Practice Program






  • Program of Converting Decimal to binary.

    • Solution: through While loop 
    void main()
{
    int i,j=0,n;
    int a[30];

    printf("Enter the decimal number:");
    scanf("%d",&n);


    while(n!=0)
    {
        a[j] = n%2;//storing the remainder at every iteration as element in an array
        n = n/2;//at every iteration we are dividing 'n' with 2
           //and storing its quotient as a new value in of  'n' variable.
     j++;
    }
     j = j-1;
     printf("Number in Binary form: ");
    while(j>=0) //printing the binary form of  a number. 
    {
        printf("%d",a[j]);
        j--;
    }

}

    Output1
    Enter the decimal number: 12

    Number in Binary form: 110

    Output2
    Enter the decimal number: 32

    Number in Binary form: 10000

    Output3
    Enter the decimal number: 44

    Number in Binary form: 10110



    Solution: from do-while loops 
    void main()
{
    int i,j=0,n;
    int a[30];

    printf("Enter the decimal number:");
    scanf("%d",&n);


   do
    {
        a[j] = n%2;//storing the remainder at every iteration as element in an array
        n = n/2;//at every iteration we are dividing 'n' with 2
           //and storing its quotient as a new value in of  'n' variable.
     j++;
    }while(n!=0);
     j = j-1;
     do
    //printing the binary form of  a number. 
    {
        printf("%d",a[j]);
        j--;
    }while(j>=0);

}




    defining a function 'do_binary' which will print decimal number in a binary form. 
    void do_binary(int n)
{
     int j=0;
    int a[10];




    while(n!=0)
    {
        a[j] = n%2;//storing the remainder at every iteration as element in an array
        n = n/2;//at every iteration we are dividing 'n' with 2
           //and storing its quotient as a new value in of  'n' variable.
     j++;
    }
     j = j-1; //decrementing the value of j by 1,
        //because at current j value there is a garbage value.

    while(j>=0)
    {
        printf("%d",a[j]);
        j--;
    }
}

    Using above define function 'do_binary()': 
    void main()
{
printf("Number in Binary form: ");
do_binary(12);
}

    Output1
    Number in Binary form: 110

    Using above define function 'do_binary()': 
    void main()
{
printf("Number in Binary form: ");
do_binary(32);
}

    Output2
    Number in Binary form: 10000

    Using above define function 'do_binary()': 
    void main()
{
printf("Number in Binary form: ");
do_binary(44);
}

    Output3
    Number in Binary form: 10110
