What are some few helpful tips on loops?

Question

Are there general helpful tips that someone can share on loops(Any language is okay since their functioning is similar). I already know how they work in general but still struggle with them in some areas. I noted this because I fail almost every loop related question on challenges. I'd appreciate a sort of simplified guide on how to look at loops in different perspectives.

Answer 2

the most common loop questions on sololearn are loops nested in other loops!I don think any course explains those.
int a=0;
for(int I=0;I<7;I++)
{
for(int v=0;v<5;v++)
{
a++;} }
To calculate how the work just do the number of times the outermost loop runs multiplied with the number of times the innermost loop runs I.e 7×5=35!
so you can guess a=35;
hope I helped
