• 找出100~9gggg之问的回文数。用C语言完成。

以下是用C语言实现的代码，可以找出100~9gggg之间的回文数：

#include <stdio.h>

int isPalindrome(int num) {
    int reversed = 0, original = num;
    while (num > 0) {
        reversed = reversed * 10 + num % 10;
        num /= 10;
    }
    return reversed == original;
}

int main() {
    int start = 100, end = 99999;
    for (int i = start; i <= end; i++) {
        if (isPalindrome(i)) {
            printf("%d ", i);
        }
    }
    return 0;
}

该程序首先定义了一个名为`isPalindrome`的函数，该函数接受一个整数作为参数，并返回一个布尔值，表示该整数是否为回文数。该函数的实现方式是将该整数翻转并与原始整数进行比较。

然后，程序在`main`函数中使用循环遍历100~9gggg之间的所有整数，并对每个整数调用`isPalindrome`函数进行判断。如果该整数是回文数，则将其输出到控制台。

注意，由于题目中的范围是100~9gggg，其中gggg部分未知，因此程序中使用了变量`end`来代表范围的上限。在实际使用中，需要根据具体情况进行调整。

创建一个程序， 要求能够打印类似下面的结果（ 直到每行 25 个字符时为止） ： 1. G 2. GG 3. GGG 4. GGGG 5. GGGGG 6. GGGGGG

以下是 Python 3 的程序实现：

i = 1
while True:
    line = "G" * i  # 生成相应数量的 G
    print(f"{i}. {line}", end=" ")  # 输出当前行
    if len(line) >= 25:  # 判断是否达到 25 个字符
        break
    i += 1  # 行数加一

输出：

1. G 2. GG 3. GGG 4. GGGG 5. GGGGG 6. GGGGGG 7. GGGGGGG 8. GGGGGGGG 9. GGGGGGGGG 10. GGGGGGGGGG 11. GGGGGGGGGGG 12. GGGGGGGGGGGG 13. GGGGGGGGGGGGG 14. GGGGGGGGGGGGGG 15. GGGGGGGGGGGGGGG 16.
