习题1.18
编写程序，提示用户输入两个数并将这两个数范围内的每个数写到标准输出。
【解答】
while循环实现
1 #include <iostream> 2 using namespace std; 3 4 int main() 5 { 6 int v1, v2, low,up; 7 cout << "Enter tow numbers " << endl; 8 cin >> v1 >> v2; 9 if (v1 < v2) 10 { 11 low = v1; 12 up = v2; 13 } 14 else 15 { 16 low = v2; 17 up = v1; 18 } 19 cout << "Values of " << low << " to " << up << " inclusive are: " << endl; 20 while (up >= low) 21 cout << low++ << " "; 22 cout << endl; 23 return 0; 24 }
for循环实现
1 #include <iostream> 2 using namespace std; 3 4 int main() 5 { 6 int v1, v2, low,up; 7 cout << "Enter tow numbers " << endl; 8 cin >> v1 >> v2; 9 if (v1 < v2) 10 { 11 low = v1; 12 up = v2; 13 } 14 else 15 { 16 low = v2; 17 up = v1; 18 } 19 cout << "Values of " << low << " to " << up << " inclusive are: " << endl; 20 for (int val = low; val <= up; ++val) 21 cout << val << " "; 22 cout << endl; 23 return 0; 24 }
