a shell variable is capable enough to hold single or multiple values.shell supports a different type of variable called "array variable" to store multiple values at the same time with giving a single name to variable.
declare -a [ ARRAY_NAME ]
Array_Name [ Index ] = Value
declare -a myarray
myarray[0] = 'Virtualhax Inc.'
myarray[1] = 'Veewom Technology'
myarray[2] = 'Quizer Studio'
echo ${myarray[0]}
#Output
#Virtualhax Inc.
