4.10. Lua loop nesting

4.10.1. Grammar #

In the Lua programming language for loop nested syntax format:

for init,max/min value, increment do for init,max/min value, increment do statements end statements end 

In the Lua programming language while loop nested syntax format:

while(condition) do while(condition) do statements end statements end 

In the Lua programming language repeat...until loop nested syntax format:

repeat statements repeat statements until( condition ) until( condition ) 

In addition to the same type of loop nesting above, we can also use different loop types to nest, such as for nesting in the loop body while cycle.

4.10.2. Example #

The following example uses the for loop nesting:

j =2 for i=2,10 do for j=2,(i/j) , 2 do if(not(i%j)) then break end if(j > (i/j))then print("The value of i is：",i) end end end 

The value of i is: 8 The value of i is: 9 The value of i is: 10
