May 21, 2013I am making a level editor that needs to output a custom map file for use with source code that I will write for a graphics library.
My question is: What do I need to bear in mind when deciding how to structure a custom file type? Also how can I encode a standard bitmap image into my file (the tile set) so that it can all be contained in a single file rather two files; the map file and tile set (.bmp file).
C/C++ :: If Statement Only Evaluates With Intermediate Variable
Jul 10, 2014Odd problem.
if (n <= a.size())
{
evaluates false, despite n being -1 and a.size() (where a is a std::map) being 2913
int test = a.size();
if (n <= test)
{
evaluates true. why does the first one not work?
C++ :: Cout Statement Not Working - Program Outputting Zero For Variable

C++ :: Using Cin That Accept Multiple Inputs
Feb 14, 2013For a program I am required to use a cin that accepts 4 variables. The first describes a function such as add(), remove(), print(), or quit(). The problem is that to use add() I need to input all 4 variables but for remove(), only 2 variable input is needed.
I want the input to be "add 9 James Bond"
or be "remove 341"
Here is my current code.
int command(string command, int Id, string first, string last){
while (command != "quit"){
cout << "customers> ";
cin >> command >> Id >> first >> last;

C++ :: Accept Numbers From User Into Array?
Feb 7, 2015I want to accept numbers from the user into an array and convert into corresponding alphabets. E.g 1 into A, 2 into B, and so on.
This is simple, but the problem is the user is supposed to enter the character # also which I want to display as it is in the output. How can I do this ? What type of array should be used - int or char?
C++ :: Accept Multiple Data Types
Jun 17, 2014Basically I do not want to use a menu, instead just accept either an float or a single character. Then send the data to the appropriate spot based on the user input. I have been unable to convert the char to a float, and even if I did the char would probably only accept the first digit, say user enters '15' it would only read the '1'. I've tried strings instead of char but then unable to use the isalpha function. Do I need a char[] and then iterate through to get the numeric data? Then how do i make '1' and '5' become 15. There is probably a solution. I've also tried to use a loop waiting for the correct data while(!(cin >> letter)) which works but how do I get out if the user enters number.

C++ :: Program That Accept Input For User ID
Oct 28, 2013I need a program to run that will accept an input for user id. It will take the customer input and capitalize the letters, and return invalid id with the user inputted values. Then if it's valid it will add a counter counting the number of letters and numbers. It will keep track until the user puts in !. It seems when I try to pass values from the array to my toUpper function to capitalize it it doesn't seem to work right.

C# :: Accept Two Input Parameter And Returns Two Out Values
Jan 26, 2014class Program {
//Accept two input parameter and returns two out value
public static void rect(int len, int width, out int area, out int perimeter) {
area = len * width;
perimeter = 2 * (len + width);
[Code] .....
why is the static keyword required in the method signature for the rect() method. It will not compile if it is absent. why?
the same is true for this example:
class Program {
static void printvalues(params int[] passedin) {
foreach (var printthis in passedin) {
Console.WriteLine(printthis);
[Code] ....
This code won't compile without the static keyword in the printvalues() method signature. why?
