The 4 Language Criteria For the question 5 is : Readability, Reliability, Writability, and Cost

An integer constant is a decimal (base 10), octal (base 8), or hexadecimal (base 16) number that represents an integral value. Use integer constants to represent integer values that can't be changed. If an integer constant begins with 0x or OX, it's hexadecimal. If it begins with the digit 0 , it's octal. Otherwise, it's assumed to he derimal No white-space characters can separate the digits of an integer constant. These examples show some valid decimal, octal, and hexadecimal constants. 6. (15 points) Create a regular expression, DFA, and Regular Grammar for the integer constant. 7. (5 points) Analyze the above problem for the 4 language criteria. 8. (10 points) Write code that that lets you know if a string is an email address or not. Based on the definition from problem 1. 9. (15 points) Write code that that lets you know if a string is an floating point literal or not. Based on the definition from problem 4. 10. (15 points) Write code that that lets you know if a string is an integer literal or not. Based on the definition from problem 6
