No

To see what conditions cause goto, you can use do while etc. instead. That condition is usually while (condition)

See the logical structure and then change
Goto for looping is changed with while for
But in special cases, the goto method is better, such as read value loop

Add BREAK or CONTINUE with a loop. The key to always being able to do this is to understand the procedures.

GOTO changed to loop,
This seems to be very problematic ...

goto is a statement jump,
There is no way for loops to achieve jumps ...
Even break can only end the loop,
It's impossible to skip the statements after the loop ...

However, the specific situation is analyzed specifically,
In some special cases,
It is possible to eliminate goto ...

Can only be changed to recursion

Is this a problem in itself? ? ?

Basically there is no need to use goto to achieve, at least I have not encountered

For simple goto situations, it can be easily changed to a while loop, such as:
A: ......

if (B)
  goto A
This can be changed to do {……} while (B)
But if there is an unfinished loop between the A and if statements (if there is {but not} in a loop, or {not}}, then it must be carefully analyzed and it is difficult to find a general method

Generally can be modified while while if condition
