在Python中,如果你有一个使用ctypes库创建的c_char_array,并且想要将其转换为Python字符串,你可以按照以下步骤进行操作:1. 明确c_char_array的来源和格式 首先,确保你已经使用ctypes库创建了一个c_char_array。例如,你可能有一个C风格的字符数组,它使用ctypes来表示: ...
string-name.c_str(); Copy At first, we use c_str() method to get all the characters of the string along with a terminating null character. Further, we declare an empty array of type char to store the result i.e. result of the conversion of string to char array. Finally, we use...
for(int i=0;i<len>>1;i++) { c=arr[i]; arr[i]=arr[len-1-i]; arr[len-1-i]=c; } string resultstr=new string(arr); 3)充分利用.NET的特性,使其效率达到较高水平。 char[] charArray = "abcde".ToCharArray(); Array.Reverse(charArray); string resultstr = new string(charArray))...
std::stringstr; chararray[]="Hello World"; for(inti=0; array[i]!=0; i++) str+=array[i]; //--- std::stringstr; chararray[]="Hello World"; str=array; Use of NULL is discouraged in C++ because it can be redefined to be anything one wants -- c++ standards do not dictate wh...

char cHomeTeamFaceOffsPercentageWon[100]; memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100); After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%". Then, I use std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon); szwPercentageWon is then...
