实验9 指针（1）答案此答案为书本上实验9 指针（1）的答案，实验x就是对应的9-x.实验一的足迹：#includevoid main()int ia23=2,4,6,8,10,12,(*pa)3,i,j;pa=ia;scanf(%d,%d,&i,&j);printf(ia%d%d=%dn,i,j,*(*(pa+i)+j);*实验9.2*实验二的足迹：#includevoid main() int ia,ib,*pa=&ia,*pb=&ib,*p; scanf(%d,%d,pa,pb); if(*pa*pb) p=pa;pa=pb;pb=p; printf(%d=%dn,*pa,*pb);*实验9.3*实验三的足迹：#includefun(int *pa,int *pb) int itemp; itemp=*pa;*pa=*pb;*pb=itemp; void main() int ia,ib; int *pa,*pb; scanf(%d,%d,&ia,&ib); pa=&ia; pb=&ib; if(iaib) fun(pa,pb); printf(%d,%dn,*pa,*pb);*实验9.4*实验四的程序：#includefun() int *pa,i,ia5; pa=ia; for(i=0;i5;i+) scanf(%d,pa+); printf(n); for(i=0;i5;i+) printf(%d,iai); printf(n); void main() fun(); *实验9.5*实验五的程序：#includevoid main() int ia, *pa=&ia; printf(请输入一个整型变量ia:n); scanf(%d,&ia); printf(%dn,*pa);*实验9.6*实验六的程序：#includefun(int a,int b) int c; c=a; a=b; b=c; printf(交换后的a,b的值为：%d,%dn,a,b);void main() int *ia,*ib; printf(请输入ia和ib两变量的值：n); scanf(%d,%d,&ia,&ib); fun(ia,ib);*实验9.7*实验七的程序：*实验9.8*实验八的程序：#includevoid main()int iA,iB,*PI;int *max(int iX,int iY);scanf(%d%d,&iA,&iB);PI=max(iA,iB);printf(max=%dn,*PI);int *max(int iX,int iY)if(iXiY)return &iY;elsereturn &iX;*实验9.9*实验九的程序：#include#includeint callfun(int (*pfun)(int iA,int iB),int iA,int iB);int fmax(int iA,int iB);void main()int iA,iB;printf(输入两个整数:);scanf(%d%d,&iA,&iB);printf(%d和%d的最大值是%dn,iA,iB,callfun(fmax,iA,iB);int callfun(int (*pfun)(int iA,int iB),int iA,int iB)int fvalue;fvalue=(*pfun)(iA,iB);return fvalue;int fmax(int iA,int iB)return(iAiB?iA:iB);#include#includeint callfun(int (*pfun)(int iA,int iB),int iA,int iB);int fmax(int iA,int iB);void main()int iA,iB;printf(输入两个整数:);scanf(%d%d,&iA,&iB);printf(%d和%d的最大值是%dn,iA,iB,callfun(fmax,iA,iB);int callfun(int (*pfun)(int iA,int iB),int iA,int iB)int fvalue;fvalue=(*pfun)(iA,iB);return fvalue;int fmax(int iA,int iB)return(iAiB?iA:iB);*实验十*实验十的程序：#define N 3#define M 3#includestdio.hselect(int iANM,int *iN)int i,j,irow=1,icolum=1;for(i=0;iN;i+)for(j=0;jiAirowicolum)irow=i;icolum=j;*iN=irow;return iAirowicolu
