casting - c++ Why can't I use static_cast to convert char* to int?

Question

number = static_cast<int>(argv[1]);

Error: Using static_cast to convert from char* to int not allowed.

I've tried finding out why on google and I just can't seem to find it. Also, I don't want to get the ascii value, because argv[1] is a number.

e.g. ./prog 15

cout << number; //want it to print 15.

You just try to convert char* to int. You code should be:

int number = atoi(argv[1])
