A)Decimal to Binary Conversion

#include <stdio.h>
#include <stdlib.h>
int main()
{
int a[10], n, i;
system("cls");
printf("Enter the number to convert: ");
scanf("%d", &n);
for (i = 0; n > 0; i++)
{
a[i] = n % 2;
n = n / 2;
}
printf("\nBinary of Given Number is=");
for (i = i - 1; i >= 0; i--)
{
printf("%d", a[i]);
}
return 0;
}

B)Decimal to Hexadecimal Conversion

#include <stdio.h>

int main()
{
long decimalnum, quotient, remainder;
int i, j = 0;
char hexadecimalnum[100];

printf("Enter decimal number: ");
scanf("%ld", &decimalnum);

quotient = decimalnum;

while (quotient != 0)
{
remainder = quotient % 16;
if (remainder < 10)
hexadecimalnum[j++] = 48 + remainder;
else
hexadecimalnum[j++] = 55 + remainder;
quotient = quotient / 16;
}

// display integer into character
for (i = j; i >= 0; i--)
printf("%c", hexadecimalnum[i]);
return 0;
}

c) Binary to Decimal Conversion

#include <stdio.h>

void main()
{
    int num, binary_val, decimal_val = 0, base = 1, rem;

    printf("Enter a binary number(1s and 0s) \n");
    scanf("%d", &num); /* maximum five digits */
    binary_val = num;
    while (num > 0)
    {
        rem = num % 10;
        decimal_val = decimal_val + rem * base;
        num = num / 10;
        base = base * 2;
    }
    printf("The Binary number is = %d \n", binary_val);
    printf("Its decimal equivalent is = %d \n", decimal_val);
}
