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 ...
"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. ...
In this case, a parser is constructed, and a value (123) is parsed. This test is called "single" in the benchmark sources. "Test 2" refers to the average time of parsing a value from a string containing multiple string representations separated by spaces. The time used for constructing ...

C - Using scanf to skip N white spaces, In your question the part with integer variables is missing. scanf () and sscanf () want to skip white spaces in general. One white space in the formatting is enough to specify it. Because you only care about the two ints, you don't need ...
still accommodate the precision required. For example "%d" with a 7 passed in will simply become "7", however "%3d" specifies a minimum width of 3 so passing it 7 will result in " 7" (two spaces followed by a 7). Flags can be used to specify how the number is adjusted and ...
scanf("%c",&c); 如果这写的话,变量c放的一定是回车。 如果想实现这种输入,可以在两个语句之间加入一个getchar(),他可以吃掉这个回车, 也可用scanf("%d %c",&h,&c);来做,再输入数字后加一个空格。就可以了 但千万别用scanf("%d\n",&h)!!!k&r说的十分清楚,任何非格式化的字符都需要完全匹配。
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...
