C++ :: Assigning Colors To Individual Characters In Array?
Aug 31, 2014
Basically I am making a console RPG (isn't every beginner nowadays?) and I am having an incredible amount of trouble assigning specific characters their own color. e.g. monsters being red, cash being green, etc.
I took out Left, Right, and Down controls because of character constraint.
#include <iostream>
#include <windows.h>
//%%%%%%%%%%%%%% COLOR CALL %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
void setcolor(unsigned short color) {
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);
I'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:
Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word int CompareLetter(char array[], char guess, int numLetters) { int i;
[Code....
However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.
In my program, I am fed a string that contains integers such as Code: *str = "45678" and my program is simply supposed to read the number in and store each given number in a separate spot in an integer array. So basically, when my program has finished running it should be stored like:
however, this just seems to return an impossibly high garbage value when I do. I'm assuming the way I'm trying to store it is 'illegal', but I cant seem to find online a proper way to do it.
so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?
Code:
int main() { int i; char ch[5]; for(i = 0; i < 5; i++) { scanf("%c",&ch[i]);
I have an array of characters. I am trying to find "houston". The only way I can think of to do this is to use a for loop and check each individual character. Is there an easier way to do this?
char string[] = "Fishing tourism miami atlanta dallas houston";
I am having problem in writing the code for the problem "To assign the elements of 1-D integer array into 2-D array of integers such as if the array is 1,2,3,4,5,6 The resultant 2-D array should be like :
I want to assign a char to an array inside an if statement after the user has input the grade as an integer, but it has to fill an array with characters, such as:
char grades[5]; int grade; char A, B, C, D, F; cout << "Enter da grade" << endl; cin >> grade; if (grade < 59) { grade[0] = F;
[code]....
A, B, C, D, and F won't transfer to the array, thus giving me the uninitialized variable error in microsoft visual studio 2010.
I need to dynamically build a control file for a SQL loader but when tokenizing line values read from a file i am unable to work/assign the last value to a variable even though i can print the actual token value while in the loop.
Below is the code snippet i have and get:
Code: //headElement declared as headElement[42] //getCol function is used to decode column keys present in line being read istringstream ss(line);
I have a problem with rotating an array and assigning it to different variables. This is wat i have done.
Code:
#include<stdio.h>#include<stdlib.h> #include<conio.h> #include<math.h> int n[16],a[16],n1[16],n2[16],n3[16],n4[16],n5[16],n6[16],n7[16],n8[16],n9[16],n10[16],n11[16],n12[16],n13[16],n14[16],n15[16],n16[16], c=0; int x[16],i,j,k; int rotate();
I'm trying to write a very simple program that takes values in through variables, and stores those values in a two dimensional array. The values are already passed into the void function, I need to have those values write to their corresponding locations in the array.
void planeSeats(int seats[13][6], int ticket, int ticketRow, int ticketColumn) { if (ticket = 1) { if (ticketRow >= 1 && ticketRow <= 2) {
[Code] ....
For example, lets say that ticketrow is 2 and ticket Column is 4 .
What I need is for ticketRow and ticketColumn to assign that data to seat[ticketRow][ticketColumn], turning it into seat[2][4]. How to do that.
I need to dynamically build a control file for a SQL loader but when tokenizing line values read from a file i am unable to work/assign the last value to a variable even though i can print the actual token value while in the loop.

I'm working on a program in C++ that is supposed to read in a file, store the content of the file into a 2D array, assign characters to each of the numbers in the array and store in a char array, and print both of these arrays. It's then supposed to go through the initial array and make sure that each number doesn't differ in value from it's neighboring numbers by more than 1, correct these errors by replacing these numbers with the value of the average of their neighbors, assign characters to this corrected array as it did before, and print both arrays.
The character assignments go as follows:
0=blank 1=. 2=, 3=_ 4=! 5=+ 6=* 7=# 8=$ 9=&
I have the code written that opens the file and loads the array, but where to go from there. To me the obvious, although probably not best, way to do the assignments is to go through the array with a for loop and use a series of if statements to check for the value of the number at each index and assign the appropriate symbol.
Here is the code I have so far:
#include <iostream> #include <fstream> using namespace std; int main() { int size = 100, i, j; prog >> size; int **numArray = new int* [size];
I have a simple problem about memory allocation.In the function Nr_elements() i assign a value which represent the elements of array. The pointer p is initialised with the address of variable n, but when i compile i dont know why but dont work. This function return a pointer.
Code: #include<stdio.h> #include<stdlib.h> int *Nr_elements(); int *allocate(int); void deallocate(int *); [code]....
I want to assign prime number to the element of an array.
#include "stdafx.h" #include <iostream> #include <conio.h> //For Console Input/Output function like clrscr & getche using namespace std; //Using the "standard" namespace of iostream class
I'm okay with 2-dimensional arrays, but when I get to 3 or more, I can't seem to wrap my head around how to assign and/or pull values from specific parts.
To give an example, let's take the following example:
We know that a player can take up to 5 total quests, and each quest can have a max of 5 tasks.
Let's assume I have the following multi-dimensional array holding all of a players quest data:
quests[0] = 78;// Store the questID quests[0][0] = 3945;// Store the 1st creature ID quests[0][1] = 2230;// Store the 2nd creature ID quests[0][2] = 3045;// Store the 3rd creature ID quests[0][0][0] = 2;// Store how many needed of the 1st creature quests[0][1][0] = 5;// Store how many needed of the 2nd creature quests[0][2][0] = 13;// Store how many needed of the 3rd creature
As we know, the above code can't be done. How do I assign certain values to each specific dimension?
I'm trying to create an array of function pointers and then assign compartilbe functions to them, so I can just call *pf[0](xxx);
The functions are all of the type
void func01(unsigned char*, int, int)
how would I create an array of function pointers and assign the address of the functions to them? So I could call them like
ptrToFunction[i](charBuffer, 10, 20);
I've read a bit on line and I thought I could do it but so far I've failed.
It seems trivial and I feel I'm close but close isn't good enough.
I'd like to assign the fuction addresses like this: for (int i=0; i<10; i++) if (i==1) ptrToFunction[i]=func01; if (i==2) ptrToFunction[i]=func02; etc.
The actual logic is somewhat different than this but this close.
I am attempting to read values from a file into a 2d array temp[31][2] (31 rows, 3 columns).I only want the values from the file to be read into the first two columns.I believe I am accomplishing that but when I go to print the array, I expect the first two columns to have the file data and the third column to have all zeros. The third column, however is printing such that the value is the next row/first column.
I'm not sure for instance why on the bottom loop for line 1 it doesn't print:
Where col is a 'vec4' struct with a double[4] with values between 0 and 1 (this is checked and clamped elsewhere, and the output is safely within bounds). This is basically used to store rgb and intensity values.
Now, when I add a constant integer as a pixel value, i.e.:
buffer_rgb[i] = ((unsigned char)255;
Everything works as it should. However, when I use the above code, where col is different for every sample sent to the buffer, the resulting image becomes skewed in a weird way, as if the buffer writing is becoming offset as it goes.
You can see in the 'noskew' image all pixels are the same value, from just using an unchanging int to set them. It seems to work with any value between 0-255 but fails only when this value is pulled from my changing col array.
Whole function is here:
// adds sample to pixel. coordinates must be between (-1,1) void Frame::addSample(vec4 col, double contrib, double x, double y) { if (x < -1 || x >= 1 || y < -_aaspect || y >= _aaspect) {
I am currently using Dev-C++ 4.9.9.2 compiler for creating a C project. I need few strings to be printed in a different color.
Code: #include<stdio.h> #include<conio.h> int main(void) { textcolor(RED); cprintf("Hello world "); system("pause"); }
While I use " textcolor(RED) " it says: 'RED' undeclared, first use in this function.
If i make it: " textcolor(3) ", it says: [Linker error] undefined reference to textcolor & undefined reference to cprintf.
have been searching for a solution on google since morning. At last I could make out that it is not the correct compiler with suitable library or outdated <conio.h> header file.
I had switched from turbo(or borland, I don't remember) to Dev-C++ compiler due to some kind of library issue. Now I guess I'll have to switch to some other IDE. Which one is that, I don't know yet. There was another thread also about this topic, but didn't provide any solution.
Is there any method to upgrade certain header file (I don't think so)? What would be the best IDE with updated libraries?
I want to write a function called DrawLineSegments.This function must change the color of lines at every corner where the corner angle is greater than 60 deg (Assume that there is a function called checkangle). The color sequence must be black, red, green, blue, and repeat this sequence after the fourth color.
I want to use a new color for BaseColor in iTextSharp.
I can easily set a new color using RGB values from 0 to 255.
However, if I want to adjust the alpha value (and I know alpha ranges from 0 to 1), I can't make the alpha 0.5 because it's not an integer in the definition of BaseColor.
public BaseColor(int red, int green, int blue, int alpha);
So I can set my BaseColor like below:
static BaseColor newColor = new BaseColor(192, 192, 192);
but I can't use a non-int value for alpha. How can I easily convert double alpha values to integer values? What would be the range for alpha in int values and how do I, e.g., set the alpha value to 0.5 in int values?
EDIT: btw, I found online something like this: int alpha = (pixel >> 24). I don't understand why 24 and how can I break that into chunks I understand?
void generate_all_color_pairs(){ int foreground; int background; int i = 0; for(foreground=0; foreground<8; foreground++){ for(background=0; background<8; background++){ i++;
[code]....
but according on several sources, some terminals suport more colors.Is there any way to determine how many colors the current terminal supports?
Assume you want to use a loop to process an array of characters starting from the beginning of the array. You want the loop to stop when you read the null terminator character from the array. Fill in the loop test condition that will make this work correctly.
index = 0; ch = array[index]; while ( _____________________________) { // process the character index++; ch = array[index]; }
