{
for(j=i+1;j<n;j++)
{
if (score[i]<score[j])
{temp1=score[i];score[i]=score[j];score[j]=temp1;
temp2=num[i];num[i]=num[j];num[j]=temp2

姓名交换怎么写

Answer 1

用strcpy进行字符串复制交换

char t[100] = {0};
if (score[i]<score[j])
{temp1=score[i];score[i]=score[j];score[j]=temp1;
temp2=num[i];num[i]=num[j];num[j]=temp2;
strcpy(t,name[i]);
strcpy(name[i],name[j]);
strcpy(name[j],t);
}
