I am trying to convert a 1d string array to a 2d but i couldnt do it. Heres my code so far,
for(i=0;str2d[i][j]='';i++)
{
for(j=0;str2d[i][j]=' ';j++)
{
str2d[i][j] = str1d[k];
k++;
}
}
str1d is a paragraph btw.I tried using NULL instead of '' but didnt work either.
In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);

For Example, it the entered string is: 0324152397 I want it to get stored in an array like-[0] [3] ...[7]. Secondly the string entered may be of any length that is defined only at run time. So, I also need to calculate string length. How could I do that.

I have to convert my netpay which is a float to a string So if I input a value of say, 356.26 it should output "the sum of three hundred fifty-six and 26/100 dollars" . My program function works for the sum of three hundred but after that it spits out garbage.

BASICALLY, I have to convert netpay (float to string). Theoretically if I have 666.66, my program here should output the sum of "six hundred sixty-six and 66/100 dollars".
i think i need to convert a double to a string, we are working in visual studio doing a program. when i run the calculator i'm not getting the answer i need instead its giving me 0.0 when it should be reading 0.5, here is the code i'm using

Quick code for converting strings to Dates in C++.
Example: What is the date:
User response: 12/05/14
Any way I can code this to recognize it as a date, and make it so that the date is sortable? Not referring to the system date, but a user input date.
how to convert from string to date in c++? Example: 17 mar 2012 to 17/03/2012

I have a problem with converting a C++ string into a long double. In order to do this, I used the function strtold, but the result I get is only the integral part, that is: if for example the input string is 12.476, I only get 12 as the converted long double value. This happens with atof too.
Here is my code:
#include <stdio.h>

string test = "12.345";
long double test_longd = strtold(test.c_str(),NULL);

So I have to convert ("a499.9") into a char and a float while ignoring the a.
I have the string stored in a buffer and found how to get the char, 4. But I don't know how to get 99.9 as a float.
Here is my code so far.
#include <string>
using namespace std;

How to get that double out?
I have a vector<string> of times that I want to convert to vector<double>. The time string is in the form 00:00.000. Is there a STL or something like it algorithm or function to do this, otherwise what would be the best way to do this with a function.

I'm quite new to programming and working on an algorithm for the program so we would have to change that into a workable code for our final program.
This is the algorithm teacher gave us for reference (with the functional decomposition):
3.9.3 convertNetPay()
// convertNetPay(in netPay, out netPayString)
char * convertNetPay(float netPay);
void convertNetPay(float netPay, char * netPayString);
Algorithm:
convertNetPay(in netPay, out netPayString)
Declarations: numHuns, numTens, numOnes as integer
OnesTable as array[9] string = {"One", "Two","Three", ...."Nine"}
"One" --> 0
"Two" --> 1
"Three" --> 2
