I was working on a program which compares sequences of characters, counts the differences between them, and displays them. I had the sequence inputted as a string (into a vector so any number of sequences could be chosen), and then, the way I tried to check the strings for differences, was by converting the string to a (multidimensional) vector of chars:
vector< vector<char> > sequencesC;
for (int a = 0; a < sequenceCount; a++) {
cout << "
Enter sequence " << a+1 <<" name: ";
cin >> sequenceNames[a];
cout << "
[code]....
However, it crashes (as shown above) when I try to set, by a for loop, every char of a multidimensional vector (sequencesC) to the same char of the data vector. Is there any way I can convert the string to a char vector?
I am having trouble accessing a one-dimensional vector as a multi-dimensional one.I have a MultiArray template class, and it is accessed using the function operator. It accesses elements through the expression row * m_columns + col. The row and col are the two inputs to the operator while the m_columns is the width/number of columns in the array. There is also a version that accesses the array with one number. Its underlying representation is a one-dimensional vector.The problem is when I try to load a level:
For a rather complex and strange reason that I won't explain right now, I need to have this going on in my program.
class FVF{ private: vector<vector<float>> data; //Contains fvf data for Direct3D stuff public:
[Code].....
The FVF allows this Model3D class to also be compatible with file handling methods I've got, but here's the problem. D3D buffers require an array to feed them the information, and I know that for a single dimension of vector I can use vec.data(), how to do this for multiple dimensions.
I think the best Idea I've got so far is to set the vector within the Model3D class as a pointer, then I can union it with a float pointer... Once I can guarantee the information is correct and complete, manually transfer the contents of the vectors into the float pointer.. (The union is to reduce memory needed instead of having the data repeated in vectors and arrays)
In one of my programs I have a 3x3 array of string that I use to display the outcome to rock, paper, scissors, and another 1x3 used for a number guessing game. I have the arrays declared in the header file as follows:
//Games.cpp string rpsOutcome[3][3] { //row 1 { "Both of you picked rock, you tied. Try again", "You picked rock, the computer picked paper, you lose",
[code]....
From what I've read, Im pretty sure thats how your supposed to initialize multidimensional arrays (using the nested braces), but when I build the project, I get the following error:
I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol
This is the function that opens the file :
Code: // opens mol file, reads in rows to string vector and returns vector vector<string> get_mol_file(string& filePath) { vector<string> mol_file; string new_mol_line; // create an input stream and open the mol file ifstream read_mol_input; read_mol_input.open( filePath.c_str() );
[Code] ....
The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.
All structures are vector<char>. when i do the above my characters form Query and Subject are copied in my new vector called StrJoin but the size of that vector is twice the size then it should be.
I've got something I'm trying to accomplish, but crashes my program.
I've got my server and client code.
Having the client send a message they type (char Chat[1024]) And the server receiving the chat (char recv_chat[1024]) only to send it to all connected clients again. Which the server sends the recv_chat.
The client receives it (char recv_chat[1024]). This works, and the client gets the right info. However, I'm trying to store it using a vector. I'm sure I've tried any way possible.
Client storing vector pseudo-code:
vector<char*> SaveChat; int main () { while (true) { if (newClientConnected) {
[Code]....
This doesn't work, and crashes my application. I've tried changing the vector to string, const char*, basically anything I can with no avail.
I was assigned to print a linked list but as a vector of char (I cannot use the normal string type) , this is what I have:
char* List::asString(){ Node* ite = new Node(); ite= first;//ite is like an iterator of the list for(int i=0; i<sizeOfList; ++i){//sizeOfList is the total of node of the list
[Code] ....
But when I print that, I get a bunch of weird symbols...
I have the codes for such a problem where, to create a program that counts how many times the second string appears on the first string. Yes it counts if you put 1 letter only, but if you put 2, it is an error. As an example. If the first string is Harry Partear, and the second string is ar, it must count as 3. Here's the code:
Code:
#include <iostream> #include <conio.h> using namespace std; int main ()
I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.
// Get value from ListBox. char selectedValue[256]; memset(selectedValue, NULL, 256); SendMessage(GetDlgItem(hWnd, IDC_LB_CURRENTSCRIPT), LB_GETTEXT, selectedIndex, (LPARAM)selectedValue); // Convert to string. string val(selectedValue);
I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it cin.ignore(); string line; getline(cin, line); if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT cout<<"match"<<endl; }
Above is the code I have tried using and it stores data under *chr, it however only stores one letter rather than the entire word like for example string.
This sends the buffer to a LIN modem. My question is: can this be done better. If I have a astring of hex numbers like "09 98 88 55 42 FF 00 00 FF BD 89". How could I send this without manually makng a char with hex numbers?
I have a question on conversion between char & string. I have cut & pasted the part of the code from my C++ code and my function "decryptPwd" uses C style code with "char" etc.
I need to pass a string (mypwd) somehow to this function after conversion & then compare it to another string (newmypwd).
I tried - "decryptPwd(mypwd.c_str())==newmypwd.c_str()" but it did not work.
.. #include <string> .. char* decryptPwd(char hash[64]); main () { string mypwd; string newmypwd; if (decryptPwd(mypwd)==newmypwd)
