Is it allowed to change the counter variable within a for loop in ANSI C? Example: #include <stdio.h> #include <stdlib.h> int main() { int i,a; for (i=1;i<5;++i){ scanf("%d", &a); if (a%2==0) printf("value is correct: 2%d\n",a); else { printf("try again\n"); i--; } } return 0; }

Yeah that's fine.

>>10932 You should really try searching for the solutions to your problems before making a thread. You should also look in the catalog first for threads that may already cover your topic. This would have been more appropriate in the Beginner's General: https://lainchan.org/%CE%BB/res/5683.html Now that the thread's here, I suppose it should just be a general C thread.

>>10938 Yes, but you already had an example you could have tested yourself. C has a standard, which is really a requirement for any serious language, and if you haven't read it yet I suggest you do. It will really help you as you go on.

>>10932 The i variable is being used for two numbers, iterations and successes. You're better off using a while loop and a meaningful variable name as a counter. break statement to exit the loop.
