data type mismatch in criteria expression
I have an array of char pointers:
Code: char *input_args[MAX_ARGS];
And I have this function:
Code: BOOL parseArgs(char **input_args[], input arg_num);
I am trying to pass a pointer to this char pointer array like this:
Code: parseArgs(&input_args, args_num);
But the compiler is complaining:
Code: warning: passing argument 1 of 'parseArgs' from incompatible pointer type ...
note: expected 'char ***' but argument is of type 'char * (*)[20]'
Tried a bunch of stuff but nothing works.
error says "cannot convert 'int*' to 'int' in function main()
and also
type mismatch in parameter in function sort(int,int)
Heres the code:
#include<iostream.h>
#include<conio.h>
void main() {
void sort(int,int);
clrscr();

I am making a program that allows you to add two big numbers that are larger then what int can handle together. I think I have done everything to accomplish this but when I try to instantiate the program I get a error Expression must have a class type.
Here is my main file that is supposed to instantiate the program.
Code: #include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <conio.h>
#include "LargeIntegers.h"
using namespace std;

#include<iostream>

I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:
Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int largest(const int arr[], int lowerIndex, int upperIndex) {
int max;
[code]....
Now try to print the array backwards:
//Use a recursive algorithm to find the largest element in arr:
int largest(arr[], lowerIndex, upperIndex);//error: expected an expression
return 0;
}
my doubt is :- in what data type the intermediate result of an expression is stored? like for expression 2+3*1/2 , i think the intermediate result for 1/2 is stored in the form 0.5 but for expression 2+3*1/100 , i think the intermediate result for 1/100 is stored in the form 0.01 so i am not sure if the compiler use dynamic type ie, changes with need. or it always stores in high precision like:- for 1/2 its 0.5000 and for 1/100 also 0.0100 or something like that.

// Purpose: To write a program that displays the number of millimeters higher the current level the ocean level will be in
// in 5, 7, and 10 years.
# include <iostream>
# include <string>
using namespace std;
int main() {
float X = 10;
string Y="";
[Code] ....
But I get the following error message:
IntelliSense: expession must have integral or unscoped enum type
three times in a row for lines 25, 27, and 29 and I don't understand or know why?
In case the purpose does make sense here are the directions:
2.7: Ocean Levels
Assuming the ocean’s level is currently rising at about 1.5 millimeters per year, write a program that displays
•The number of millimeters higher than the current level that the ocean’s level will be in 5 years,
•The number of millimeters higher than the current level that the ocean’s level will be in 7 years,
•The number of millimeters higher than the current level that the ocean’s level will be in 10 years,
Output labels:
Each value should be on a line by itself, preceded by the a label of the form:
In X years the ocean's level will be higher by Y millimeters.
where X is the number of years (5, 7 or 10) and Y is the value you calculate.
in this area and I have this error Invalid expression term 'out' and Identifier expected; 'out' is a keyword

I have an EDI file whose structure is given below. This file has multiple records, each record contains a header (e.g EDI.DD.0000000001.20130809), then contents (i.e multiple paragraphs of text) and then footer (e.g End of Report/No EDI Activity). I have to read that entire file using regular expression using three groups.
I am using following regular expression to read the file.
(?<header>[A-Z]{3}.[A-Z]{2}.[0-9]{10}.[0-9]{8}) | (?<footer> (EndsofsReport|NosEDIsActivity)) |
(?<content>(?<=k<header>).*(?=k<footer>))
That expression reads the "header" and "footer" in respective groups properly but didn't pick the contents between header and footer in "contents" group.
I have changed the font of header and footer in below file to understand the format. I am using asp.net 3.5 framework.

I am starting a new thread. So I try to sort an array with qsort and then save the new order, so this means if I have a list like:
4 3 7 2 [0] [1] [2] [3],
after sorting it becomes:
2 3 4 7 [3] [1] [0] [2] <== this is what I want to have!
Which works fine, with following code:
void qsort_my(int *a, int l, int r, int *array_order) {
int j;
if( l < r ) {
j = split( a, l, r, array_order);
qsort_my( a, l, j-1, array_order);
qsort_my( a, j+1, r, array_order);
[Code]...
I tried to add the criteria :
(if (a[i] != a[j] || (a[i] == a[j] && array_order[i] > array_order[j])))
before calling switch_pos, but it is not working since sometimes you swap two numbers like:
11 9 15 9 <= here the 11 and 15 are swapped, but the two 9's will never be swapped <=> compared.I mean I could run it again with the array_order on the first parameter position, but this would increase my runtime enormously!
Procedure to Compare 2 Strings with the following criteria
coding of the following function -
I have absolutely no clue where to start -
Given the following sets of numbers -
1154 1179 2154 2554 2484 2144 4515 1144 1517 4815 1481
Given the Index number of 1154
I want to search the numbers for the Index number of 1154
The search will return a True if I can find 3 or 4 same digits between the Index number and the 8 numbers
The search also have the following criteria -
meaning that -
1154 when compared to 1154 == true
1154 when compared to 1179 == false
1154 when compared to 2154 == true
1154 when compared to 2554 == false
1154 when compared to 2484 == false
1154 when compared to 2144 == false
1154 when compared to 4515 == true
1154 when compared to 1144 == true
1154 when compared to 1517 == true
1154 when compared to 4815 == true
1154 when compared to 1481 == true
the index number can also be of type - 1234, 1123, 1112, 1111
There are many questions on the web on how to fix a specific signed/unsigned mismatch, and the solution is usually just making one variable unsigned.
I have a grid (x,y) which should be unsigned, since you can't have a (-5,-3) sized grid. However, I have a Direction object which should be signed, since I can have a (-1, -1) direction. The problem is when I do something like Location_x + Direction_x > grid_x which throws the signed/unsigned mismatch warning.
I'm trying to create a new data type Data declared as int. What comes up to my mind is to create a structure like
Code:
typedef struct Data {
int number;
} Data;
but when I need to use the data I need to go through the structure. Is this a good way to declare a new data type?

I want to create a new data type called an inf_t. It's basically infinity (which for C++ is 1.7e+308). The only reason I want this is because I want to overload the cout << operation to print out INF/inf. Should I do this in a struct?
Code: struct inf_t {
private:
double inf = 1.7e+308;
};
std::ostream& operator << (std::ostream &stream, inf_t inf) {
stream << "INF";
return stream;
}
I want to find the size of the data type with out using sizeof() operator.
