Question

C语言编程，求解

Answer 1

#define M 2

#define N 3

void printMatrix(int *a)

{

int i,j;

for(i=0;i<M;i++)

{

for (j=0;j<N;j++)

printf("%d ",*(a+N*i+j));

printf("\n");

}

}

int main()

{

int i,j,max,max_num;

int *a=(int*)malloc(M*N*sizeof(int));

int b[M]={0};

printf("输入%d个元素:\n",M*N);

for(i=0;i<M*N;i++)

scanf("%d",a+i);

printf("排序前数组a:\n");

printMatrix(a);

for (i=0;i<M*N-1;i++)

{

max=*(a+i);

max_num=i;

for (j=i;j<M*N-1;j++)

{

if(max<*(a+j+1))

{

max=*(a+j+1);

max_num=j+1;

}

}

if(max_num!=i)

{

*(a+max_num)=*(a+i);
*(a+i)=max;

}

}

printf("排序后数组a:\n");

printMatrix(a);

return 0;

}
