读入两个 int 范围内的整数, 并将这两个整数分别输出,每行一个。
#include <iostream> using namespace std; int readint() { int num = 0; // 存储读取到的整数 int negative = 0; // 负数标识 char c; // 存储当前读取到的字符 c = cin.get(); while ((c < '0' || c > '9') && c != '-') c = _____(1)_______; if (c == '-') negative = 1; else _____(2)_______; c = cin.get(); while ( _____(3)_______) { _____(4)_______ c = cin.get(); } if (negative == 1) _____(5)______ return num; } int main() { int a, b; a = readint(); b = readint(); cout << a << endl << b << endl; return 0; }
