C++ :: Converting String To Char Array

Mar 30, 2014

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);

[Code]...

C :: Converting Netpay To String

May 18, 2014

Code:
void convertNetPay(float netPay, char *netPayString){
int numHuns, numTens, numOnes;
char OnesTable[9][8]={"One","Two","Three","Four","Five","Six","Seven","Eight","Nine"};
char ResultString[10+1];
char TensTable[9][8] = {"Ten","Twenty","Thirty","Forty","Fifty","Sixty","Seventy","Eighty","Ninety"};
char TeensTable[9][10] {"Eleven","Twelve","Thirteen","fourteen","fifteen","Sixteen","Seventeen","Eighteen","Nineteen"};
float cents;

[Code] ....

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.

C++ :: Converting String Into A Long Double

Mar 11, 2013

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>
#include <stdlib.h>
#include <string>
#include <sstream>
string test = "12.345";
long double test_longd = strtold(test.c_str(),NULL);

C/C++ :: Converting Dollar Amount To String

May 18, 2014

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
...

[Code] .....

So that goes my entire instruction on the assignment and I will start my code and be probably asking quite a bit of questions!

Here is my code so far:

Spoiler

#include <stdio.h>
#include <stdlib.h>
#include <cstring>
void convertNetPay(float netPay, char *netPayString) {
int numHuns, numTens, numOnes;
