Hi,
I am a new Julia user, and in programming in general, and I would like some help to understand why updates in the array “pressure” in the code below does not carry over after the for loop.
Note that a similar code in python seems to be working fine. Please let me know what I am missing and, perhaps, a way to get it right.
Thank you in advance for you help and time,
```julia
function Create_Fault_List(s, fault_list_size)
pressure=zeros(1,s)
fault=[]
for i=1:fault_list_size
push!(fault,Create_Pressure_Type(pressure))
end #close fo loop
return fault
end
type Create_Pressure_Type
pressure::Array{Float64}
end
#List with 5 elements
s=5 #size of the pressure vector
fault_list_size = 10 # size of the fault list
fault=Create_Fault_List(s, fault_list_size)
index=3 #index to update in the vector pressure
for k=1:length(fault)
#I would like to update the index element of the array pressure
fault[k].pressure[index]=k
#It seems to work, as you can see here
println("pressure vector inside the loop ",fault[k].pressure)
end
println("\n")
#However here the pressure array has only the last element
for i=1:length(fault)
println("pressure vector outside the loop=", fault[i].pressure)
end
```

You put the same array into every element…
```julia
push!(fault,Create_Pressure_Type(copy(pressure)))
```
if you want to use different arrays all with the same value.
