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 At last I could make out that it is not the correct compiler with suitable library or outdated 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?
In this program when I input a string for the variable name,It is getting printed completely, irrespective how many characters are there in the string.But If the string (which is input to the second variable that is game )holds more than 5 characters. the input of the first variable(name) is getting disturbed..why?
look at the below cited output to be more clear about my doubts.
OUTPUT NO:1
Enter your name:LINISHFRANCIS (Note that the input holds more than five chars) Enter your game:GOLF(input is less than five chars)
LINISHFRANCIS loves GOLF(Two inputs are getting printed comopletely)
OUTPUT NO:
Enter your name:LINISHFRANCIS (Note that the input holds more than five chars) Enter your game:FOOTBALL(input is more than five chars)
ALL loves FOOTBALL [Note that "ALL" is the last three letters of FOOTBALL
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?
I'm trying to make colors transparent in c++ using a 3rd party library. I've successful made my background transparent but I feel I'm cheating by not understanding how I entered the value.
"0xff, 0xff, 0xff" is the color white but i'm not sure how it's the color white like with RGB values.
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 am currently starting to attempt to make a program that can move my cursor to certain colors on my monitor. The problem is this seems like it will be 10x harder than I first thought.
Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.
I have a template mock up view using xaml. I have a viewmodel that raises the message property. I binded the message property to a textblock inside my xaml.
Since my messages are different for every viewmodel I have.
E.g.in every viewmodel, I have something like
messagewindow.Message = "This is a new message"; dialogService.ShowDialog(Success, messageWindow);
In one of my messages, I want to make the font bold and different color for a specific message segment.
How can I do that without messing up with the other messages that inherit from the xaml or code behind?
Currently, I'm not using any code behind and a lot of the examples online I've seen use code behind and/or don't have dynamic message textboxes.
I am programming a translator, and I have it so that it detects words with spaces both in front of and behind them, so I did "string.append(space);" where space equals " ". That added a space to the end, but I still need a space added to the front.
I have a problem who must print the sentences who have lenght more than 20 characters. I dont know why, but it prints just the first words. Look what i made.
#include<stdio.h> #include<conio.h> int main()
[Code]....
For instance :
Give the number of sentences : 3
First sentence : I like the website bytes.com Second sentence : I like more the website bytes.com Third sentence : bytes.com
After I compile the program it should print the first two sentences.
1. I finished reading a beginning C book, and in the section about arrays, it says that one string can fit in a character array (char arrayname[]) but there cannot be a string array (string arrayname[]) that have multiple strings. Is
Code: string arrayname[4] = {"one", "two", "three"}; not valid?
My compiler lets me run it and it works, but why is the book saying it's wrong?
2. I know you can represent multiple strings in a character array by:
because [10][4] indicates that there should be four newarrays created with a max of 10 characters each, but is
Code: string multiplestrings[10][4] = ("i love you", "hello come to me", "i don't get C"; "hello world", "what are arrays"; "i am happy", "I am learning how to code"); valid?
Does multiplestrings[10][4] basically create 4 string arrays that have a maximum of 10 different strings within each string array?
How join two strings? basic reason is add given filename little text to end. I try do by hobby not school project program which converts files format x to format y.i dont say which formats becouse reading and writing is almost done. (only little amount code is needed).'
if (letter3==" "){ letter3==letter; PrintCharacterLineEnd();
This is a code. the string "letter3" contains the string " ". What I want to happen is when, letter3 contains the text " " I want to go to the function PrintCharacterLineEnd.
I need to make a small program with a function with this prototype: void f(char *a,char *b) that adds two numbers represented as strings without using conversion operators or other tricks.
I have a vector I want to add book titles to, then i want to print my updated vector. This is best I have come up with but the program fails at the getline line. why?
string book; cout << "Enter book to add: "<< endl; getline(cin, book); books.push_back(book); for(int i = 0; i < books.size(); ++i) { cout << i+1 << ". " << books[i] << endl; }
The problem with this code is that there are no errors showing, but when i compile the program, the if else statements do not carry out as they should do. Both if statements show the same answer, for example the second if statement. If I type Y or N then I get the same thing, 'You will now choose an event'. How do i get rid of this problem? Is char supposed to be used or string?
