![]() ![]() ![]() You can omit the curlies if they contain anycodings_perl a simple scalar ($NAME). Assigning to array changes the length of the array array, hence you can destroy (or clear) all values of the array between the last element and the newly assigned position. As can be seen from the results output, the array elements are only four, but the size of the array 51. The array is used to store the list of values and each object of the list is termed as an element. array is the subscript of the last element of the array (which is one less than the length of the array, since arrays start from zero). So, if $messages contains a reference to anycodings_perl an array, the following will get its anycodings_perl size. In Perl, array is a special type of variable. If you have a reference to an array, anycodings_perl you'd use the following to get its size: # In scalar context array (1,2,3) print 'Size: ',scalar array,' ' The value returned will always be the physical size of the array, not the number of valid elements. If you have the name of an array, you'd anycodings_perl use the following to get its size: # In scalar context The size of an array in Perl can be determined using the scalar context on the array - the returned value will be the number of elements in the array. ![]() When you have a reference to a variable anycodings_perl instead of a variable name, you simply anycodings_perl replace the name in the syntax you want anycodings_perl to use with a block that evaluate to the anycodings_perl reference.
