I want to print my output in Julia, I have written it in the form presented below but I want to use a for loop to make it more concise.
Any help on how to write the code below using for loop will be appreciated please.
@show objective\_value(model)
@show value(w[1])
@show value(w[2])
@show value(w[3])
@show value(w[4])
@show value(w[5])
@show value(x[1])
@show value(x[2])
@show value(x[3])
@show value(x[4])
@show value(x[5])
@show value(X)
@show value(y)

Please make a new post, rather than commenting on an old one.
Just write a for loop over the indices?
```julia
for I in 1:5
@show value(x[I])
end
```

I tried this but am not getting it rightly.
This is the output I get when I run the code
value(w[I]) = 0.0
value(w[I]) = 0.0
value(w[I]) = 0.0
value(w[I]) = 0.0
value(w[I]) = 0.0
I want it to display as w1, w2, w3 …w5.
Your help will be greatly appreciated please.

I also want to write the codes below using a for loop.
Kindly help me out.
# Rewrite using a for loop
@constraint(model, X^2 + y^2 - d[1]-2X-2y \<= -2)
@constraint(model, X^2 + y^2 - d[2]-2X-8y \<= -17)
@constraint(model, X^2 + y^2 - d[3]-8X-8y \<= -32)

To interpolate the value of `i` into the string.
