数据结构中数组的问题,本人菜鸟,请教各位达达

}

return OK;
}

Status Locate(Array A,va_list ap,int &off){
off=0;
int i,ind;
//va_start(ap,int);
for(i=0;i<A.dim;i++)
{

return OK;
}



int main()
{
Array A;int off;
InitArray(A,5,6,6,4,4,4);
Locate(A,4,5,2,3,1,off);
}

各位达达,我就是Status Locate(Array A,va_list ap,int &off)参数不会使用,英文学得不好也看不懂帮助,希望能给予解答,在这小弟谢谢花时间在这种白痴问题上的老鸟们了~~
