输入多个字符串C++

Question

下面的代码尝试输入多个字符串与空白，然后我需要做他们之间的比较。我面临的问题是，它不能输入超出第一个字符串的字符串。我想这是输入缓冲区中的“输入”，导致这种行为，即跳过字符串的进一步输入。任何建议如何克服这一点？

编辑：清除和冲洗我曾尝试，但仍然同样的问题。 我需要实现C风格的字符串函数，所以不能使用字符串类，strcmp等函数必须由我来实现，而不是使用库函数。

int main() 
    { 
     char s[100]; 
     char s1[100]; 
     char s2[100]; 
     char* sub; 

     struct countSpaces cs; 



cout << "Enter a String : "; 
cin.get(s, 100); 
std::cin.clear(); 
cs=count(s); 

cout << s << " contains " << cs.letters << " letters and " << cs.spaces << " spaces" << endl; 
cout << "Length of " << s << " is " << strlen(s) << endl; 

cout << "Enter First String : "; 
cin.get(s1, 100); 
std::cin.clear(); 
cout << "Enter second String : "; 
cin.get(s2, 100); 
std::cin.clear(); 

     if(strcmp(s1,s2)) 
     cout << s1 << " is equal to " << s2 << endl; 
     else 
     cout << s1 << " is not equal to " << s2 << endl; 


     return 0; 
     } 

输出：

$ ./String 
Enter a String : Herbert Schildt 
Herbert Schildt contains 14 letters and 1 spaces 
Length of Herbert Schildt is 15 
Enter First String : Enter second String : is not equal to

#include <iostream> 
#include <string> 

using namespace std; 

int main() 
{ 
    string s1 = ""; 
    string s2 = ""; 

    cout << "Enter first string > "; 

    getline(cin, s1); 

    cout << "Enter second string > "; 

    getline(cin, s2); 

    if(strcmp(s1,s2)) 
     cout << s1 << " is equal to " << s2 << endl; 
    else 
     cout << s1 << " is not equal to " << s2 << endl; 

    // copy string s1 into C-String str 
    char * str = new char [s1.length()+1]; 
    std::strcpy (str, s1.c_str()); 

    return 0; 
}

std::cin.ignore(100,'\n');的伎俩。
