I am writing code to multiply two int arrays and in my one function i am trying to convert the char array into an int array. I have tested many parts however i can not find the problem.
Code:
struct integer* convert_integer(char* stringInt){
struct integer *converted = malloc(sizeof(struct integer));
int length, i, *ints;
ints = (int *)malloc(10001 * sizeof(int));
length = strlen(stringInt);
printf("stringInt: %s with length of %d
", stringInt, length);
converted->size = length;
How to convert char array into double?,i.e. store char array values into a single double variable. Below is the code that i'm working. Im extracting the value "2255.1682" from char array gpsdata1. I used while loop, extracted the value and stored in "myChar", but i want to store it in double variable "lat1".
How do I convert a string of unknown length to a char array? I am reading strings from a file and checking if the string is a Palindrome or not. I think my palindrome function is correct, but do I do something like char [] array = string.length(); ??
I'm writting program and need to convert int ot char array without simbol. I have tryed snprintf , but his returns array full of simbols if it is initilized elsware return full of garbidge. Is there any elegent way to aceave this? What I'm trying to aceave is liek this:
char buffer[10]; int temp = 1231423; // Do conversation... // After conversation char array should look like this // 1 2 3 1 4 2 3 _ _ _ // without simbol
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
I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.
decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.
whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those? Is there anything unsafe / dangrous about the way the code is now?

I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.
this is the entire code:
#include <iostream> #include <fstream> #include <string> using namespace std;
[Code]....
at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.
I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout joe bob <- nothing is put into (*playerPtr).name, why not? joe bob joe bob seg fault*/ /****************************************************************/ //This is here to show my struct/playerInit
I have a file which contains a year and the name of an associated file to be read. I need to extract the data in the txt file and perform some calculations.
（ year data file） 2004 2004data.txt 2005 2005data.txt 2006 2006data.txt
Here is what I do. I first declare "char yeardata" and then pass "2004data.txt" to it. Then I call yeardata in ifstream to extract the data inside the file "2004data.txt". The problem is that char yeardata is not constant so I cannot pass the file to it. It doesn't work if I change "char yeardata" to "const char yeardata".
Code: int oldnewcomp_temp(char* lcfile) { using namespace std;
Square.cpp:30:8: error: prototype for ‘std::string Square::int2string(int*)’ does not match any in class ‘Square’ Square.h:21:10: error: candidate is: std::string Square::int2string()
I declared the following in header file.
string int2string();
The error is due to variable type does not match. Is there a better way to convert int array to string?
What I'm trying to achieve is a string printed in the following manner:
As a part of a program I am supposed to write, I would like to receive a string from the user (for example: "Hi my name is Joe").
obviously, the string is inserted to an array of chars (arr[0]='H', arr[1]='i', arr[2]=' ',... and so on).
What I would like to do, is to put each word separately in each array cell (for example arr[0]='Hi', arr[1]="my"..., and so on). How can I do this? (I can not use any functions, unless I write them myself).
I am new to programming and have written the code for the following program.
PROGRAM: Input 2 arrays => arrays 1 and 2 from the user each containing 5 elements. Sum is another array which is sum of elements of array 1 and array 2. Convert each of the elements of the sum array into binary. Count number of 1's in each binary element and output it to another array "arr".
Example: arr1 = {1,2,3,4,5} arr2 = {6,7,8,9,10} sum = {7,9,11,13,15} binary of 7 [111], 9[1001], 11[1011], 13[1101], 15[1111] No of 1's in 7 [3], 9 [2], 11 [3], 13 [3], 15 [4] arr array will be {3, 2, 3, 3, 4}
I am not getting the desired output. My code is:-
include <iostream> using namespace std; int main() { int array1[5];
I'm having trouble reading a block of bytes into a vector of short ints. My code is as follows:
Code: FileStream.seekg(2821); vector<short> g_Data; int iter = 0; g_Data.reserve(maxNumOfInts);
[Code] ....
The relevant block of data starts at offset 2821 in the file. Every two bytes are a signed short integer. What's odd is that it's giving me the correct results only part of the time. At offset 1052421 and 1052422 there are two bytes 40 and 1F that are correctly read in as 8000, but at offset 1052415 and 1052416 bytes 88 and 13 are read in as -120 instead of 5000.
I don't see anything wrong with my code, though, unless I'm misunderstanding completely how to convert an array of two bytes into a single float. Is my method correct? Better still, is there some way to just convert en mass an array of bytes into a vector of signed short ints?
