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: ...
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))...
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...

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...
1st) you declared larray as const char*, and yet you assigned a value to itThat's not a problem. nevermore28 wrote: if you want to assign a c - string to std::string, use the string member function assign:No need to do that The problem is that you provide a std::string to pr...
