I have a board where a character is. I need to ask the user whether they want to move it up, down, left right. They are allowed to enter 3 move per turn. like up, up, left. How do I do this?
#include <iostream>

i want to make moving button or moving box clickable as i am making a game in which i move picture boxes and user clicks on it and his scores increases. but i was unable to do so , so i tried the same concept with buttons but no results.

Double values are stored in text file. 23.5 36.8 34.2 ... My teacher told me to read them character by character and then make words, like i have to read "2" "3" "." "5" and now have to make it or treat it as word and then using atoi(). I have to convert it into double. but i dont know how to do this....
View 5 Replies View RelatedI encounter this from a library:
( *(reg8 *)(pinPC) |= CY_PINS_PC_DATAOUT)
From my understand the cast (reg8 *) applies to the result of the bitwise OR. But what is the left most asterisk doing?Is it just dereferencing the casted pointer?
I am creating and implementing a left and a right rotation to balance a bst into an avl tree. I have made and tried 5 different codes that are commented in the functions left_rotate() and right_rotate() but none have run correctly.

I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.
How do I write an a program that will read an input file character by character?
View 1 Replies View RelatedHaving trouble getting my square to move to the left my code and instructions of what i am suppose to do is below. No sure how to move my square or if I am even going in the right direction as to writing code to do so. Note that it is only part of my code ( part 2 of project)
Part 2:
Write a graphical application that draws a square and then moves it.
Get the x and y coordinates for the top left corner of the square from the user using the get_int() member function of cwin. Get the length of a side of the square from the user using get_int() as well. Now draw the square to cwin according to the user input.Ask the user how many units to the left they want to move it using get_int() again. Then move the square, clear the screen, and draw it again.
// Part 2 //
/* command output to declare the x,y value and 1 side length of a square through user interaction( Has user input intergers) */
int x_value = cwin.get_int("What is the x_value of the top left of the square?");
int y_value = cwin.get_int("What is the y_value of the top left of the square?");
int side_length = cwin.get_int("Input the length for one side of the square:");
/* Data type for the 4 corners of the square */
Point e;
Point f;

This works, if just loops through till it doesn't find a space or tab than counts the index at that point then uses substr to get rid of any spaces/tabs, it's a small function and uses a goto. how to do it?

I have a character at a co-ordinate, say (3,4) for example, and I need to get him to (10,15). I would like him to move one block every tick or half a second, so that you can see him moving towards his destination. How to achieve this?

I am getting this error when compiling my program with quincy:
Error: I value required as left operand of assignment
The program is meant to calculate how much parking costs based on the amount of hours in a park and what type of vehicle it is. the error is coming from my function definitions which i have just started to add in.
Code:
float calcCarCost (char vehicletype, int time, float car)
{
if ((time > MINTIME) && (time <= 3))
calcCarCost =( CAR * time );
}
The error is on line 72 which is:
calcCarCost =( Car * time);
I should probably point out CAR is already defined as a constant with a numerical value given and time is previously asked to be input in when the program runs.

View 2 Replies View RelatedSay I have a function pointer with this definition:
void ( *pressFunc ) ( void*, void* );
And i did this function:
void functionWithOneArg ( void* testPtr );
And i did this
pressFunc = &functionWithOneArg;
One. Would C actually let me do this? ( Assigning a function with one argument to a function with two )
Two. If so, what would happen to the second argument that is passed the function when its called? Does it just get 'cut off' and only the first argument is passed?
How do you add a value to the beginning of a string instead of the end?

then

Basically, my function receives an array. For example:
u8 array = {1, 2, 3, 4, 5}
I don't need the first 2 elements, how can I access the array's 3rd element as head? I plan to throw the received array to another function.
array = array[2];
somefunc(array);
Will somefunc get index 2 as start of the array?

something in this part is making it go wrong, it displayes the original array fine but when it tries to shift it it goes haywire. EDIT: also how would i add elements onto the array?
