C语言实现矩阵翻转(上下翻转、左右翻转)

C语言实现矩阵翻转 上下翻转与左右翻转

实例代码：

#include  
  
void matrix (int m, int n, int t) 
{ 
  int arr[m][n]; 
  int i, j, k; 
  
  for (i = 0; i < m; i++){ 
    for (j = 0; j < n; j++){ 
      scanf("%d", &arr[i][j]); 
    } 
  } 
  if (t == 0){//左右翻转 
      for (i = 0; i < m; i++){ 
 for (j = n-1; j >= 0; j--){ 
   if ( j == 0 ) { 
     printf("%d", arr[i][j]); 
   } 
   else { 
     printf("%d ", arr[i][j]); 
   } 
 } 
 printf("n"); 
      } 
  } 
  else if (t == 1){//上下翻转 
    for (i = m-1; i >= 0; i--){ 
      for (j = 0; j < n; j++){ 
 if ( j == n - 1 ) { 
   printf("%d", arr[i][j]); 
 } 
 else { 
   printf("%d ", arr[i][j]); 
 } 
      } 
      printf("n"); 
    } 
  } 
} 
  
int main() 
{ 
  int m, n, t; 
  
  scanf("%d %d %d", &m, &n, &t); 
  matrix (m, n, t); 
  
  return 0; 
} 

 动态分配内存

void matrix (int m, int n, int t) 
{ 
  int i, j; 
  int **arr=(int**)malloc(m*sizeof(int*)); 
  for(i = 0; i < m; i++) 
  { 
    arr[i] = (int*)malloc(n * sizeof(int)); 
    for(j = 0; j < n;j++) 
    { 
      scanf("%d", &arr[i][j]); 
    } 
  } 
   
  if (t == 0){//左右翻转 
      for (i = 0; i < m; i++){ 
 for (j = n-1; j >= 0; j--){ 
   if ( j == 0 ) { 
     printf("%d", arr[i][j]); 
   } 
   else { 
     printf("%d ", arr[i][j]); 
   } 
 } 
 printf("n"); 
      } 
  } 
  else if (t == 1){//上下翻转 
    for (i = m-1; i >= 0; i--){ 
      for (j = 0; j < n; j++){ 
 if ( j == n - 1 ) { 
   printf("%d", arr[i][j]); 
 } 
 else { 
   printf("%d ", arr[i][j]); 
 } 
      } 
      printf("n"); 
    } 
  } 
}
