How do I add arrays into my program!?!?

sl02ggp (27)
Trying to make this setup for my arrays:
Print Output Format: Print total resistance followed by the values of each resistor.

For series: (Example)
Total series resistance is 2.123 kOhm for 3 resistors:
1000 kOhm, 1000 kOhm, 123 kOhm

For parallel: (Example)
Total series resistance is 500 Ohm for 2 resistors:
1000 Ohm, 1000 Ohm


Its not compiling need help!...i think my parallel code is incorrect along with my arrays.

fixed my errors, compiles but doesn't run the way i want it to.

k...here is what im trying to do..never really gave a proper description of my program :P

Trying to write a program to calculate the resistance connected either in series or parallel. Using arrays in solving the problem/

Prompt the user to select series or parallel.
Promtp the user to enter the number of resistors connected.
Read/get the value of each of the resistors
calculate the resistance.
Output the resistance according to the following:
Print Output Format: Print total resistance followed by the values of each resistor.

For series: (Example)
Total series resistance is 2.123 kOhm for 3 resistors:
1000 kOhm, 1000 kOhm, 123 kOhm

For parallel: (Example)
Total series resistance is 500 Ohm for 2 resistors:
1000 Ohm, 1000 Ohm

Avoid division by 0

took out the while (true)

runs a little bit better but:

now trying to get the format output correct:

"Print Output Format: Print total resistance followed by the values of each resistor."

For series: (Example)
Total series resistance is 2.123 kOhm for 3 resistors:
1000 kOhm, 1000 kOhm, 123 kOhm

For parallel: (Example)
Total series resistance is 500 Ohm for 2 resistors:
1000 Ohm, 1000 Ohm

this is what shows up now:

can anyone assist me with this? please? on why the resistor values aren't printing like I stated above and what i have to do to modify my code to print output this way??
