#include<stdio.h>  
int main()  
{  
    double arr[5][3]={{960.00,129500.00,1080.00},{10.30,27.57,8.20},  
    {297.47,97000.00,264.80},{62.70,1635.00,3.60},{0.0298,27.80,0.23}};  
    printf("---------------------------------------------------\n");  
    printf("COUNTRY     AREA(10K km2)  POP.(10K)  GDP(Billion$)\n");  
    printf("---------------------------------------------------\n");  
    printf("China        %12.2lf%11.2lf  %.2lf\n",arr[0][0],arr[0][1],arr[0][2]);  
    printf("Iceland      %12.2lf%11.2lf  %.2lf\n",arr[1][0],arr[1][1],arr[1][2]);  
    printf("India        %12.2lf%11.2lf  %.2lf\n",arr[2][0],arr[2][1],arr[2][2]);  
    printf("Madagascar   %12.2lf%11.2lf  %.2lf\n",arr[3][0],arr[3][1],arr[3][2]);  
    printf("Maldive      %12.4lf%11.2lf  %.2lf\n",arr[4][0],arr[4][1],arr[4][2]);  
    printf("---------------------------------------------------\n");  
    return 0;
