What two things does fopen need?
Short answer. A file name and a mode.
What must you always call at the end?
fclose.
Three file steps
| FILE *fp; |
| fp = fopen("m.txt", "w"); |
| fclose(fp); |
Remember
| fopen needs name and mode |
| Always fclose the file |
You close the program, and all your data is gone. Why? Variables vanish, so save to a file. Declare a FILE pointer. Open with fopen, a name and a mode. Close with fclose. Remember this. Fopen needs a name and mode. Always use fclose.
