x';

printf("%c ",y);Get the character x

printf("%d ",y);Get the baiascii code of the character variable, decimal number.

printf("%x ",y);Get the ASCII code of the character variable, hexadecimal number.

printf("%o ",y);Get the ASCII code of the character variable, octal number.

You can also define the character ch first, enter the character, and then forcibly convert the character to an integer, which is the ASCII code value of the character, that is, int(ch).

Just output the characters in integer format.

For example: char c ='a';

printf("%d",c);

It's okay to assign values to each other, as long as the number of integers doesn't exceed the range of values for character variables.

Use the output of the printf function to control the bai

The control system of the string can be easily input to the ASCII value of the character variable. Let m be the char-type variable of the assigned version, weight.

Then printf("%d",m);Decimal ASCII value of the output variable m;

printf("%x",m);Hexadecimal ASCII value of the output variable m.

%d,%x。Characters and shapes, such as the number 0, ASCII is 0x30 = 48The essence makes no difference.

It can be assigned to an int variable to output directly, and an integer variable can be assigned to a character variable that overflows if it exceeds 255.
