Mandatory Coding Conventions
To make your programs portable, you must adhere strictly to the conventions presented in this section. Otherwise, the following problems can occur The length of a C int variable varies from machine to machine. This can cause problems with representation and with binary I O that involves int quantities. The byte order of multibyte binary variables differs from machine to machine. This can cause problems if a piece of code views a binary variable as a byte stream. Naming conventions and the...
atoi atof atol Functions
The atoi, atof, and atol functions convert an ASCII digit string to an integer, float, or long binary number, respectively. The atoi and atol functions convert digit strings of the form - dddddd The atof function converts digit strings of the form -3C 3ddddd.ddd e -3dd3. Each d is a decimal digit. The compiler ignores all leading spaces, but permits a leading sign. Conversion proceeds until the number of digits in the string is exhausted. Each function returns a 0 when there are no more digits...
