C++ :: Unlimited Storage For Variables
Jul 12, 2013I am working on a project and I need to save and work on very big numbers, let me take u an example :
E.g. I want to find the biggest prime number ( 2,3,5,7,... ) but I just know about int, double and etc. which have unlimited storage .
How to save very big numbers on the memory and use them ?
C/C++ :: Unlimited Number Of Arguments - Float To String Conversion
Mar 21, 2015So, I'm supposed to do : Create a function with unlimited number of arguments, which forms a dynamic string based on the following form (%d, %s, %f, %lf, %c), with the following prototype:
char*create(char*form, ...);
The function is supposed to have the following output:
create("Peter is %d years old and is in %s-%c class.",7,"second",'A');
-> Peter is 7 years old and is in 7-A class.
create("His GPA is %lf.",4.96);
-> His GPA is 4.96.
create("His favourite subject is math!");
-> His favourite subject is math!
I've managed to do the following :
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdarg.h>
char *create(char *form, ...) {
char *res =(char*)calloc(1,1),*pos_int,*pos_float,*pos_str,pos_char,*pos_long;
[Code] ....
The part with %d and %s string was not that hard, but now I'm supposed to convert %f and %lf to string, I've tried using sprintf but I've had no luck so far, another problem is the fact that I've gotta use lists to complete the task. I've been trying to convert float to string for the past 2 hours, but I'm drawing a blank now.
C++ :: Variadic Templates - Enter Unlimited Amount Of Types In Function
Feb 25, 2013I'm looking for a way to enter an unlimited amount of types in the <> part of a template function, I found Variadic templates but I'm not sure if it can do it, all the examples I've found are similar to the C argument list and don't use the <> part of the template at all.
I tried this, but the overload is ambiguous?
#include <iostream>
#include <typeinfo>
template<typename T>
void stuff() {
std::cout << typeid(T).name() << "

C :: Define Array Type With 4 Elements?
Jan 18, 2015How can I define type MARKS which will be able to hold 4 elements just like array? I want to access it just like normal array elements using brackets []. In the following struct I want to use such type.
Code:
typedef struct {
MARKS ** pointers;
} ARGUMENTS
void main(){
ARGUMENTS arguments;
[Code] ......
Purpose of the struct ARGUMENTS is to hold 4 pointers to string. I want to mark few positions in string so I can simple access them. E.g. name=John
Code:
arguments[0][0]=0; // begin of the param name
arguments[0][1]=3; // end of the param name
arguments[0][2]=5; // begin of the value
arguments[0][3]=8; // end of the value I mean not to save int but the pointer to the corresponding position.
C :: Multiple Elements - Define Array Size
Jan 11, 2015I have array of 100 elements and I'm trying to write elements which index is smaller than the index of the maximum element of the array. My problem is that I can't determine how big this array should be . I found which is my biggest index.
Code:
#include <visual_2013.h>
#include <stdio.h>
#include <stdlib.h>
#define DIM 10
void enterArray(int x[]);
void array2(int x[]);
int maxAndIndex(int x[], int n, int *index);
int main()

Aug 21, 2013I have the following method:
public string[,] StringConvert_tblVFWPost(DataTable dt1) {
string[,] stringArray = new string[dt1.Rows.Count, dt1.Columns.Count];

The error I'm getting is "Cannot implicitly convert type 'string[*,*]' to 'string'". So that tells me what the issue is. However, I'm not sure how to fix it.
How do I change this method, so that it properly returns my two dimensional array?
C Sharp :: Array Size Limitation Is Too Small
Mar 24, 2013I am having difficulty with arrays because of the limitation of the size of the arrays that I can declare. I need sizes that are very large and windows or C# does not allow me to create bigger than the following for example:
public static int[] gaPoints = new int[20000000000000000000 + 1];
I get an error message saying that "integral size is too large".
I need to be able to declare sizes that are even much larger than the abovementioned size.
How can I circumvent this problem?
Do I have to use something other than arrays?

Jul 24, 2013I am trying to understand how to get the following value from a define. The code i am trying to understand is as follows:
Code:
#define RADIO_CONFIGURATION_DATA_RADIO_DELAY_CNT_AFTER_RESET {0xF000}
Code:
#define RADIO_CONFIGURATION_DATA {
Radio_Configuration_Data_Array,
RADIO_CONFIGURATION_DATA_CHANNEL_NUMBER,
RADIO_CONFIGURATION_DATA_RADIO_PACKET_LENGTH,
RADIO_CONFIGURATION_DATA_RADIO_STATE_AFTER_POWER_UP,
RADIO_CONFIGURATION_DATA_RADIO_DELAY_CNT_AFTER_RESET,
RADIO_CONFIGURATION_DATA_CUSTOM_PAYLOAD
}
and also have this
Code:
typedef struct {
U8 *Radio_ConfigurationArray;
U8 Radio_ChannelNumber;
U8 Radio_PacketLength;
U8 Radio_State_After_Power_Up;
U16 Radio_Delay_Cnt_After_Reset;
U8 Radio_CustomPayload[RADIO_MAX_PACKET_LENGTH];
}
tRadioConfiguration;
so then in the api i have the following
Code:
for (; wDelay < pRadioConfiguration->Radio_Delay_Cnt_After_Reset; wDelay++); .
so my question is how do i declare my variables, correct terminology ?, to achieve this.

Aug 19, 2012I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.

C++ :: How To Define A Class Which Have Two Members
Sep 16, 2013I want to define a class, which will have two members, for example, vaporPressureStatus and vaporPressure
enum vpStatus_t {nonesense, unknown, known, saturated};
class pore_t {
public:
vpStatus_t vpStatus;
double vaporPressure;
};
when vpStatus is nonsense and unknown, the vaporPressure should not have a value; and if I calculate out a value for vaporPressure, the vpStatus can be set as known.
I am wondering if there is any set, pair or other structure can hold this two members together, so that when I change one's value, the other guy will also change accordingly.
