Hi, I'm very new to c programming. I was tasked to create a c program where the user enters the number of digits and the binary number, and the output will the binary number separated by 3 spaces and the decimal equivalent of the binary number.
E.g
Input:
Enter the number of digits : 4
Enter the number in binaries : 1001
Output
1 0 0 1
The decimal equivalent is : 9
I tried using pow function but I didn't go far..
I also used an if loop so the number of digits is limited to a maximum of 9
> Enter the number of digits : 4
Presumably, you used scanf with %d to read this.
> Enter the number in binaries : 1001
What did you use to read this?
One you have a sequence of 0 and 1, then you just need a loop over
answer = answer * 2 + x, where x is your 0 or 1.
also using scanf with %d for the binaries
That's pretty vague: a scanf call can have various format specifiers and various corresponding arguments. Show the code.
That is probably a mistake. You can make it work for small binary numbers, but it's not very logical and hard to error check.Quote:
