C :: Turning String Of Numbers Into Array Of Individual Integers

Mar 2, 2014

In my program, I am fed a string that contains integers such as Code: *str = "45678" and my program is simply supposed to read the number in and store each given number in a separate spot in an integer array. So basically, when my program has finished running it should be stored like:

Code:

arr[0] = 4
arr[1] = 5
arr[2] = 6
arr[3] = 7
arr[4] = 8

The way I have been attempting to do this was just copying it to the array like so:

Code:

arr = malloc(sizeof(int) *(strlen(str));
for (i=0; i<strlen(str); i++) {
a->digits[i] = str[i];
}

however, this just seems to return an impossibly high garbage value when I do. I'm assuming the way I'm trying to store it is 'illegal', but I cant seem to find online a proper way to do it.

C :: How To Take String Of Numbers And Turn It Into Array Of Integers

Mar 2, 2014

I know strings are essentially just arrays of characters, so what would be the easiest way to take each individual digit and put it into a separate space in an array?

ex.) *str = "90210"

array[0] = 9
array[1] = 0
array[2] = 2
array[3] = 1
array[4] = 0

All my attempts at achieving this just result in an array full of garbage numbers. What I've done is

Code:
int *array;
array = malloc(sizeof(int)*(strlen(str));
for(i=0; i<strlen(str); i++) {
array[i] = str[i]
}

also, I should mention that the string will be defined in main, and its converted into an array in a separate function.

C :: Replacing Individual Chars In A String Array?

Nov 16, 2013

I'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:

Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word
int CompareLetter(char array[], char guess, int numLetters)
{
int i;

[Code....

However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.

C/C++ :: Reading In A String And Turning It To Int

Dec 10, 2014

I have a problem with transforming a string, for example

"13 + 19"

and store this in a list as seperate integers,

list = {13, 19};

and another list with the +, -, /:

list2 = {+};

this is my function:

int evaluate(char* formula, int* result) {
struct List *listofintegers = list_create(); //creates a list, this is the structure:
/*
struct ListNode {
int value;
struct ListNode* next;

[Code] ....

This is how i execute my function in my main.c:

int value;
evaluate("19 + 16", value);

This is what i get in my prompt:

I will also have to seperate the +, - and / in another list,

I don't even know how i can get my string when char* formula is given as an argument...

C++ :: Eliminate Comma And Split String Into Individual String Variables

Nov 15, 2013

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);

[Code] ....

Output of the code is
3 J JD
k

but I want
3
J
JD
K

Also after I split the string is there any way to put the split string into individual string variables.

C :: Take Integer And Splits It Into Individual Numbers

Oct 9, 2013

I'm supposed to write a code that takes an integer and splits it into individual numbers e.g. 234 becomes 2 3 4 .the individual numbers are then passed on to a function that accepts only one number at a time

All i could think of was this,but its a very bad method coz i dont know how long a number would be inputed into "Angle_in_degree"

Code:
int Angle_in_degree,a,b,c
c= Angle_in_degree %10;
b=Angle_in_degree/10 %10;
a=Angle_in_degree/100 % 10;

function(a);
function(b);
function(c);

C++ :: From Array Of Integers Take Numbers That Occur Only Once

Jan 14, 2013

I am trying to find a way to do something like this:

input: 3 4 7 4 3 3 7
output: 3 4 7

So what I am trying to do is from an array of integers to take numbers that occur only once. If 3 is in that away I am trying to input it in a different array only once.

input: 8 3 2 9 8 9 2
output: 2 3 8 9

I cannot find a way to solve this, and I have been trying to solve it for a long time.

C++ :: Assigning Colors To Individual Characters In Array?

Aug 31, 2014

Basically I am making a console RPG (isn't every beginner nowadays?) and I am having an incredible amount of trouble assigning specific characters their own color. e.g. monsters being red, cash being green, etc.

I took out Left, Right, and Down controls because of character constraint.

#include <iostream>
#include <windows.h>
//%%%%%%%%%%%%%% COLOR CALL %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
void setcolor(unsigned short color) {
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);

C# :: Calculator With Buttons - When Click Numbers Or Operators It Goes To String Array

Mar 26, 2012

I have a calculator with buttons, and when I click the numbers or operators, it goes to a string array. So;

Press 3
Press +
Press 2
Press =

and my array is str[0]='3' str[1]=.... so on...

And also I have a C code which calculates the string you entered with some algorhytms and gives a double value as a result. So the question is;

How can I send my STR array in C# to my C program? I mean I want to use my C program as a source code. and How to return that double value to my C# program?

For now, I don't want to change my C codes into C# codes. I want it to keep as is. Just use it as a source code. Is that possible?

C++ :: Random Integers (numbers)

Oct 17, 2014

I'm trying to make a C++ program that generate 6 random numbers ( from 100,000 to 999,999 ), okay, so I wrote a few lines..

Code:
srand(time(0));
for (int i = 0; i < 5; i++)
{
std::cout << 100000 + (rand() % 999999) << std::endl;
}

The problem is, that it generates numbers like this:

117,207
123,303
131,083
... etc etc..

They're all starts with 100K, i want them to be an actual random..

C++ :: Validating That There Are No Integers Only Numbers

May 20, 2013

I am working on a program where the person enters their name and their gross pay. I had to validate that the gross was a number and contained no letters.

I also have to validate the persons name to see if it contains any numbers. The book I am using has an example with only an if statement that says if it is correct or incorrect. I was trying to use <cctype> and toalpha

I just was wondering if there was a way to put it into a while loop or how i would have it ask the user to input their name again. When i tried it just blew up.

Also in the book they use const int SIZE= 8, but I don't want to put a size on the name if I don't have to.

C++ :: Take Numbers And Add One By One As Integers In Linked List

Aug 21, 2013

Let's say that in a txt file named hot.txt, I have this:

12,23,32

And with ifstream I want to take those number, adding one by one as integers in a linked list.

ifstream myList;
char* p= new char;
cin>>p;
myList.open(p);

if(myList.is_open()) {
char* x =new char;

[Code] ....

I know this part is quite wrong :

myList.get(x,256,','); // dafaq
int num=atoi(x);
list->addOrdered(num);

What I wanted to do is to stop before each comma and take that character and store it in the linked list and continue until the end of the file, but I couldnt.

C++ :: Convert Numbers To Integers - Parsing EOF

Oct 26, 2012

Here`s the text:

You have to expect the following input : an arbitrary amount of lines, each line consists of 5 int32 numbers. The full input will be terminated by an EOF.

E.g.:

1 2 3 4 5
6 7 8 9 0
...

You`re then supposed to convert the numbers to integers and do some calculations. I would know how to parse a single line of 5 numbers via scanf(). That`s easy, and that`s exactly what they did in class.

But how do i go about splitting the lines? What about the EOF? Even if could hack something together, by using errno or something, it would be way beyond what they are doing atm. The input is received via user input, ie stdin.

C :: Function For Raising Numbers To Positive Integers

Sep 18, 2013

Write a function that raises an integer to a positive integer power. Call the function x_to_the_n taking two integer arguments x and n. Have the function return a long int, which represents the results of calculating x^n.Here's my code:

Code:

#include <stdio.h>
long int x_to_the_n(int x, int n)
{
int i;
long int acc = 1;

for(i = 1; i <= n; ++i)
acc *= x;
}

[code]...

It compiles OK, but when I run it the program stops after entering the number (x) and power (n).

C++ :: Read Two Positive Integers That Are 20 Or Fewer Digits In Length And Output Sum Of Two Numbers

Apr 30, 2013

so basically my project goes like this:

Write a C++ program that reads in two positive integers that are 20 or fewer digits in length and outputs the sum of the two numbers.

Your program will read the digits as values of type char so that the number 1234 is read as four characters '1', '2', '3' and '4'. After they are read into the program, the characters are changed to values of type int. The digits will be read into a partially filled array and you might find it useful to reverse the order of the elements in the array after array is filled with data from the keyboard.

Your program will perform the addition by implementing the usual pencil and paper addition algorithm. The result of the addition is stored in an array of size 20 and the result is written to screen. if the result of the addition is an integer with more than maximum number of digits(that is more than 20 digits) then your program should issue a message saying that it has encountered "integer overflow".

You should be able to change the maximum length of the integers by changing only one globally defined constant. Include the loop that allows the user to continue to do more additions until the user says the program should end. What I have so far is

#include <iostream>
#include <cstdlib>
using namespace std;
void reverseArr(int a[], int liu);
void addLargeInt(int a1[], int liu1, int a2[], int liu2, int sum[], int& liu_sum);
int main() {
cin.get(next);

[Code]...

C++ :: Turning BMP Image To Min Finite Automata

May 14, 2013

I don't know how to start with it, first thing that came up to my mind was "loop through an array of bits" in bitmap (monochromatic), but I can't get the bits. Here's code I have:

#include <iostream>
#include <fstream>
using namespace std;
unsigned char* readBMP(char* filename) {

[Code] .....

No errors, it's working fine but I just can't get the bits of picture. I've tried to "cout" values form header (width, height) and they're ok, but I wonder how to get representation of picture itself. I thought that this code will give me something like array of 1 and 0.

I have to convert black and white (monochromatic) bmp image to min. finite automata.

C++ :: Turning Recursive To Iterative Form?

Jul 21, 2013

So I have a code like this one below :

void get_sum( INNER_ID id, vector<INNER_ID>& dont_check ) {
vector<INNER_ID> below = get_below( id );
vector<INNER_ID>::iterator second;

[Code]....

I use this algorithm for my "crappy" physic engine, so the point of this algorithm is to get the sum of mass below an object. get_below( id ) function can get the ids of what object is below them.

But before I need ids of the object below them to apply impulse, force, and some other physic stuff.

One object doesn't neccesarrly rest on top of one object, it can rest on 2 object or more.

when I look at it, it resemble a tree, maybe it's not. I just don't really know very much about tree algorithm

I cannot optimize a recursive code so I think, I better turn this into an iterative but I cannot seem to find a way to do that
