2、;}//综合练习2#include#includevoidmain(){FILEp;inti;floatsum=0;for(i=2;i<=10;i++)sum=sum+sqrt(i);p=fopen("design.dat","w");fprintf(p,"%13.10f",sum);fclose(p);printf("%13.10f",sum);}//综合练习3#include#include#definelen(x1,y1,x

3、2,y2)sqrt((x1-x2)(x1-x2)+(y1-y2)(y1-y2))voidmain(){FILEp;inti,j;floatc,minc;floatx[]={1.1,3.2,-2.5,5.67,3.42,-4.5,2.54,5.6,0.97,4.65};floaty[]={-6.4,4.3,4.5,3.67,2.42,2.54,5.6,-0.97,4.65,-3.33};minc=len(x[0],y[0],x[1],y[1]);for(i=1;i<=9;i++)for(j=i+1;j<
