C++语言 如何证明1到1000的3n+1猜想，要用到双循环结构，求大神帮助

#include

using namespace std;
int main()

{

for(int n = 1; n <= 1000; n++)
for(int m=1;m<=1000;m++) {
int count = 0;

while (n != 1)

{

if (n % 2 == 0)

n /= 2;

else

n = (3 * n + 1) / 2;if(m=1000,n=1000)break;

count++;

}
cout << "m="<<m<<n << ": " << count << endl;
}
}

 #include<iostream>  
using namespace std;
int main()

for(int n = 1; n <= 1000; n++) {
    int count = 0;  
    while (n != 1)

            n /= 2;  
        else  
            n = (3 * n + 1) / 2;  
        count++;  
    } 
        cout << n << ": " << count << endl;
}
