Question

这个visual c++ 6.0程序编译时没有出错，但运行时程序中止，求解

#include<iostream>
using namespace std;
int g(int a,int b){int r;r=a%b;if(r=0) return b;else return g(b,r);}

int main()
{long int a,b,p,q,s;
cout<<"To get GCD and LCM"<<endl<<"please enter a,b:";
cin>>a>>b;
for(;a<=0||b<=0;){cout<<"please enter a,b>0:";cin>>a>>b;}
if(b>a) s=a,a=b,b=s;p=g(a,b);
q=a*b/p;
cout<<"(a,b)="<<p<<endl;
cout<<"[a,b]="<<q<<endl;
return 0;}

Answer 1

int g(int a,int b)
{
	int r;
	r=a%b;
	if(r==0) //原代码r=0是赋值,判断相等 用 ==
		return b;
	else 
		return g(b,r);
}
