当我通过字符串从文件字符串中读取时,>> operation获取第一个字符串,但它以"i"开头.假设第一个字符串是"street",而不是"istreet".
其他字符串也没关系.我尝试了不同的txt文件.结果是一样的.第一个字符串以"i"开头.问题是什么?
这是我的代码:
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
int cube(int x){ return (x*x*x);}
int main(){
int maxChar;
int lineLength=0;
int cost=0;
cout<<"Enter the max char per line... : ";
cin>>maxChar;
cout<<endl<<"Max char per line is : "<<maxChar<<endl;
fstream inFile("bla.txt",ios::in);
if (!inFile) {
cerr << "Unable to open file datafile.txt";
exit(1); // call system to stop
}
while(!inFile.eof()) {
string word;
inFile >> word;
cout<<word<<endl;
cout<<word.length()<<endl;
if(word.length()+lineLength<=maxChar){
lineLength +=(word.length()+1);
}
else {
cost+=cube(maxChar-(lineLength-1));
lineLength=(word.length()+1); …Run Code Online (Sandbox Code Playgroud) 这是我的代码:

my @headers = split /,/, $h;

} else {
print "ok\n";
}
}
return 1;

在我的第一个单元测试中,我将一个字符串传递给 $h,该字符串与 $expected 匹配。然后我有一个单元测试,它确保函数在传递不匹配的字符串时失败。这两个测试的行为符合预期。
