Hi:
Thank you for your reply.
I am using std::string, C++.

Your slashes are backwards
"C:Program Files/Local_user/Visual Studio 2005/Project/Debugger/cosc.exe"
should be
"C:Program Files\Local_user\Visual Studio 2005\Project\Debugger\cosc.exe"
/////////////////////////
std::string sPath="C:Program Files\\Local_user\\Visual Studio 2005\\Project\\Debugger\\cosc.exe";
std::string sSearch="cosc.exe";
// If looking for the string directly
int nIndex=sPath.find(sSearch);
TRACE("Found \"%s\" at index = %d\n",sSearch.c_str(),nIndex);
/*
If you need to search out the filename
from a given path
*/
nIndex=sPath.rfind("\\");
std::string sExtract=sPath.substr(nIndex+1,sPath.length()-nIndex);
TRACE("Found '\\' at index = %d\n",nIndex);
TRACE("Filename from path is \"%s\"\n",sExtract.c_str());

i get this error :

do i type the Array wrong ?

how i put my code in the site like quote ? (so it can take the tabs that has in Visual studio Eviroment)
if( x == y )
{
y = x ;//used spaces
}
and not
if ( x ==y)
{
y=x;
}
or you only can do it with hiting space many times

It was html fault ( < min ) took it as a Html tag :/
i think my fault is on writing the name of array

Hi i would like to inform me anyone (or give me link) about data types
int float double long
like : int = 1,2,3,4,5 natural numbers
float = [0,1) ? 0.054353234243 0.9999999999999999 0.000000 but not 1 ?
double is ?
long is ?( bigger than int ? but still natural numbers?)
how i put them in printf("%", )? printf("%d %s " ,int , str) these 2 i know 
ALso what about casting ? int x = (int) (while this is double)
i can combine a float + int to become a double ?

Well int are not natural numbers: they are signed and bounded (i.e. there is a max int and a min int).
float are floating point numbers, i.e. you can think about them as real numbers, but, in fact they are somewhat different (being composed by sign, maintissa, exponent, they are bounded and have variable precision...
BTW what do you think about a good book on C language programming?

dont know suggest me one . University gave meh 3 C & C++ language programming books but i think their build sux :/ i learnt more things via codeproject and google than from the book :P (well maybe i am a bit lazy to search 900 pages) but i do searching them and still dont find anything to understand the Data types
about int yes they can be negative too !:P
Deitel & Deitel C language programming is he one

Well,
Kernighan & Ritchie [^] is must.

Well, should such a topic have been included in the books? Just because a book does not contain exactly what you happen to be looking for at the moment does not necessarily make it the book's fault. It just may be that data types were not in the book's scope.

Which is why an int cannot be a natural number.

also about long and double ? and how i put them inside strings ?
printf("%lf",double) ? i do this and it print me 0.00000 :/

What should it print? What is the value of double?

a fault in my code :P now it prints the right values !
thank for the intresting

I dont know how to create a fuction that return 2 values and how i give these values in 2 varablies in (int main() )
i found on google something but i think its for C#
I am working on C 
#include <stdio.h>
#define N 10
#include <stdlib.h>
#include <math.h>
void insert_array ( int p[] , int nCount , int a , int b);
(double , double) find_values( int p[] ,int nCount );
void print_array1( int p[] , int nCount);
void print_array2( long p[][2] , int fCount);
int main()
{
int pinakas[N];
double mid , s ;
(mid , s) = find_values(pinakas , N);
printf ("%lf %lf",s ,mid);
return 0;
}
(double ,double) find_values(int p[] ,int nCount )
{
double mid ;
double s ;
for ( int i =0 ; i < nCount ; i++ )
{
mid = mid + p[i];
}
mid = mid/nCount;
for (int z = 0 ; z < nCount ; z++)
{
s = s + (p[z] - mid)*(p[z] -mid);
}
s = pow((s/(nCount -1)) , (1/2));
return (mid , s);
}

I'm no C++ expert, but won't it be easier to send references of the variables?
void find_values(int p[] ,int nCount, double *mid, double*s )
--Star
|
|
|
|
|
well not because you dont know mid and s .
fuction find_values will find the mid and s (and return them)
but i dont know what reference is about !
|
|
|
|

When we reference a variable we send its address(i.e. original variable not a copy), while in usual function calling, you send a copy of the variable.
In other words, any changes made to a variable, will remain in the function. But if you sent a reference, any changes to that reference of the variable will return to main.
Hope that explains it a little.
Well there is another way, you can create a global array of type double that holds two elements, knowing that you will assign mid and s as the first and second elements respectively. When you call the function it will access the array, and you can add the values of mid and s. Later you can access them in main.
Or if you know about referencing a little, you can create an array inside main, and send its reference -the address- and you can assign its values inside the function. The function will return void, but because you sent the array's reference (not a copy) you will assign the values of mid and s.
Hope it's clear.

Well, from the logical (i.e. language independent) standpoint, functions can get three categories of arguments:
(1) The IN arguments, i.e. values set by the caller and used inside the function. This category is the most used one.
(2) The OUT arguments, i.e. values set by the function and returned to the caller.
(3) The INOUT arguments, i.e. values set by the caller and returned (usually modified) by the function.
Of course, you need two arguments of the second category (OUT).
In C language every argument is passed by value, hence you can implement OUT arguments only by means of pointers (as already suggested by Star08):
void find_values(int p[] ,int nCount, double * pmid, double *ps);
int main()
{
int pinakas[N];
double mid , s ;
find_values(pinakas , N, &mid, &s);
printf ("%lf %lf",s ,mid);
return 0;
}
Of course you need to know a bit of pointers usage.
