Looping over arrays, printing both index and value

Question

I want to do something like this:

foo=( )
foo[0]=\"bar\"
foo[35]=\"baz\"
for((i=0;i<${#foo[@]};i++))
do
    echo \"$i: ${foo[$i]}\"
done
# Output:
# 0: ba

users=("kamal" "jamal" "rahim" "karim" "sadia")
index=()
t=-1

for i in ${users[@]}; do
  t=$(( t + 1 ))
  if [ $t -eq 0 ]; then
    for j in ${!users[@]}; do
      index[$j]=$j
    done
  fi
  echo "${index[$t]} is $i"
done
