Thread: log and restore

I need to log what I type while the program is running.
this is saved in a text file.
Then next time I run the program I have the choice of restoring what is stored in the log file.

This a simple version of my code.

Code:

#include <stdio.h>
#include <string.h>

void Log();
void Save();
void Del();
void Dir();

typedef struct {
	char n;
	struct files *next;
}files;

struct root {
	files files[50];
	int count;
}root;

static int h;

int main() {

int choice;

root.count = 0;
h = root.count;

Log();

do {
         printf("\nPlease select an option (1-4):\n");
         printf("1) Save\n");
         printf("2) Del\n");
         printf("3) Dir\n");
         printf("4) Quit\n");
      
         scanf("%d",&choice);
      
         switch (choice) {
            case 1:
               if (h <50)
                  Save();
               else 
                  printf("Directory Full\n");
               break;
            case 2:
               Del();
               break;
            case 3:
               if (h == 0)
                  printf("No Files Found\n");
               else
                  Dir();						
               break;
            case 4:
               break;
            default:
               printf("Invalid choice\n");
               break;
         }
      } while(choice != 4);
fclose(outfile);
return 0;
}

void Log() {
	char filename[25];
	printf("Enter Log filename -> ");
	scanf("%s", filename);  
 	outfile = fopen(filename, "a");
}

void Save() {

	printf("\nEnter a char: ");
	scanf("%s",&root.files[h].n);
    
	h++;
	root.count = h;
}

void Del() {
	int i;
	char c;
	char hex = 0xE5;
	printf("\nEnter a char to del: ");
	scanf("%s",&c);
	for(i=0; i < h; i++) {
		if (root.files[i].n == c) {
			root.files[i].n = hex;
		}
	}
}

void Dir() {
	int i;
	char hex = 0xE5;
	for(i=0; i < h; i++) {
	                 if (root.files[i].n != hex){
			printf("%c\n",root.files[i].n);
		}
	}
}

Can you be more specific.

you don't have to give exact code.
