C++ :: How To Find Path To A Specific Program
Feb 16, 2014
In my C++ program, lets call it menu.exe, I want the user to be able to run a specific program when selecting a specific menu, let's call this program cios.exe.
As the users of my program can have the cios.exe installed in any folder location, I need a way to first locate where the cios.exe is located and then start it with ShellExecute. My problem is : How do I find the path to where cios.exe is located in anyones PC as it can be installed it any folder location.

I have two pieces of code:
Code:
#include <cmath>;
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string>
#include <iomanip>
[Code] ....
I am using the gnu glpk library to calculate a linear program for my matrices. Why I get the error message exit code 3 which apparently means "The system cannot find the path specified"?

I am working on a program in C# that should make a user choose a specific path for the program to work.
The path they are choosing is a path for a game and from that selected path I use coding to load pictures from to the program.
Anyhow
I am able to make the user choose a path and save the selected path in a xml file.
But the user can select ANY path.
How could I do to make the user choose a specific path that I want them to choose?

there's a way to get a path to the recycle bin folder for a specific drive for the current user?
Say, on the input one provides "C:" and on the output you get "C:$Recycle.BinS-1-5-18"

Code that finds a shortest path in a dense graph, using Dijkstra's algorithm in the simple array version. You write a function
struct listnode shortest path(int n, int s, int t, int *dist)
with
struct listnode f struct listnode * next; int vertexnumber; g ;
Being used to return the list of vertices on the shortest path. Your function has the following arguments:
- n: the number of vertices of the graph,
- s: the start vertex,
- t: the target vertex
- dist: the matrix of edgelengths.
The vertices are numbered from 0 to n -1, so s and t are numbers in that range. dist is a pointer to the n * n matrix of edgelengths; vertices which are not connected will be joined by an edge of length 9999. To access the array element dist[i][j], we can use *(dist + i*n + j). Your function should return the list of vertices on the shortest path from s to t, starting with s and ending with t.

im having trouble with a function im writing. Its supposed to find the minimum value in an array and return the location of that value heres what i have so far :
int findLowest (int numb []) {
// findLow will hold the subscript of the lowest value in the array
int findLow = numb[0];
int x;
for (x = 0; x < 5; x++){
if (numb[x] < findLow)
findLow = x;
}
return findLow;
}

A C++ container type called std::map is used to store elements that are formed by a combination of key value and mapped value. How do you iterate through this container and find the value mapped to a specific key?

I am trying to print a specific line from a textfile
e.g
I have a text file called info.txt and inside it contains the id,item name, price, quantity
Code:
1,shirt,100,10
2,pants,50,9
3,pen,20,8
I know how to find a specific word at the line in the file but how do I find and print out the specific line e.g(print out just the entire contents of line 2)?
Code:
string temDescription;
ofstream fout;
int curLine = 0;

I have a templated container that defines a forward iterator.
Calling std::distance on these iterators will generate code that will count the number of iterations it takes to get from the first parameter to the second, by repetitively incrementing.
Internally, the iterators can easily find the distance by a simple subtraction.
What I want to do is overload std::distance for these iterators so that it will take advantage of the simple calculation rather than repetitive increments.
The simple solution of course would be to make the iterators random access, but this would require that they support functionality that is not 'logical' for the container. Access to the container only makes logical sense when iterating one item at a time in the forward direction.
Code:
#include <iterator>
template <typename T>
class Container {
public:
class iterator : public std::iterator<std::forward_iterator_tag, T> {

I got a little question about getting the data path of my c program. I heard something like it's already given in the "int main(int argc, char **argv)". But with witch function can I get it?
For example: The program is called Pathfinder and the path is 'D:Path1Path2Pathfinder.exe'.

I am working on an assignment to enter a number and print all the prime factors of that number. I have that working, but the assignment demands the output be formatted in a strange way which I can't figure out. For example, in my current program entering 10 gets me 25, which is actually 2 and 5. But it should get me: ( 2 * 5 ) but I can't figure out how to do this. On the chance you need it, my code is below:
Code:
#include <iostream>
using namespace std;
int main( )
{
cout << "Number: ";

I have written a program that will input a text file named "inarray.cpp", which contains 10 numbers each separated by a comma, into an array and display the majority on the screen. I am having trouble reading the file in the correct way. For example the numbers have to be on their own separate lines with no commas for my program to work.
ie...
I need to read in 1,2,3,4,5...
but instead i am reading 1
