C++写csv文件

C++写csv文件

其中有一个点需要注意，csv芬里尔之间要用逗号隔开

p_str_filename ="D:\\1.csv";
int writelog(string p_str_filename, double p_double[])
{
   
	SYSTEMTIME timeCur;
	GetLocalTime(&timeCur);
	char t_logbuffer[1024] = {
    0 };
	sprintf(t_logbuffer, ("%04d%02d%02d_%02d:%02d:%02d:%03d,")
		, timeCur.wYear, timeCur.wMonth, timeCur.wDay
		, timeCur.wHour, timeCur.wMinute, timeCur.wSecond, timeCur.wMilliseconds);
	char tep[1024] = {
    0 };
	sprintf(tep, ("%02f,%02f,%02f,%02f,%02f\n"), p_double[0], p_double[1], p_double[2], p_double[3], p_double[4]);

	strcat(t_logbuffer, tep);
	t_logbuffer[1024 - 1] = '\0';
	FILE* FP = fopen(p_str_filename.c_str(), "a+");
	if (FP == NULL)
	{
   
		return -1;
	}
	fwrite(t_logbuffer, 1, strlen(t_logbuffer), FP);
	fclose(FP);
	return 0;
}
