How do I stop reading a line when I encounter a whitespace?

Question

I'm opening a file and reading it using getline(x,y) currently but I want to stop reading the line when I encounter a whitespace and then continue reading from there. Thanks

Answer 1

Formatted input will stop at white space:

std::string str;
while( file >> str)
    std::cout << str << std::endl;

Maybe instead you are looking for isspace( int ch) method:

#include <cctype>

if ( isspace( string.at(i)))
    // ... stop

Answer 2

因此，您可能希望从文件中读取每个字符，并使用if语句将其等于whitespace ，因此请看一下函数getc 。
