C 递归函数调用概念

Question

/*Program to print all the numbers between a lower bound and a upper bound values*/     

#include<stdio.h>
#include<stdlib.h>
void recur(int a, int b);
int main(void)
{
    int x,y;
    printf("Enter the lower and upper bound values: \n");
    scanf("%d %d",&x,&y);
    void recur(x,y);
    return 0;
}
void recur(int a,int b)
{
    if(a<b)
    {
        printf("%d /n",a);
        a++;
        void recur(a,b);
    }
}

我得到的输出是:

Enter the lower and upper bound values:
    10
    50
    process returned 0.

语法或返回类型有什么问题吗？ 我刚刚开始学习 c.需要帮助

Answer 1

两者

void recur(x,y);
void recur(a,b);

声明函数(原型(prototype))。要调用它们，请将它们更改为

recur(x,y);
recur(a,b);
