Think of it this way, if you would simply give scanf the variable a without the &, it will be passed to it by-value, which means scanf will not be able to set its value for you to see. Passing it by-reference (using & actually passes a pointer to a) allows scanf to set it so that the calling functions will see the change too ...Thu, 16 Apr 2026 23:16:00 GMThttps://stackoverflow.com/questions/79723838/how-do-i-properly-use-scanf-and-what-are-its-limitsThanks for asking.

The value that was output in your code is just the value that was in the uninitialized i variable - the scanf call didn't change it.Tue, 21 Apr 2026 09:48:00 GMThttps://stackoverflow.com/questions/10469643/what-does-the-scanf-function-returnscanf On success, the function returns the number of items successfully read. This count can match the expected number of readings or fewer, even zero, if a matching failure happens. In the case of an input failure before any data could be successfully read, EOF is returned.Wed, 22 Apr 2026 14:04:00 GMThttps://stackoverflow.com/questions/10597606/why-does-scanf-requireI want to read a number from stdin. I don't understand why scanf requires the use of & before the name of my variable: int i; scanf("%d", &i); Why does scanf need the address of the variable?Wed, 22 Apr 2026 17:03:00 GMThttps://stackoverflow.com/questions/13542055/how-to-do-scanf-for-single-char-in-cThe %c conversion specifier won't automatically skip any leading whitespace, so if there's a stray newline in the input stream (from a previous entry, for example) the scanf call will consume it immediately. One way around the problem is to put a blank space before the conversion specifier in the format string:Wed, 22 Apr 2026 13:21:00 GMThttps://stackoverflow.com/questions/75672496/the-times-when-we-have-to-use-scanf-n-and-scanfc1 In C, when we use a scanf("%s") or scanf("%c") before a scanf("%s") or scanf("%[^\n]"), while giving in the input, there will be an extra '\n' at the end of the first input and that will be passed into the second input and mess up the input stream. I've tried these codes in two different systems with the same gcc compiler as far as I know.Sun, 19 Apr 2026 00:25:00 GMThttps://stackoverflow.com/questions/40038538/how-does-scanf-n-str-work-in-c-programmingThis scanf format string consists of two parts: a space character, which skips space characters (' ', '\t', '\n', etcetera) in the input, and the %[^\n] conversion specification, which matches a string of all characters not equal to the new line character ('\n') and stores it (plus a terminating '\0' character) in str. Note however that if the input (after the leading spaces, and before the ...Mon, 20 Apr 2026 13:02:00 GMThttps://stackoverflow.com/questions/35103745/read-a-string-as-an-input-using-scanfRead a string as an input using scanf Asked 10 years, 2 months ago Modified 6 years, 4 months ago Viewed 116k timesWed, 22 Apr 2026 15:02:00 GMThttps://pt.stackoverflow.com/questions/321827/por-que-n%c3%a3o-precisa-do-no-scanfVocê está passando uma variável para a função não porque precisa mandar um valor para a função, de fato a variável pode nem ter um valor válido, para o scanf() isto não importa, a questão é que no final da execução do scanf() o valor digitado pelo usuário precisa ser colocado em algum lugar e ele coloca justamente na variável ...Fri, 03 Apr 2026 03:57:00 GMT
