分不清楚continue和break时接下去该算谁，求清楚解析

Question

#include<stdio.h> void main() { int a[4][4]={{1,2,-3,-4},{0,-12,-13,14},{-21,22,0,-24},{-31,32,-33,0}}; int i,j,s=0; for(i=0;i<4;i++) { for(j=0;j<4;j++) { if(a[i][j]<0) continue; if(a[i][j]==0) break; s+=a[i][j]; } } printf("%d\n",s); }

Answer 1

break是结束整个循环体，continue是结束单次循环

break跳出的是i的那层循环，continue跳出的是j的那层循环
