Re:这个程序有以下毛病,请大虾们帮忙指正,本人不胜感激!!!E:\周华健\4545\4545.cpp(21) : error C2106: '=' : left operand must be l-valueIn Reply To:这个程序有以下毛病,请大虾们帮忙指正,本人不胜感激!!!E:\周华健\4545\4545.cpp(21) : error C2106: '=' : left operand must be l-value Posted by:90401304 at 2004-12-22 20:04:16 其中你写sp=sp??我好疑惑。
貌似你中间在用冒泡排序,但if你错了。
if(*sp+k<*sp+k+1){
tem=sp+k;
sp+k=sp+k+1;
sp+k+1=tem;
} }
粗看,就知道错了,应该*(sp+k)<*(sp+k+1)
下面也应该改掉:
tem=*(sp+k);
*(sp+k)=*(sp+k+1);
*(sp+k+1)=tem;
