I have a problem with the implicit LIBRARY_PATH modification of g++ between two versions ( g++ -v gives this info). I set the LIBRARY_PATH to a single local directory where I have custom libraries. However, it turned out that only one version of the g++ (let's call it version A) correctly linked, the other (version B) linked to the system-default, which was not desired. Apparently, the order of directories was mixed up and my specification was not properly respected. It is a similar issue to LIBRARY_PATH not used before /usr/lib anymore in gcc 4.2 and later? although not with these versions.

第一种方式：import syssys.stdout.write("请输入：\n")while True: line = sys.stdin.readline() if line == "\n": break else: print(line)第二种方式： import syss_line = sys.stdin.readline()i_line = input()print(len(s_line))print(len(i_line))# 注意sys.stdin。readline（），输入全部获取后，末尾添加“\n，input会把”\n“忽略 来源： https://www.cnblogs.com/byh7595/p/11966318.html

while(getline (&line, &line_size, f) != -1){} I'm using this function to read line line. But i want to know when i'm reading a blank line. Can someone help? none so as H2CO3 already mentioned you can use the line length for this: while (getline (&line, &line_size, f) != -1) { if (strlen(line) == 1) { printf("H2CO3 spotted a blank line\n"); } /* or alternatively */ if ('\n' == line[0]) { printf("Ed Heal also spotted the blank line\n"); } .. } You need to define blank line. Also, because "The getline function reads an entire line from a stream, up to and including the next newline character." I

I have this code: fn main() { let mut stdin = io::stdin(); let input = &mut String::new(); loop { input.clear(); print!("Your age: "); stdin.read_line(input); print!("{}", input); } } So when I input something, the programs returns "Your age:" plus my input. But when I run the program I don't want to write the input in a new line. To do something like that in Python, I can write: var = input("Your age: ") How can I avoid going to a new line? I'm sure it's simple but I really can't realize how to do that, I tried a lot of different stuff... antoyo You need to flush stdout before reading the

I have a UITableView (which happens to have a UISearchBar ) and can't seem to figure out how to get rid of the white/gray border above it. I need to have seamless black between the UISearchBar and the black above it. I have tried hiding the UISearchBar to see if that had anything to do with it, but the line still appeared. Any ideas? In my case it helped to set: searchBar.clipsToBounds = YES; You have to customise the UISearchBar background to match according to your requirements., take a look at this tutorial. You should try this, by which you can set the color of cell borders and if you want
