测试用例生成|第2组(随机字符，字符串和随机字符串数组)

集合1(随机数，数组和矩阵)

• 生成随机字符

  // A C++ Program to generate test cases for
  // random characters
  #include
  using namespace std;
    
  // Define the number of runs for the test data
  // generated
  #define RUN 5
    
  // Define the range of the test data generated
  // Here it is 'a' to 'z'
  #define MAX 25
    
  int main()
  {
      // Uncomment the below line to store
      // the test data in a file
      // freopen ("Test_Cases_Random_Character.in", "w", stdout);
    
      // For random values every time
      srand(time(NULL));
    
      for (int i=1; i<=RUN; i++)
          printf("%c\n", 'a' + rand() % MAX);
    
      // Uncomment the below line to store
      // the test data in a file
      // fclose(stdout);
      return(0);
  }
  

• 生成随机字符串

  // A C++ Program to generate test cases for
  // random strings
  #include
  using namespace std;
    
  // Define the number of runs for the test data
  // generated
  #define RUN 100000
    
  // Define the range of the test data generated
  // Here it is 'a' to 'z'
  #define MAX 25
    
  // Define the maximum length of string
  #define MAXLEN 100
    
  int main()
  {
      // Uncomment the below line to store
      // the test data in a file
      // freopen ("Test_Cases_Random_String.in", "w", stdout);
    
      //For random values every time
      srand(time(NULL));
    
      int LEN;    // Length of string
    
      for (int i=1; i<=RUN; i++)
      {
          LEN = 1 + rand() % MAXLEN;
    
          // First print the length of string
          printf("%d\n", LEN);
    
          // Then print the characters of the string
          for (int j=1; j<=LEN; j++)
              printf("%c", 'a' + rand() % MAX);
    
          printf("\n");
      }
    
      // Uncomment the below line to store
      // the test data in a file
      // fclose(stdout);
      return(0);
  }
  

• 生成随机字符串数组

  // A C++ Program to generate test cases for
  // random strings
  #include
  using namespace std;
    
  // Define the number of runs for the test data
  // generated
  #define RUN 1000
    
  // Define the range of the test data generated
  // Here it is 'a' to 'z'
  #define MAX 25
    
  // Define the range of number of strings in the array
  #define MAXNUM 20
    
  // Define the maximum length of string
  #define MAXLEN 20
    
  int main()
  {
      // Uncomment the below line to store
      // the test data in a file
      // freopen ("Test_Cases_Array_of_Strings.in", "w", stdout);
    
      //For random values every time
      srand(time(NULL));
    
      int NUM; // Number of strings in array
    
      int LEN;    // Length of string
    
      for (int i=1; i<=RUN; i++)
      {
          NUM = 1 + rand() % MAXNUM;
          printf("%d\n", NUM);
    
          for (int k=1; k<=NUM; k++)
          {
              LEN = 1 + rand() % MAXLEN;
    
              // Then print the characters of the string
              for (int j=1; j<=LEN; j++)
                  printf("%c", 'a' + rand() % MAX);
    
              printf(" ");
          }
          printf("\n");
      }
      // Uncomment the below line to store
      // the test data in a file
      // fclose(stdout);
      return(0);
  }
