As you can see in line six, we have str1, which is a string that contains a representation for the number 572. So if I want to convert that string to a number, I can use atoi, so let me do that in line seven. I will assign to a new integer value that's called an X the return value of atoi, with an argument of str1. That's it. So that's the beauty of atoi. It's very simple to use. Now let's print it out. Let me say X equals this value, and the variable will be X. That's it for part one. Now let's get to part two, where we will use STR to long. Now, if you look at the string in line 11, you'll see that str2 has two numbers. The first one is a decimal number 123, that's what I meant by it, and the second one is a hexadecimal number…
