LoadRunner中常用的字符串操作函数

LoadRunner中常用的字符串操作函数有:

               strcpy(destination_string, source_string);

              strcat(string_that_gets_appended, string_that_is_appended);51Testing软件测试网:J3~c:c[(wR%A2l

              atoi(string_to_convert_to_int); //returns the integer value

              itoa(integer_to_conver_to_string, destination_string, base); // base is 10

              strcmp(string1, string2); // returns 0 if both strings are equal51Testing软件测试网q%USEK

对各函数的定义:

            strcpy( ):拷贝一个字符串到另一个字符串中.

             strcat( ):添加一个字符串到另一个字符串的末尾。

            strcmp( ):比较两个字符串，如果相等返回0。

            atoi（）：转换一个ASCII字符串为一个整型。

            itoa（）：根据给定的进制，转换一个整型数据为ASCII字符串51Testing软件测试网D&VI2KD|

下面的例子使用了上面这些函数:     

Actions()

{

       char MyString1[20] = "";

       char MyString2[20] = "";

       char MyString3[20] = "Mercury2";

       char Cstring[10] = "12345";

       int Cint;

       // MyString1 is empty

       //

       lr_output_message(">>>>>>>>>> MyString1 = %s",MyString1);

       // copy "Mercury1" into MyString1

       //

       strcpy(MyString1,"Mercury1");

       // Now MyString1 contains "Mercury1"

       //

       lr_output_message(">>>>>>>>>> MyString1 = %s",MyString1);

       // Copy MyString3 into MyString2

       //

       lr_output_message(">>>>>>>>>> MyString2 = %s",MyString2);

       strcpy(MyString2,MyString3);

       lr_output_message(">>>>>>>>>> MyString2 = %s",MyString2);

       // Catenate MyString2 to MyString1

       //

       strcat(MyString1,MyString2);

       lr_output_message(">>>>>>>>>> MyString1 = %s",MyString1);

       // Cstring is converted to integer Cint

       //

       lr_output_message(">>>>>>>>>> Cstring = %s",Cstring);

       Cint = atoi(Cstring);

       lr_output_message(">>>>>>>>>> Cint = %d",Cint);

       // Cint is converted to string

       Cint = 100;

       itoa(Cint,Cstring,10);

       lr_output_message(">>>>>>>>>> Cstring = %s",Cstring);

       return 0;

}
