#include<iostream>

        int max,min,index;
        int i=1;
        int count=0;
        
        max=a>b?a:b;
        min=a<b?a:b;
        
        while(true)
        {
            cout<<++count<<endl;
            for(;i<=min;i++)
            {
                if(min%i==0)
                    {
                        index=min/i;
                        break;
                    }
            }
            
            if(max%index==0)
                break;
        }

int main()

    cout<<f(21,9)<<endl;

}

这是一个求最大a,b的最大公约数,那个while()死循环怎么解决啊?我没发现有错啊

cout是我发现while()是死循环的时候加的，用来验证while()是死循环的

是 count
