I mean after exiting the program interred data will be saved and when the user will re run the program they will got those data. As I am a beginner of C programming so I am little confuse that how can I do this ? will I need to use any special memory function or can I do this with malloc() function ?? If you know what will work for this then please share your experience with me. It will help me a lot for my simple mini project.
