下面是说明basic_istream::get()的程序

程序1:

#include <bits/stdc++.h> 
using namespace std; 
  
// Driver Code 
int main() 
{ 
    // Declare string stream 
    istringstream gfg("GeeksforGeeks"); 
  
    // Here we get H 
    char a = gfg.get(); 
    cout << "First character is:"
         << a << endl; 
  
    char b; 
    // Here we got e 
    gfg.get(b); 
    cout << "After reading:" << a 
         << " We got " << b << endl; 
  
    return 0; 
}

输出：

First character is:G
After reading:G We got e

程序2:

// C++ code for basic_istream::get() 
#include <bits/stdc++.h> 
using namespace std; 
  
// Driver Code 
int main() 
{ 
    // Declare string stream 
    istringstream gfg("Computer"); 
  
    // Here we get C 
    char a = gfg.get(); 
    cout << "First character is:"
         << a << endl; 
  
    char b; 
    // Here we got o 
    gfg.get(b); 
    cout << "After reading:" << a 
         << " We got " << b << endl; 
  
    char c; 
    // Here we got m 
    gfg.get(c); 
    cout << "Now we got:"
         << c << endl; 
  
    return 0; 
}
