C/C++ :: Filling Array With Non Letter Char And It Outputs A Number?
Sep 2, 2014
I am trying to fill an array with blank spaces and instead i get the number 32 over and over, i think this is the ANSI code for that character. how do i get the character itself?
I need to count how many times letter appears in a text. I know that for default letters from 'a' to 'z' and from 'A' to 'Z' there is an interval. But I need also Lithuanian letters, such as ž,č,ę. I wrote this method: (it accepts char code and checks whether that char is a letter)
As you can see, a lot of checking in switch statement. I use 256 for this reason to have the same effect as unsigned char. But maybe there is a way to shrink down this method, or use some library?
#include <stdio.h> int main(void) { //2D Array int array[2][2]; int number = 1; }
[code]....
The array is not filled incorrectly for some reason, more specifically the first row.The first two cycles of the for loop seem to work correctly. One if the bugs seems to occur on the third. when array[0][2] is filled with number 7, for some reason array[1][0] changes it value to 7 as well.
In C how can I initialize a variable that is not a letter or number? For example with a number I can :
Code:
int i = 5; for ( i = 0; i <=5; i++ ); printf( "%d", i ) This would display a row of 5's
but what if I wanted to display a row of -----? What I am trying to do is read in a simple txt file, around the file I want ----1----2-----3 ect ect on the top ----a----b-----c down the side Then I want to be able to change the file at lets say position c2 and save it. This is the early stages of my attempt to set up a editable table.
Code: int arr2d[rows][columns] ; // Not valid syntax of course ... let be arr2d rows * columns size for(int i=0; i<rows; i++) for(int j=0; j<columns; j++) arr2d[rows][columns] = some_value;
What is the complexity? I believe O(n) and not O(n^2) on this case because if you have 3*3 size you would put 9 elements (from 9 elements input of course)... for each input you have one insertion and that is the meaning. Same as 4*4 size 16 input times 16 insertions .. or 5*5 and so forth...
For example if I have typed 0xFF (a literal hex number that represents the value 255 for Unsigned Char or -1 for Signed Char) in part of my program. That 0xFF is treated as a Char not an Int, because the value is within the range supported by Char, the C compiler always tries to use the smallest datatype possible for the number that is needed for a literal value like this.
Unfortunately because Signed Char is the default Char type, 0xFF is translated into -1. I am wanting to use it to represent 255. So I'm trying to tell the compiler that 0xFF should be interpreted as either an Int or an Unsigned Char. How do I do this?
I already tried typing it with the magic letter "I", like this: 0xFFI
But that didn't work. What is the correct way to do this?
I am working on Euler Project exercise number 17. Here is the problem from the website.
"If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.If all the numbers from 1 to 1000 (one thousand) inclusive were written out in words, how many letters would be used?"
So I have to write a program to calculate a grade letter into a number.
Letter grades are A, B, C, D, and F, possibly followed by + or –. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F–. A + increases the numeric value by 0.3, a – decreases it by 0.3. If the letter grade is illegal (such as "Z"), then your output should be "INVALID LETTER GRADE"; If the combination is illegal (such as "A+" or "F-") then your output should be "INVALID GRADE COMBINATION"
Also the code should look like this Enter your letter grade: C+ Grade value is [2.3]
// Input cout << "Enter your letter grade: "; string s; cin >> s;
Dont know how to replace each letter as s number ... this is the question i was given ...
In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem:
SEND + MORE = MONEY
A solution to the puzzle is S = 9, R = 8, O = 0, M = 1, Y = 2, E = 5, N = 6, D = 7.
Write a program that finds a solution to the cryptarithmetic puzzle of the following:
TOO + TOO + TOO + TOO = GOOD
The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from 0 to 9 to each letter. For example, it might first try T=0,O=0,G=0,D=0, thenT=0,O=0, G = 0, D = 1, then T = 0, O = 0, G = 0, D = 2, etc., up to T = 9, O = 9, G = 9, D = 9. In the loop body, test that each variable is unique and that the equation is satisfied. Output the values for the letters that satisfy the equation.
I have a string - a whole sentence that I want to assign a number to each letter, space, comma and period etc. So all "A's" will have the same number, all "B's" will have another number etc. I don't want to use the ASCII numbers because they all need to be sequential and some of the punctuation isn't. I have put the string into a char array to separate each character out and was thinking about running it through a loop with if statements for each letter and assigning numbers there and then saving the numbers in the order they appear into a list as a string but I keep coming up with errors so I don't know how to do it or if there is a better way to accomplish what I'm trying to do.
I am currently working on writing a word search program. However, I am stuck on reading the used input into the 2-D array. The code I've posted below is only dealing with the user input (I'll work on the word search part once I know i am correctly reading in the user input). I know the coding is bad practice with the use of hexadecimal, and getchar() ect. But I am currently using a microblaze microprocessor and this is just the way microblaze can interpret the information. As for the infinite while loops...that can be changed just trying to figure out how.
My question is how could I change my code to correctly read in the user input into the 2-D array?
Code: #include "platform.h"#include "xparameters.h" #include <stdlib.h> #include <stdio.h> #define MAX 20 int main() { char grid[MAX][MAX], word[30]; int i, j, arr[2],num;
Just trying to fill a dynamically allocated array with values then I want to print out the values using pointer method:
#include <iostream> using namespace std; long * extend_arr(long int arr[], long int length, long int val) { long * array2 = new long [length + 1]; for (int J = 0; J < length; ++J) array2[J] = arr[J];
[Code] ....
When this runs, I get an array with random numbers in it. For example, just trying to print the first value in *Block gives me random numbers each time. What is wrong with this as to why it is not holding the right values?
The extend_arr works perfectly fine, because when I try to access the values in the array using indexes (arr[0], arr[1], etc) it shows the right output, but using pointers does not. How can I make it work?
the real char got 1000 digits this is just example how do i convert chars from numbers[4] to numbers[15] and save them as one number ? in this case i will get int x = 5444546546545643 as u can see char numbers as a example above
typedef client...I would like to have these fields filled with this function below and stored in an array... Basically Multiple users and this is my function for it, if I can get it to work proper -.- .... I don't get syntax errors but I do get warnings
Code:
void getct(client *cl, int *pclientCounter) { char input[buff]; char *pinput = NULL; int typef = 0; int lengthf = 0; }
int firstarray[12][7] = { }; double firstClass(int airplane, int seats, double price) {cout<<setw(60)<<"---------------------... cout<<setw(60)<<"You are in **first class** booking screen
[Code] .....
The thing is, The first 2 rows having 7 columns like this:
0000000 0000000
User gives an input of seats reserved, for example user inputs 3 seats, then the program should give output like:
1110000 0000000
I will not ask any specific seat but put assign seats randomly where available.. How to do it?
I'm expected to get a starting minimum input, and also an ending maximum output (for example: 21, and 25). From here, i have to give output using all the numbers (in a row) between the min and max numbers.
(for the same example: 21 22 23 24 25)
I assumed I would want to create an array using a variable, but i'm not sure of that either.
