C :: Read A Line From Screen / Takes ASCII Values From Entered Text And Edit It
May 10, 2013This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code:
#include <stdio.h>
int main(){
int maxsize;
printf("How long is your message?

C++ :: How To Convert Bytes To ASCII
Feb 7, 2014How can I convert bytes to ASCII?, I read wikipedia about UTF-8 and I understood a little bit about add or split bytes to change the value.
Now I have those bytes
0xC7 0xE6 0xC2 0x91 0x93 0x7B 0xCE 0x01
And I found a program (DCode) that convert to 64 bits little-endian, supposedly those bytes in ASCII is this.

C/C++ :: Enable User To Upload Image And Convert It Into ASCII Text Using SDL
Apr 29, 2015Using C . I have been tasked (for a University assignment) to create a program that will enable a user to upload an image and convert that image into ASCII text using SDL on a Linux system. I've managed to open a window, display an image (non-selected) and convert it into grayscale using
case SDLK_g:
for (int y = 0; y < image->h; y++) {
for (int x = 0; x < image->w; x++) {
Uint32 pixel = pixels[y * image->w + x];
Uint8 r = pixel >> 16 & 0xFF;
Uint8 g = pixel >> 8 & 0xFF;
Uint8 b = pixel & 0xFF;
Uint8 v = (0.212671*r)+(0.715160*g)+(0.072169*B)/>;
pixel = (0xFF << 24) | (v << 16) | (v << 8) | v;
pixels[y * image->w + x] = pixel;
I am absolutely clueless as to how I can get the user to upload an image to the program and then begin the image -> ASCII conversion. I've found seem to be written in C++ or C# to make the conversion I should be using the GetPixelColour command?
C :: Convert Characters From Array Into ASCII Integers - Incompatible Types Error

C/C++ :: Find Max Number Entered By User And Terminate When Negative Number Entered
Jul 15, 2014I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.

C++ :: Subtracting ASCII Hex Value In 64 Bit Hex Value
Mar 31, 2015I have some ascii characters in a char variable.ex - char buf[100]="ab*(z&";
So each of the char in that char array will have some hex value.ex- *'s hex value is '2a'.
And I have a long long int variable in which there is a 64 bit hex value.
ex- long long int k=0x0000888888888888;
Now i want to subtract the char buff's hex value in k. How to accomplish it.
That is 0x0000888888888888
- 0x000061622a287a26
= 0x000027265e600e62 (final result in a buffer or a long variable is okay)
Later i want to reverse the result as 26e006e56272.It should be stored in a variable such that i should be able to access each byte from it(ex- '72'(last 2 hex digits))

C/C++ :: Wrapping Alphabet Using ASCII
Jan 26, 2011I'm currently working on a project that utilitzes a Caesar Cipher. Basically, it reads input from a file and then, depending upon the input file, requires encrypting or decrypting. The cipher used to encrypt/decrypt simply adds/subtracts an integer from each character in the input file. All input is lowercase alphabetic characters (ASCII 97-122). My problem is trying to figure out how to wrap the ciphered characters, e.g., if the cipher require a shift of +5 and the character read was 'x', a shift of +5 to the right would produce 'c' (beginning with 'x' and counting up 5 letters: 'y', 'z', 'a', 'b', 'c').
I've written some crude and cumbersome loops that will work, but there has to be a better way. It is my understanding that it can be done using the modulus operation, %, but I cannot figure out how. I spent several hours trying to figure out the modulus approach, but no luck.
