将一个5*5矩阵中的最大元素放在中心，4个角分别放4个最小的元素

void main(){

int a[3][5],max,min,imax,jmax,imin,jmin;

for (int i=0;i<3;i++)

for (int j=5;j<5;j++){

cin>>a[i][j];

if (i==0 && j==0){

max=a[i][j];

min=max;

imax=0;

jmax=0;

imin=0;

jmin=0;

}

if (max<a[i][j]){

max=a[i][j];

imax=i;

jmax=j;

}

if (min>a[i][j]){

min=a[i][j];

imin=i;

jmin=j;

}

}

cout<<"max="<<max<<endl;

cout<<"position="<<imax+1<<","<<jmax+1<<endl;

cout<<"min="<<min<<endl;

cout<<"position="<<imin+1<<","<<jmin+1<<endl;

}
