I mean that you could use getline to fetch an entire line, and then use atoi to pull out an integer. However if you feed it a string like [1,2,+,3,-,4,5] it will simply return '0'.

| Jul 28, 2014 at 5:32 | comment | added | Ashhar Hasan | Also how exactly does atoi() function. Suppose I have a string like [1,2,+,3,-,4,5]. How does atoi() process the string? (PS: I actually need this for another one of my programs.) | |
| Jul 28, 2014 at 5:30 | comment | added | Ashhar Hasan | Thanks a lot. I never really pondered enough to notice that all primes except two are odd. About scanf, do you mean to say that I should use something like gets() to read in the input as a string and then process it? And do for loops and while loops have any major difference in functionality that I should know of? WHITESPACES. | |

for (int lines=40; lines; --lines) putchar('\n'); really? Otherwise +1
