hello大家好,我是文宇。
今天是速通c++的最后一天。(周日是愉快的玩耍,学个毛线)
今天是一些用循环写的骚操作(娱乐)
正文
以下是一些在C++中使用循环进行的有趣和骚操作的例子:
- 打印三角形:
int n = 5;
for (int i = 0; i < n; i++) {
for (int j = 0; j <= i; j++) {
cout << "*";
}
cout << endl;
}
输出:
*
**
***
****
*****
- 反向打印字符串:
string str = "Hello World";
for (int i = str.length() - 1; i >= 0; i--) {
cout << str[i];
}
输出:
dlroW olleH
- 九九乘法表:
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
cout << j << " * " << i << " = " << i*j << " ";
}
cout << endl;
}
输出:
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
- 打印菱形:
int n = 5;
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= n - i; j++) {
cout << " ";
}
for (int k = 1; k <= 2*i - 1; k++) {
cout << "*";
}
cout << endl;
}
for (int i = n - 1; i >= 1; i--) {
for (int j = 1; j <= n - i; j++) {
cout << " ";
}
for (int k = 1; k <= 2*i - 1; k++) {
cout << "*";
}
cout << endl;
}
输出:
*
***
*****
*******
*********
*******
*****
***
*
这些骚操作只是给你一些灵感,你可以根据自己的需求和创意使用循环进行更多有趣的操作。请记住,代码的骚操作并不一定是实用或有效的,但它们可以帮助你更好地了解和掌握C++的循环语法和逻辑。
