Neither 1 nor 100 are prime numbers. To be prime, a number must have exactly two factors; itself and 1. Neither 1 nor 100 fall into this category of numbers.
The number 1 is neither prime nor composite because it has only one factor; itself. If 1 were to be regarded as being prime, then the Fundamental Theorem of Arithmetic would not hold. That is; every whole number greater than one can be expressed uniquely (except for their order) as the product of prime numbers. But if 1 were prime then the uniqueness aspect would fail because n = 1*n = 1*1*n = 1*1*1*n and so on. 1 is therefore a special class of number that is neither prime or composite, we simply refer to it as a unit.
The number 100 is a composite number because it has many factors besides itself and one; 1, 2, 4, 5, 10, 20, 25, 50 and 100 are all factors of 100.
Any algorithm that regards either the unit 1 or the composite 100 as being a Prime number is clearly not a valid algorithm.

How can I write a program to display prime numbers from 1 to 100?
Write a function that implements an algorithm that checks to see if a particular integer is prime (returning a boolean). Write a program that uses that function on each number from 1 to 100, and if true, displays that number.

What does it mean to find the prime factorization of a composite number?
Finding the prime factorization of a nunber means that all the factors will be prime. For example, 100: 4 X 25 = 100, but 4 and 25 are not prime numbers, so you have to factor them. 4 X 25 2 X 2 X 5 X 5 = 100 All the factors are prime, so this is the prime factorization of 100.
