Thread: Simple Question

you can't just output a whole array like that (except for strings, and even then you need to use the %s format specifier) you need to step through the array and print out each element one by one

unless it is required by your assignment I would suggest you drop the "char to number that is binary to base 10 equivalent of number that is binary" approach and take a "base 2 to base 10" approach, it's much simpler imo

        printf("Enter a positive binary inteer to be converted (6 bits): ");
        scanf("%s", a);

        for (i = 0; i < 6; i++)
        {
                z[i] = a[i]-48;
                scanf("%d", &z[i]);
        }


        while (binary)
        {
                decimal += binary % 10 * a;
                a *= 2;
                binary /= 10;
        }
        printf("Decimal Representation of the Binary Number: %d\n", decimal);

        while(decimal > 0)
        {
                num = decimal % 8;
                result += num * pow;
                pow *= 10;
                decimal /= 8;
        }
        printf("Octal Representation of the Binary Number:  %d\n", result);

}

See this is my entire program thus far. I need to convert the input string to binary integers and then run it through the conversions of different radixes but its not working out. the conversions to the different radixes are correct but I can't get the input to change to an integer then pass through.

break that up into subroutines

u r declaring a as an int and inputting it using %s, also in the for loop u're using it as an array.the condition inside the first while loop looks as if it will result in an infinite loop.
