Heart in C/C++ Programming

C/C++ Graphicl Heart

This code will make a graphical Heart in C programming which will move around your screen and will change it's colors, It's a Great Program Try Now!

code:

 #include <graphics.h>

#include <math.h>

#include <conio.h> // For kbhit

#include <dos.h>   // For delay

double hearta(double k) {

    return 15 * pow(sin(k), 3);

}

double heartb(double k) {

    // Invert the y-coordinates to flip the heart

    return -(12 * cos(k) - 5 * cos(2 * k) - 2 * cos(3 * k) - cos(4 * k));

}

void drawHeart(int xOffset, int yOffset, int color) {

    setcolor(color);

    for (int i = 0; i < 1000; i++) {

        double x = hearta(i / 100.0) * 20 + xOffset;

        double y = heartb(i / 100.0) * 20 + yOffset;

        putpixel(x, y, color);

    }

}

int main() {

    int gd = DETECT, gm;

    initgraph(&gd, &gm, "C:\\Turboc3\\BGI");

    int xOffset = 200, yOffset = 200;

    int color = RED;

    int direction = 1;

    while (!kbhit()) { // Check for key press

        cleardevice();

        drawHeart(xOffset, yOffset, color);

        xOffset += direction;

        if (xOffset > getmaxx() - 100 || xOffset < 100) {

            direction = -direction;

            color = (color % 15) + 1; // Change color

        }

        delay(50); // Delay for 50 milliseconds

    }

    closegraph();

    return 0;

}

Digit Cheaking System in C/C++

 

 C/C++ Digit Cheaking System

This code can cheak how much digit number you have typed if your number is 3 digit than this code will reply Yes else this code will tell How Many digit Number you have typed.

code:

#include <stdio.h>

int main() {

    printf("Type Here to Enter Something... :");

    int num;

    int count = 0;

    scanf("%d",&num);

    printf("\n");

    if(num > 99 && num < 1000){

     printf("Yes it is 3 digit number \3 \4 \2 \1 \5 ");

    }

    if(num < 99 || num > 999){

     printf("\nNo it's not a 3 digit Number\n");

     }

     if(num > 1){

     printf("\n");

     }

     else{

     printf("\nError You Have Entered Wrong Input!\n");

     }

      if (num < 0) {

        num = -num;

    }

    if (num == 0) {

        count = 1;

    } else {

        while (num != 0) {

            num /= 10;

            count++;

        }

    }

      printf("Number of digits: %d\n", count);

    printf("\n");

    return 0;

}

 C/C++ Automatic Password Generator

This code can generate a unique password as your desired lengeth. Example if you want 12 letters unique set of password than this code can make it for you!

code:

#include <stdio.h>

#include <stdlib.h>

#include <time.h> // ASR

void generate_password(int length) {

    char characters[] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*(){}?<>,';:/\\";

    char password[100]; // Fixed size array to avoid dynamic allocation issues in Turbo C++

    int i;

    srand(time(0));

    for (i = 0; i < length; i++) {

        int randomIndex = rand() % (sizeof(characters) - 1);

        password[i] = characters[randomIndex];

    }

    password[length] = '\0';

    printf("Generated Password: %s\n", password);

}

int main() {

    int length;

    printf("Enter the length of the password: ");

    scanf("%d", &length);

    if (length > 99) {

        printf("Length too long! Please enter a length less than 100.\n");

        return 1;

    }

    generate_password(length);

    return 0;
