c++的break和continue的"标签用法"

#include <iostream>
int main(int argc, char* argv[])
{
std::cout << "[begin>" << std::endl;
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
if ((i + j) % 5 == 0)
{
std::cout << "continue i" << std::endl;
goto continuei;
}
if (i == 8 && j == 1)
{
std::cout << "break i" << std::endl;
goto breaki;
}
std::cout << i << ", " << j << std::endl;
}
continuei: continue;
breaki: break;
}

std::cout << "<end]" << std::endl;
}
