Specifing a particular number in a string

[Lyanette]

I am new at this!!!


I am trying to write a program that converts binary to decimal. My thought is to manipulate the power of 2 with a counter starting at zero. Then use the power function to get the power of 2. Each time that answer needs to be multiplied by a particular number in the binary number. How do I specify that number.?

How are you storying your number?

cout << myint << endl;

Doesn't work?

If your number is stored in a string, you can just use things like strtol().

Assuming you've read the binary number in as a string called num, use:

num[0] - '0'  //to get the first binary digit
num[1] - '0'  //to get the second binary digit
num[2] - '0'  //to get the third binary digit

and so on.
