character

问题 I've just started learning how to program in C and I'm trying to make a program that accepts a number and uses it as an ASCII value to return the ASCII character associated with that value. The program works when the parameters are predefined but when I introduce the scanf function it compiles but doesnt give me the same results. Here is my code : #include <stdio.h> int main(void) { question2(); return 0; } int question2(void) { int myInt = 65; scanf("%d", myInt); char ch = myInt; printf("%c"

问题 Say I have a number 0 that corresponds to the ASCII character a . How would I go about converting a number in the range 0 to 25 to letters in the alphabet? I have already tried adding 97 to the decimal value, but it just outputs the number+ 97 . typedef enum { a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z } set; void dispSet(set numbers[], int size_numbers) { int i; printf("[ "); for (i = 0; i < size_numbers-1; i++) { printf("%d, ", ((char) numbers[i])+97); }

问题 I created xAxis to show my characters in the center of the screen because I'm creating Puzzle Word project, now my issue is my characters showing from left, how to convert from left to right ?? because my characters are Arabic. For example my word is (London) but show me inversion (nodnoL) This example is in English. So how to fix this issue convert to right side or left side ?? This my code : for (indexTar, tar) in data.ans.characters.enumerated() { let x : CGFloat = (width / 2) -

问题 If I have a string "ja.v_,a" , how can I remove all non-letter characters to output "java" ? I have tried str = str.replaceAll("\\W", "" ) , but to no avail. 回答1: Could you try this one? System.out.println("ja.v_,a".replaceAll("[^a-zA-Z]", "")) //java 回答2: I would like to refer to this article and quote it: Regex examples and tutorials always give you the [a-zA-Z0-9]+ regex to "validate alphanumeric input". It is built-in in many validation frameworks. And it is so utterly wrong. This is a

问题 I'm trying to break down an integer with C on an 8-bit microcontroller (a PIC) into its ASCII equivalent characters. For example: convert 982 to '9','8','2' Everything I've come up with so far seems pretty brute force. This is the main idea of what I'm basically doing right now: if( (10 <= n) && (n < 100) ) { // isolate and update the first order of magnitude digit_0 = (n % 10); // isolate and update the second order of magnitude switch( n - (n % 10) ) { case 0: digit_1 = 0; break; case 10:

问题 I programmed a lot in java and know the basics of python and sometimes I play with c++... And those are all High Level Programming Languages and they're great and all but I was curious about how things worked at a deeper level in this case assembly language... I started to learn assembly for the x86 processor and chose NASM as my assembler. I spent some time learning how registers and the stack work, how the information is stored and how the information can be changed , not just reading but
