二维数组中的查找问题

源代码 #ifndef SEARCHDATA_TWODIMENSION_H#define SEARCHDATA_TWODIMENSION_H#include<iostream>int searchData_TwoBinaryArray(int *arr,int lineNum,int columnNum ,int searchData){ int columnIndex=columnNum-1; int lineIndex=0; while(columnIndex>=0&&lineIndex<=lineNum-1&&arr!=NULL){ if(arr[lineIndex*lineNum+columnIndex]>searchData){ columnIndex--; }else if(arr[lineIndex*lineNum+columnIndex]<searchData){ lineIndex++; }else{ return 1; } } return 0; }#endif 测试代码 int main(){ int arr[16]={1,2,8,9,2,4,9,12,4,7,10,13,6,8,11,15}; std::cout<<searchData_TwoBinaryArray(arr,4,4,7)<<std::endl; } 来自为知笔记(Wiz)
