为什么我会出现分段错误?
问题描述：
我应该递归打印两个数字的乘积.这是我的代码:
I am supposed to print product of two numbers recursively. this is my code :
#include<stdio.h>
int prod(int num1,int num2)
{
if(num2=0)
return num1;
prod(num1+num1,num2-1);
}
int main()
{
int n1,n2;
printf("Enter two numbers to find their product:\n");
scanf("%d" ,&n1);
scanf("%d" ,&n2);
printf("Product of %d and %d is %d",n1,n2,prod(n1,n2));
return 0;
}
这是一个简单的代码，但为什么我会遇到分段错误?请帮忙.
This is a simple code but why am i getting segmentation fault? please help.
答
两个问题:
- 您需要比较，而不是赋值运算符.
- 您需要返回递归调用.
见下文:
int prod(int num1,int num2)
{
if(num2 == 0)
return num1;
return prod(num1+num1,num2-1);
}
