با سلام
یه تابع با زبان c++ نوشتم که string رو توش includ کردم میخوام با ترمینال ران کنم این دستو رو میزنم
: gcc -o a $(mysql_config --cflags) a.cpp $(mysql_config --libs)
ولی توابعش رو نمیشناسه !!!این خطا رو میده
string’ was not declared in this scope
error: request for member ‘resize’ in ‘s’, which is of non-class type ‘char*’
چطور باید ران کنم؟؟
ممنون میشم اگه حل بشه
این هم کد برنامه اس:
