Trying to transfer from a CSU to another CSU with community college credit HELP

So I’m trying to transfer from Fresno State to Cal State Fullerton.
I’m taking classes at a community college along with Fresno State classes. When I apply to transfer, will fullerton only look at my gpa from Fresno State or my cumulative with the community college courses I took?

Also I am going to be in sophomore standing at Fresno State. I took a course at the same community college when I was going to be a junior in high school and received a C for that class. When I apply and send in transcripts, will that course I took in high school at the community college also be accounted for in admissions along with the courses I took recently at the community college?

You will need to send official copies of all of your college-level transcripts. So yes, they will see that old C from when you were in high school. Since you are concerned about how CS Fullerton will evaluate your record, you should contact the admissions office and ask. They will be able to tell you what their policy is.
