Above output shows scanf has terminated the scan once space has been found in the buffer. We often require to take input of full name, address and other fields where we have spaces inside the input. To deal with these situation we can scan the entire line of string and terminate the ...
"Test 2" refers to the average time of scanning a value, which contains multiple values in their text representations, separated by spaces. The time used for creating any state needed for the scanner is not included. This test is called "repeated" in the benchmark sources. The string test...
Whitespace character:the function will read and ignore any whitespace characters (this includes blank spaces and the newline and tab characters) which are encountered before the next non-whitespace character. This includes any quantity of whitespace characters, or none. Non-whitespace character, except...
I removed the spaces between '-') I need to change my scanf() to n = sscanf (buffer, "%d%*c%d", &from, &to); /*change from %s to %c */ Can somebody please provide me with one scanf() statement that can handle both spaces and non spaces between my values. The man page on...
edit: Still, if you take the creating of the string outside the loop, with lets say std::stringstream and sprintf(), and output just the strings, cout will obviously still beat printf. I tested what you pasted, and added spaces to the cout line, just to make it identical (even more...
Frankly I see this as a terrible flaw in C's input functions, they should ALWAYS wait, no matter what... others will have varying opinions. There are several strategies for fixing the problem... The best one seems to be to treat all input as strings then sscanf() the val...

Usegets()inscanfto Get User Input With Spaces in C Thechar *gets(char *str)function included in the C library will read a line from the standard input (stdin) and save it in the string referred to bystr. It halts either when the newline character is read or when the end of the ...
这是可以使用一个库函数fflush(stdin)来清除缓冲。不过貌似雨中飞燕大姐说这个用法是非标准的。K&R,只是说行为没有定义,但我们可以使用while((c=getchar())!='\n'&&c!=EOF);同样可以清除后面的垃圾 scanf的格式匹配还是比较简单,一定要记住的就是普通变量一定要加上&,否则编译器无法检测错误,但运行肯定会段错误...
