How do I assign a string to an integer?

In Java, we can use Integer.valueOf() and Integer.parseInt() to convert a string to an integer.

2. Use Integer.valueOf() to Convert a String to an Integer. This method returns the string as an integer object.

How can a string be converted to a number in C?
