I'm trying to write a lot of sample code to practice but I can not figure out how to take a string and sort each character in order of their increasing ASCII codes. I'm getting stuck trying to separate each letter to determine it's ASCII code. I know I have to use an array somehow, So far, this is my code:
#include <stdio.h>
#include <stdlib.h>
#define _CRT_SECURE_NO_WARNINGS
[Code].....
I am looking for a way to sort a string just by the alpha characters, not by the ASCII table. Therefore
string sort(string name) {
sort(name.begin(), name.end());
return name;
}
will not work. And I am looking for the most simple way to go about it!
I have a C program where I rapprendentare a table using a 10x10 matrix and create the chart with the game piece and the matrix in a spiral. I do not know how to start or even how to create the table with the ascii codes. is a task for school and I need to do it soon.

here is what it does;it reads from a text file and converts the characters to ascii numbers and stores them in 1D array.what I am trying to is storing these ascii codes in 2D array.
I am trying to store the HTML codes for different characters in an array, but I am not sure how to do this, so that when using the keybd_event it can be plugged in.
If you try to do it with a string for storing the HTML code, you get this error.
string HTML[1];
HTML[0] = "A"; //A
keybd_event(HTML[0], 0, 0, 0);
I could do it in a very long if/else statement, but this would be much easier to call and get data from, and take up less space.
#include<iostream>
#include<conio.h>
using namespace std;
int main(void){
clrscr();

I am trying to print ascii characters but problem is If i put a limit in for loop to 255 or more than 126 the output don't stop it keeps on going
I know there is another way to this program but what i want to know this why this happen in this logic....it doesn't happen if a<=125 or less then 125.

My issue is now a segmentation fault in my sorting algorithm. In my assignment I was suppose to implement quick and insertion sort for the file, and organised strictly by ASCII values. We were allowed to look up generic algorithms for the sorts, but we have to convert them to comparing char arrays.
I haven't started trying to configure quick sort yet, but I'll supply the generic algorithm as well. keep in mind that the first line in the file contains the number of lines in the file. I'll try not to disappear this time!

What shall I learn in order to send values from 0.00 to 5.00? I'm working with they Hitachi 16x2 LCD display.I've been sending/displaying literal values on it all day.
Code:
SendCharater(unsigned char val)
where the variable val corresponds to the LCD character table.I can also send Hello World to the display, like so:
Code:
void putsXLCD(unsigned char *buffer){
while(*buffer) // Write data to LCD up to null
{
while( BusyXLCD() ); // Wait while LCD is busy
SendCharacter(*buffer); // Write character to LCD
buffer++; // Increment buffer
}
return;
}
I could type in putsXLCD("5.00") in order to display it on the LCD, but how do I implement this automatically for values, e.g. 0.00 to 5.00?It appears I can only pass literal values through the function SendCharacter, meaning that in order to display "0" I have to pass the value 0x30 (the hex value of "0" on the LCD Table).
My current thought process:Much like passing "Hello World" in the function putsXLCD(), I need to assign a pointer that points at each value in the "array" that I need to send. E.g., I need to send 3.24, so I need to point to "3", fetch the corresponding hex value in the LCD table, in this case 0x34, and the pass this 0x34 into the SendCharacter function, and so on. So, if this is the case, how can I fetch the corresponding hex value?
I'm writing a program that reads and counts all the printable characters (ASCII 32-126)found in a text file.
For example if the text file read: Why so serious?
The output to the screen would display(in order of ascii value however):
Character-----Total
W--------------1
h--------------1
y--------------1
s--------------3
o--------------2
etc...
However, I don't think it's reading any of the characters.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cmath>
#include <string>
using namespace std;
int main() {
int i, count[127];

Write a program that reads alphanumeric characters from the keyboard, and computes the average ascii value of the alpha numeric characters, the average alphabetical character, the average numeric character and the average uppercase character. Outputting each, you program should terminate reading once it read a non-alphanumeric character.
Here's what i have so far.
Code:
#include <stdio.h>
#include <ctype.h>
int main(void) {
int value = 'a';
int digit_loop = 0;
int alpha_loop = 0;
int upper_loop = 0;

The code is supposed to convert characters from an array into their respective ascii integers, and append a 0 if the number is less than 3 digits long. It then supposed to put it all together into one string.
Code:
#include <stdio.h>

#include <stdlib.h>
int main(void){
char file[] = "This is a test";
char *ptr = file;
int length = strlen(file);
int i, numbers[length];

My program reads a string of characters. Prints all occurrences of letters and numbers, sorted in alphabetical and numerical order. Letters will be converted to uppercase.Other characters are filtered out, while number of white spaces are counted.
the problem is it crushes when i run the program
Here is my code
#include <iostream>
const int SIZE = 100;
using namespace std;
int main() {
char *pStr, str[SIZE] = "", newStr[SIZE] = "", ch;
int count = 0, i = 0, j;

Now i am utilizing vectors in my codes.If i want to make a vector and i use #define to put a limit on the amount of variables it can contain. Until now i can do that. But let's suppose that i put 40 variables as its max capacity, but an user just needs to use only 12 or 14 variables. Put a rule that if someone has finished inserting his data and he is yet to fill the whole capacity of the vector the code.As to say : "If case you want to end press 0" .Edited : My computer has windows 7 and i took Codeblocks as my editor.
View 2 Replies View RelatedI have a program that I made, which does a list of stuff, then checks if a key is pressed, and if it's pressed, stop the looping.
The problem is, it checks if the key is pressed once a loop, which means that if the list has delays, you have to hold the button down for a while (depending on the list).
Here's an example:
Move mouse;
Pause program for 2 seconds;
Move mouse;
Pause program for 2 seconds;
Check if key is pressed;
What ways can I fix this problem?

so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?

Im supposed to find the common characters between two string characters, assuming that the user wont input duplicate letters like ddog. When I run my code I get an output of a question mark upside down. Here is my code with comments on what each part is supposed to do

I have an array of characters. I am trying to find "houston". The only way I can think of to do this is to use a for loop and check each individual character. Is there an easier way to do this?

How do I print this without generating errors?

I 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))
I know how to find find ASCII value of given character, but I am not getting how to find ASCII value of given string. For example I want to find ASCII value of string "HELLO",so how to do that.
