问题描述
我从文档中提取了单词,并将所有单词打印在屏幕上,但是在每个单词打印之后,都有一个空白行.如何避免读取新行或将新行添加到字符串中?
I get the words from my document extracted and all are printed on screen, but after each word printed there is a blank line. How can I avoid reading or adding this new line to the string?
int main(void) {
FILE *f;
f = ("words", "r");
char string[100];
while (fgets(string, 100, f)) {
printf("%s", string);
}
}
此代码不是复制粘贴的,因此我本可以忘记一些小片段,但应该可以工作.在words.txt中,我每行有一个单词.我的程序将它们全部打印到屏幕上,但是在每个单词之后添加新行.我不希望它添加新行或空格.因此,如果txt的一行上有 Hello
,而下一行是 Bye
,则我希望它打印 HelloBye
.最终程序的目的不是打印字符串,而是将字符串用于其他用途,因此我确实需要一个字符串,该字符串的末尾或换行符必须是不带空格的文本.
This code was not copy pasted, so I could have forgotten tiny pieces but should work. In words.txt I have one word on each line. My program prints them all to screen, but adds a new line after each word. I do not want it to add a new line, or a space. So if the txt had Hello
on one line and Bye
on the next line, I want it to print HelloBye
. The objective of the final program will not be to print the string, it will be to use the string for something else, so I do need a string that only has the text without spaces at the end or new lines.
推荐答案
尝试一下.
int main()
{
FILE *f;
f = ("words", "r");
char string[100];
while (fgets(string, 100, f))
{
char * message = strtok(string, "\n");
printf("%s", message);
}
}
strtok
将字符串标记为您的消息
, \ n
. fgets
将捕获 \ n
令牌
strtok
tokenizes the string into your message
, \n
. fgets
will capture the \n
token
