If (b % j==0) {b -; break; }

CodePudding user response:

Could you tell me why is this,,,

CodePudding user response:

If (b % j==0) this condition does not need to add a curly braces, so break, not always be executed conditions didn't also met then break, lead to the value of b will not change, the infinite loop

CodePudding user response:

After the for loop, if else statements with curly braces, even behind with only one line of code, form good habits of code
