Does C language allow recursive calling of functions?

Does the C language allow recursive calls of functions?

Yes. The process in which a function in C language directly or indirectly calls itself is called recursion.

1. Two necessary conditions for recursion

1. There are restrictions. When this condition is met, recursion will not Continue again.

2. Each recursive call gets closer and closer to this limit.

2. Classic recursion question-finding the nth Fibonacci number

#include <stdio.h>
#include <stdlib.h>
int fibonacci(int n)
{
	if(n <= 2)
	{
		return 1;
	}
	else
	{
	    return fibonacci(n - 1) + fibonacci(n - 2);
    }
}
int main()
{
	int n;
	printf("请输入你想输出第几项的斐波那契数：\n");
	scanf("%d", &n);
	printf("%d\n", fibonacci(n));
	system("pause");
	return 0;
}
