一个基本算法，标准的欧几里得距离

BCB写的 首先是include


#include <math.h>
#include <vector>


using


using std::vector;


struct

struct point{
    public :
    int X;
    int Y;
};

struct p_result{
    public :
    point p1;
    point p2;
};


全局

vector<point> loli;

正题：C_point函数

p_result C_point(void){
    int i,j;
int dmin=10000;
double d;
int i1,i2;
int count;
count=XXXXXXXze();
point result;
point result2;

for (i = 0; i < count-1; i++) {
    for (j = i+1; j < count; j++) {

        int in1,in2;

        in1=pow((loli[i].X-loli[j].X),2);
        in2=pow((loli[i].Y-loli[j].Y),2);

        d = sqrt(in1+in2);

        if (d < dmin) {
            dmin = d;
            i1=i;
            i2=j;
        }
    }
}

result.X = loli[i1].X;
result.Y = loli[i1].Y;

result2.X = loli[i2].X;
result2.Y = loli[i2].Y;

p_result re;
re.p1 = result;
re.p2 = result2;

return (re);

}
