    The document describes a program that takes a number as input, finds all the factors of that number, and displays the factors on an LCD while playing a buzzer sound between each factor. It includes the source code for the program which takes the number as input from switches, defines functions to find the factors and convert numbers to strings, and uses an LCD and buzzer to sequentially display and sound the factors.

    PROGRAM 8
    QUESTION:
    Design and implement a program that outputs factors of a number
    (input through switch) on LCD and LED with buzzer in between every factor.

    SOURCE CODE:
    #include <LCD.h>
    sbit buzz=P0^3;
    unsigned int count = 0;
    unsigned char a[16];
    unsigned int f[20];
    void input()
    {
    unsigned int val = 0;
    if (INT0 == 0)
    val += 8;

    if (INT1 == 0)
    val += 4;

    if (T0 == 0)
    val += 2;

    if (T1 == 0)
    val += 1;
    if (val != 0)
    count = val;
    }
    int factors(int n)
    {
    int j=0,i=1;
    for(i=1;i<=n;i++)
    {
    if(n%i==0)
    {
    f[j]=i;
    j++;
    }
    }
    return j;
    }
    void intToChar(long n)
    {
    int i = 0, j = 0;
    for (i = 0; i < 16; i++)
    {
    a[i] = ' ';
    }
    i = 0;
    while (n != 0)
    {
    a[i] = (n % 10) + '0';
    i++;
    n = n / 10;
    }
    i--;
    while (j <= i)
    {
    char temp = a[i];
    a[i] = a[j];
    a[j] = temp;
    i--;
    j++;
    }
    }

    void dispnum(unsigned int number)


    {
    int j=number;
    RD=!(j&1);
    j>>=1;
    WR=!(j&1);
    j>>=1;
    TxD =!(j&1);
    j>>=1;
    RxD=!(j&1);
    delay(10);

    void main(void)
    {
    int i=0;
    int c=0;
    buzz=1;
    LCD_INIT();

    while (1)
    {
    input();
    if (count == 0)
    {
    LCD_WRITE("Enter a number", 0, 0);
    }
    else
    {
    LCD_WRITE("Factors of ", 0, 0);
    delay(20);
    intToChar(count);
    LCD_WRITE(a, 0, 8);
    delay(20);

    LCD_WRITE("are ", 1, 0);


    c=factors(count);
    for( k=0;k<c;k++)
    {
    intToChar(f[k]);
    dispnum(f[k]);
    LCD_WRITE(a, 1, 5);
    buzz = 0;
    delay(4000);
    buzz=1;
    }
    count = 0;
    }
