c语言错题

c 错题#includeiostreamusing namespace std;intbitCount(intx){inty0;for(;x0;){yx1;x1;}returny;}intmain(){// 请在此输入您的代码inti,n,m,j;scanf(%d,n);inta[n];for(i0;in;i){scanf(%d,a[i]);}scanf(%d,m);for(j0;jm;j){for(i0;in;i){a[i]a[i]*bitCount(a[i]);}}for(i0;in;i){printf(%d ,a[i]);}return0;}在下面这一块犯的错误是先命名后输入scanfinti,n,m,j;inta[n];scanf(%d,n);改正先scanf 后命名inti,n,m,j;scanf(%d,n);inta[n];
