New array can be created in two ways. First is to use '''array''' operator | New array can be created in two ways. First is to use '''array''' operator. <br> | ||
This statement will create empty array and assign reference to it to variable ''a''. | |||
<syntaxhighlight lang="c"> | |||
array a; | |||
</syntaxhighlight> | |||
You can then assign values to the array like this.<br> | |||
Please note arrays in NXSL are sparse, so you can have elements with nothing in between. | |||
<syntaxhighlight lang="c"> | <syntaxhighlight lang="c"> | ||
array a; | array a; | ||
a[1] = 1; | |||
a[2] = 2; | |||
a[260] = 260; | |||
println(a[1]); // will print 1 | |||
</syntaxhighlight> | </syntaxhighlight> | ||
Second way is to use %( ) construct to create array already populated with values.<br> | |||
This statement will create array with four elements at positions 0, 1, 2, and 3, and assign reference to this array to variable ''a''. | |||
<syntaxhighlight lang="c"> | <syntaxhighlight lang="c"> | ||
// no need to use "array a;" here, since we are creating it dirrectly | |||
a = %(1, 2, 3, 4); | a = %(1, 2, 3, 4); | ||
println(a[0]); // will actually print 1, since 1 is the 0th member | |||
</syntaxhighlight> | </syntaxhighlight> | ||
Array initialization can also be used directly in expressions, like this: | |||
