代码本-数组入门

AcWing 数组的部分 #include<cstdio> int main() { char t; scanf("%c",&t); double q[12][12]; // 初始化后全部读入 for (int i = 0;i < 12; i ++ ) for (int j = 0;j < 12; j ++ ) scanf("%lf",&q[i][j]); double s = 0, c = 0; for (int i = 1; i <= 5; i ++ ) for (int j = 0;j < #(i - 1)#；j ++ ) { s += q[i][j]; c += 1; } for (int i = 6; i <= 10 ;i ++ ) for (int j = 0; j <= #(10 - i)#; j ++ ) { s += q[i][j]; c += 1; } if ( t == 'S') printf ("%.1lf\n",s); else printf("%.1lf\n", s / c ); return 0; }
