put 函数

#include<iostream>using namespace std;int main(){char *a = "BASIC";for (int i = 4; i >= 0; i--){cout.put(*(a + i));}cout.put('\n');system("pause");return 0;}
输出结果:



putchar 函数

#include<iostream>using namespace std;int main(){char *a = "BASIC";for (int i = 4; i >= 0; i--){putchar(*(a + i));}putchar('\n');system("pause");return 0;}
输出结果:





getline 函数

#include<iostream>using namespace std;int main(){char ch[20];cout << "enter a sentence:" << endl;cin >> ch;cout << "The string read with cin is; " << ch << endl;cin.getline(ch, 20, '/');cout << "The second  part is; " << ch << endl;cin.getline(ch, 20);cout << "The third part is; " << ch << endl;system("pause");    return 0;}

输出结果:


#include<iostream>using namespace std;int main(){float grade;cout << "enter grade:";while (cin >> grade){if(grade >= 85){cout << grade << "GOOD!" << endl;}if(grade < 60){cout << grade << "FAIL!" << endl;}cout << "enter grade:";}cout << "the end" << endl;system("pause");return 0;}
