C++ strange output converting string to int -


I am writing a program that converts binary string to decimal. Before I actually started this method, I wanted to validate my output. I have the following code: 

  int get_val () {int sum = 0; (Int new_bits = size; num_bits> 0; num_bits--) {printf ("string sub ii is% i \ n", num_bits, int (bin [num_bits])); }}

When I input a string of 16 zeros, I get the following output: 

  string sub 16 24 string sub 15 string sub Is 14 is 0 string is sub 13 is string sub 12 23 string sub 11 is 0 string is sub 10 is 0 string sub 9 is 0 string sub 8 22 string sub 7 is 0 string sub 6 string sub 5 is 0 string sub 4 21 string sub 3 is 0 string is 2 is 0 string is sub 1 is 0

If I input all the hards So why would I get different prices?

Edit: bin "0000000000000000"

until the question is updated So maybe this example code helps. It changes a binary string in an integer. I tried to keep my code and variable name as much as possible. 

  #include & lt; Stdio.h & gt; # Include & lt; Stdlib.h & gt; #include & lt; String & gt; using namespace std; Int main () {string bin = "000111010"; Int size = bin.length (); Int sum = 0; {Sum & lt; for num (num_bits = 1; num_bits & lt; = size; num_bits ++) & Lt; = 1; Sum + = bin [num_bits - 1] - '0'; } Printf ("The converted binary string is% s:% I \ n", bin.c_str (), yoga); } As already mentioned in the comment, here the main challan is to convert the ASCII character '0' and '1' to integers 0 and 1, which by decreasing the value Is done '0'. In addition, I have changed the string order of the string because in this way, you can change the integer after each bit and always set the value of the current minimum bit.
