why isnt initgraph getting recognized in my program? - c++
I have programmed a code for displaying a GUI menu in Turbo C++ but I don't know why it wont recognize initgraph
This is the output message
BGI Error:Graphics not initialized
when i tried a simpler program on graphics in Turbo C++ it said egavga.bgi not found but it was there in the bgi file in my turbo c++ folder
Also when i tried to put the location of the bgi in initgraph it doesnt do anything
this is the program code

key and mouse input
i have a question: (i use winows, visual studio) i making a program and i need to read keyboard and mouse input istantly so like getch() (because if i use cin i need to press fullstop new line evry time). i have this: char p; while (running) { if (_kbhit()) { p = _getch(); switch (p) { case 'w': mx = -1; map(player, mx, 0); break; case 'a': my = -1; map(player, 0, my); break; case 's': mx = 1; map(player, mx, 0); break; case 'd': my = 1; map(player, 0, my); break; case 27: running = false; break; } } } the problem is with _getch() i can't read mouse imput. so how i can get this?
How to make a button that will go to the previous menu in ncurses
I am pretty new to c++ and ncurses, so sorry if my question is weird or obvious. I managed to make a simple tui program that will do various tasks, my problem is that I have no back functionality or something that would loop the program. I want to be able to go back to the main menu after accessing one of the submenus and I want to make the program repeat after it's done so I won't have to keep opening it over and over, so do you have any solutions that I can apply? Thank you in advance This is my code: int main(int argc, char ** argv) { int i=0; string input; initscr(); noecho(); cbreak(); curs_set(0); int yMax, xMax; getmaxyx(stdscr, yMax, xMax); WINDOW * menuwin = newwin (0, xMax, 0, 0); leaveok(menuwin, true); refresh(); wrefresh(menuwin); keypad(menuwin, true); string choices[4] = {"Youtube","Music","Anime","Games"}; int choice; int highlight = 0; int option = 0; while(1) { for (i=0;i < 4; i++) { if(i == highlight) wattron(menuwin, A_REVERSE); mvwprintw(menuwin, i+1, 1, choices[i].c_str()); wattroff(menuwin, A_REVERSE); } choice = wgetch(menuwin); switch(choice) { case KEY_UP: highlight--; if(highlight == -1) highlight = 3; break; case KEY_DOWN: highlight++; if(highlight == 4) highlight = 0; break; default: break; } if(choice == 10) { break; } } werase(menuwin); switch(highlight) { case 0: { menu2(); break; } case 1: { menu3(); break; } case 2: { menu4(); break; } case 3: { menu2(); } default: break; } endwin(); return 0; }
How to debug why Arduino is breaking a while loop?
I first added an infinite loop. Dugme is a variable for loop. But I couldn't break the loop. That’s why, when I enter the loop, I can’t exit. void otoac() { long duration, distance; while(dugme==1) { int distanceR = 0; int distanceL = 0; delay(40); if(distance<=24) { moveStop(); delay(100); moveBackward(); delay(300); moveStop(); delay(200); distanceR = lookRight(); delay(200); distanceL = lookLeft(); delay(200); if(distanceR>=distanceL) { turnRight(); moveStop(); } else { turnLeft(); moveStop(); } } else { moveForward(); } distance = readPing(); } } I have an code that when I click on case:'X' it goes in automatic mode (application). I have here the code for when I click out of 'X' that's 'x' (little x) it needs to stop but it doesn't stop. This is the code for the 'x'. void otokapa() { dugme=0 motor1.setSpeed(0); motor2.run(RELEASE); //turn motor1 off motor2.setSpeed(0); motor2.run(RELEASE); //turn motor2 off } Someone on YouTube only gave me this answer: I added a while loop to the command, as well as a contradiction to the command, meaning, the action that the car will do when the triangle is not pressed, which is nothing. More code: void loop(){ if(Serial.available() > 0){ command = Serial.read(); Stop(); switch(command){ case 'F': forward(); break; case 'B': back(); break; case 'L': left(); break; case 'R': right(); break; case 'G': onsol(); break; case 'I': onsag(); break; case 'H': arkasag(); break; case 'J': arkasol(); break; case 'W': onac(); break; case 'w': onkapa(); break; case 'X': otoac(); break; case 'x': otokapa(); break; } } } and dugme: on top of all the code int dugme=1; and dugme is only in void otokapa and in otoac while(dugme==1)
Is this in essence what your problem looks like? int dugme = 1; // one and only definition of this (ODR) void otoac() { long duration, distance; while(dugme==1) { } } void otokapa() { dugme=0; } void loop(){ if(Serial.available() > 0){ command = Serial.read(); Stop(); switch(command){ case 'X': otoac(); break; case 'x': otokapa(); break; } } } Possible errors violation of ODR. if loop and otoac runs in the same thread you will never get to the serial again.
hold screen for accepting arrow keys
for using arrow keys, first it has to be stored for analyzing it. That's why I am using scanf to store it. But when I try to run this code, and when I press up key, then it is showing ^[[A and when I press enter then this ^[[A removes and program exit without printing printf statement of printf("%s",c). and printf("UP\n"). #include <stdio.h> int main() { char c[50]; scanf("%s",&c); printf("%s",c); if (getch() == '\033'){ // if the first value is esc getch();// skip the [ getch();// skip the [ switch(getch()) { // the real value case 'A': printf("UP\n"); break; case 'B': printf("DOWN\n"); break; } } return 0; }
You will find it easy if you use the ncurses library. Just go through the documentation to see how to install it. After installing read the part on Interfacing with the key board Here is a sample code #include <ncurses.h> int main() { int ch; initscr(); raw(); keypad(stdscr, TRUE); noecho(); while(1) { ch = getch(); switch(ch) { case KEY_UP: printw("\nUp Arrow"); break; case KEY_DOWN: printw("\nDown Arrow"); break; case KEY_LEFT: printw("\nLeft Arrow"); break; case KEY_RIGHT: printw("\nRight Arrow"); break; } if(ch == KEY_UP) break; } endwin(); }
move cursor in c++ using gotoXY and kbhit
I want to move the position of symbol "A" in the terminal via the following code in c++, but the terminal closes and seems it does not enter the for loop. I don't know where I am wrong. I will be grateful if you help me: 'w' should move it up 's' should move it down 'a' and 'd' to right and left #include <iostream> #include <conio.h> #include <string> #include <Windows.h> using namespace std; void goToXY(int x=0,int y=0) { HANDLE h=GetStdHandle(STD_OUTPUT_HANDLE); COORD c; c.X=x; c.Y=y; SetConsoleCursorPosition(h,c); } int main() { char symbol='A'; int X=0, Y=0; goToXY(X,Y); cout<<symbol; for(;;) { if(kbhit()) { char ch = getch(); switch(ch) { case 'w': goToXY(X,Y-1); cout<<symbol; case 's': goToXY(X,Y+1); cout<<symbol; case 'a': goToXY(X-1,Y); cout<<symbol; case 'd': goToXY(X+1,Y); cout<<symbol; } } getch(); return 0; } }
1) You forgot to add break; after each case-body. 2) And you've put return 0; in the body of for-loop, so your program stops after first iteration. Try this: for(;;) { if(kbhit()) { char ch = getch(); switch(ch) { case 'w': goToXY(X,Y-1); cout<<symbol; break; case 's': goToXY(X,Y+1); cout<<symbol; break; case 'a': goToXY(X-1,Y); cout<<symbol; break; case 'd': goToXY(X+1,Y); cout<<symbol; break; } } } getch(); return 0;
You have not used the break; statement after each case in your switch statement. Hope this helps. switch(ch) { case 'w': goToXY(X,Y-1); cout<<symbol; break; case 's': goToXY(X,Y+1); cout<<symbol; break; case 'a': goToXY(X-1,Y); cout<<symbol; break; case 'd': goToXY(X+1,Y); cout<<symbol; break; }
