题目:

下列给定程序中fun()函数的功能是:将n个无序整数从小到大排序。 请改正程序中的错误,使它能得出正确的结果。 注意;不要改动main函数,不得增行或删行,也不得更改程序的结构。 试题程序: #include <conio.h> #include <stdio.h> #include <stdlib.h> fun(int n, int *a) { int i,j,p,t; for (j=0;j<n-1;j++) { P=j; /***************found*******************/ for(i=j+l;i<n-1;i++) if (a[p]>a[i]) /***************found*******************/t=i; if (p!=j) {t=a[j];a[j]=a[p];a[p]=t;} } }putarr( iht n,int *z) {int i; for (i=l;i<=n;i++,z++) { printf("%4d",*z); if (!(i%10)) printf("\n"); } printf ("\n"); } main () {int aa[20]={9,3,0,4,1,2,5,6,8,10,7},n=11; clrscr(); printf("\n\nBefore sorting %d numbers:\n",n); putarr(n,aa); fun(n,aa); printf("\nAfter sorting %d numbers:\n",n);putarr(n,aa); }

如图所示,两根相距为l的平行直导轨ab、cd、b、d间连有一固定电阻R,导轨电阻可忽略不计;MN为放在ab和cd上的一导体杆,与ab垂直,其电阻也为R;整个装置处于匀强磁场中,磁感应强度的大小为B,磁场方向垂直于导轨所在平面(指向图中纸面内);现对MN施力使它沿导轨方向以速度v(如图)做匀速运动;令U表示MN两端电压的大小,则(  )

A.U=vBl,流过固定电阻R的感应电流由b到d

B.U=vBl,流过固定电阻R的感应电流由d到b

C.U=vBl,流过固定电阻R的感应电流由b到d

D.U=vBl,流过固定电阻R的感应电流由d到b

In June 1985, two British mountaineers Joe Simpson and Simon Yates made the first-ever climb of the 21,000-foot snow-covered Siula Grande mountain in Peru.

If I died, well, that wasn’t so (37) , but I wouldn’t have (38) waited for it to happen. The (39) of dying no longer affected me as it had in the crevasse at first. I now had a chance to (40) it and struggle against it.

The survival of Yates himself was (41) . That Simpson somehow found a way of (42) out of the crevasse after 12 hours and then crawled and (43) himself six miles back to camp, (44) three days and might without food or drink, would be considered as a heroic fiction. But in fact it was so (45) .
