Multiple for loops

if we use multiple for loops like in pattern printing questions

multiple for loops inside a for loop;; then please tell me which for loop will compile first and which for loop will compile last, from the point of compiler

please explain in proper detailed answer with the help of example,

as its very important to know the execution style of my program

Let’s say you have

          for(int i=0;i<n;i++){
                 for(int j=0;j<n;j++){

                 }

                 for(int k=0;k<n;k++){
                        
                 }
          }

Now first the loop for i starts , Now for every i, loop for j runs from 0 to n, and then a loop for k runs from 0 to n. This is the order in which they are executed.
