scanf

问题 I'm new to the c language and used java before, so I'm not so familiar with some things... I want to read an indefinite number of integer until there's a new line. I know, that new line is ⁄n and I already have a code, so the integer are read until you type in a letter, but it doesn't stop, if there's a new line. #include <stdio.h> int main() { int i, numberOfNumbs=0,total=0,value, valsRead; float average; valsRead = scanf("%d",&value); while(valsRead>0) { numberOfNumbs++; total +=value;

问题 I am taking multiple integer inputs using scanf and saving it in an array while(scanf("%d",&array[i++])==1); The input integers are separated by white spaces for example: 12 345 132 123 I read this solution in another post. But the problem is the while loop is not terminating. What's the problem with this statement? 回答1: OP is using the Enter or '\n' to indicate the end of input and spaces as number delimiters. scanf("%d",... does not distinguish between these white-spaces. In OP's while()

问题 I am currently trying to parse UnicodeData.txt with this format: ftp://ftp.unicode.org/Public/3.0-Update/UnicodeData-3.0.0.html However, I am hitting a problem in that when I try to read, say a line like the following. something;123D;;LINE TABULATION; I try to get the data from the fields by code such as the following. The problem is that fields[3] is not getting filled in, and scanf is returning 2. in is the current line. char fields[4][256]; sscanf(in, "%[^;];%[^;];%[^;];%[^;];%[^;];",

问题 This question already has answers here : scanf() leaves the new line char in the buffer (4 answers) Closed 3 years ago . I have two questions: why only when i do space in "%d " --> scanf("%d ", &num); it works? I tried fflush(stdin) \ _flushall() between the scnaf and the gets and it doesn't works, it skips the gets. When I do the space, it first does scanf then the gets and after that it print the number and print the string. void main() { char ch, str[10]; int num; printf("Enter your number

问题 I am creating a mailing label generator for school and am having an issue with a few problems. My program is to take the full name, address, city, state, and zip code for individuals from 0 to 10. When running my program I am having two major problems. The for loop skips the full name "safergets()" and moves on to the address safergets. I moved on to see if everything else works, but my verification for the zip code would not work correctly. I added a printf to see if the input was the same
