Hierarchy of nested "for" loops

for (x=1; x<100; x++)
{
....
for (i=1; i<10; i++)
{....}
for (j=1; j<10; j++)
{...}
...
}

In the i loop we obtain a result that must be introduced in the j loop. I thought that it would do firstly the loop for i and then the loop for j, but it seems like if it were doing both loops at the same time, because when we cancell the j loop the result for the i one is correct, but with both working simoultaneously the result for i is perturbed by the second loop. Am I correct?

Thak you very much for your time and for your help!

The braces {} should tell you how your loops will behave.

My question is, which loop does it run before, "i" or "j", or they run simoultaneouslly? because they are at the same level within de "x" loop.
