Conversion of character string to integer
How do I convert a character to an integer? For example if I have a character '1' how do I convert it into an integer type one. There is a good news and bad news. The bad news is that my character array starts out with "non-integer" characters and "integer" characters that gets tokenized and pushed into a queue data structure. The good news is that I'll be able to check if each element is an integer is not by some sort of test.
So, my question is how would you convert that character into a mathematical element? Thank you.
queue <char> Q1;
// after loading characters string, we need to see if each element is an integer
t = Q1.front();
if (t == integer)
// do mathematical operation
// do something else
