int fac (int n) { if (n < 0) return -1; //n must be positive if (n <= 1) return 1; return n * fac (n-1); } n <= 1 will be the condition to exit our recursion. Let's say n is 3. We get 3 * fac (2), but 2 is also bigger than one, so we get 3 * 2 ...

Here you will get program to findfactorialof large number in C and C++. Factorial of big numbers contain so many digits. For example factorial of 100 has almost 158 digits. So there is no data type available to store such a long value. But we can find factorial for large numbers using ...

输出结果为: 代码语言:txt 复制 The factorial of 5 is 120 在这个示例中,factorial函数使用递归的方式计算阶乘。当n为0时,返回1作为终止条件。否则,将n与n-1的阶乘相乘,直到n为0。 对于无法计算阶乘的情况,可以考虑输出一个错误提示或返回一个特定的错误码,以便在程序中进行处理。相关搜索: ...
