How to convert string to currency type.

/*Currency Conv Control Module*/
#include <stdio.h>
#include "currencyconv.h" /* defines constants, declares functions */
int main(void) {
float us_dollars;
float currency;
int user_input;
[Code] ....
This is $$ converter program I created that is split up over 3 files. It takes the users input in US Dollars and converts it to the currency selected. When executing the program I am encountering a small problem. It actually isn't converting anything and returns 0.00 dollars.
I would like for it to convert the amount entered into the currency selected. I would also like to add in the print statement the type of currency the user has selected.
i have given a project for currency conversion program with add,delete,search,display option. but i was thinking if it can update the currency rate from internet at beginning.
View 3 Replies View RelatedI want to see if the value of a string equals a certain text. But I can't make it. There are two problems :
1) It seems 'tolower' doesn't work with strings. What to use then?
2) When I delete tolower, it works, but I have an output of "You didn't enter 'add'" even when I do enter 'add'. What's the problem? Is it due to the null byte? What to change?

I am working on a program where i prompt the user for his/her name and i have to verify that the name only contains alphabetic characters.
here is my coding. It works to an extent i just can't get it to work the way it is supposed to.
#include <iostream>
#include <cstring>
using namespace std;
const int SIZE = 50;
int main()
{
char name[SIZE];
cout << "What's your first name?" << endl;
[Code]...
when someone types in a name with only alphabetic characters it outputs valid name for how long the name is. For Ex: bob is three characters so it would output valid name three times. also when you put in a name with a number or character at the end it outputs valid name for the correct characters but also outputs the invalid character and invalid name which its supposed to do. the valid name should not be showing up though.
I need to create a line chart that will be universal for every currency. As Y it will display value of currency, as X it will display time when that value was established.
For drawing I think of using Windows.UI.Xaml.Shapes.Line and Windows.UI.Xaml.Controls.Canvas
What I want to get is something like image below but it would have to draw correctly scaled chart for every currency which is the biggest problem(I think it is).
For every currency I will probably have to get minimal and maximal value which will be used to properly scale a chart(I will probably also have to get rendersize of canvas or something).
The user will choose the range of time and then the correct chart must be drawn (For example 04-11-2004 to 11-03-2007)
It is a windows store project.
I want to make such application in which user make directed graphs along with relations between them. After that application show that which graph properties are proved in this graph e.g Reflexive, Irreflexive, Symmetric, Anti Symmetric, transitive etc

I'm a novice with C programming and i have to solve an error in the following code. The code works like you enter a password called "uoc" and it shows as OK. But surprisely when you entered another password as "Cambridge" it works fine too.
I think that the problem is in the array declaration but i'm checking resources and no success!
Code:
#include <stdio.h>

struct {
char str[8];
char ok;
} data;

I am trying to read a "password" from a file, the file only contains the password... Here is my code:
int i=0, ch;
char password[25];
FILE *fp = fopen("C:UsersOlintoDocumentsNetBeansProjects est.txt", "r");
if (fp == NULL)
printf("Erro ao Abrir");
[Code] ....
puts(password); When I read the string password, it outputs -> abcd123"
I don't know where it takes the (") because the password on the file is abcd123...
this is really important i searched an example code about "Username and Password Validation between Server and Client" through internet a LOT and i couldn't find anything..

Okay, so I have a science fair project and I decided on doing a series of programs that show the simpleness behind hacking a password. Each program increases in complexity starting with a four digit password, and ending with a 10 digit letter and number combo that is case sensitive. Right now I need to figure out a way to have my program be able to convert chars into ints, so that I can do a counter and then I also need to be able to convert the ints, back into chars.

So I need to make a program that recieves a 10 letter only password, then once the password is entered, it starts off as AAAAAAAAAA...AAAAAAAAAB...AAAAAAAAAC...etc, Until it gets the correct password, which it then stops. This is for a science fair project on cyber security not for malicious purposes ...
