C Language

Program using File Access: Ask user to input details of book (File Write) and display records (File Read) 1. Title 2. Author 3. Genre 4. Total Pages 5. Publisher

**Please do add comments on how the program works. Thank you!!

Please strictly follow the following:

- Modular Code (Use functions)

- Records goes to info.dat and it grows size every time a record is added

- count.dat should hold the number of records

- Show number of records in view records

- Ask to user to add new record [Y/N] if no, the program closes (ignore case for the letter)

- View all records

- Edit selected record

- Add new record (Title, Author, Genre, Total Pages, Publisher)

- Delete selected record and can even delete all record

Structure of code should be like this (this is only a sample code)

**This needs improvements please do add the features above

#include #include #include

void readKB(){ FILE *fp; char name[20], gender; int age, count;

if((fp=fopen("count.dat","r+b"))==NULL){ fp = fopen("count.dat","w+b"); count = 1; fwrite(&count,sizeof(int),1,fp); fclose(fp); } else{ fread(&count,sizeof(int),1,fp); count++; rewind(fp); fwrite(&count,sizeof(int),1,fp); fclose(fp); } fp = fopen("info.dat", "a+b"); printf(" Please enter name of student: "); scanf("%s",name); getchar(); printf("Please enter gender of student (M/F): "); scanf("%c",gender); printf("Please enter age of student: "); scanf("%d",age); strcat(name," "); fputs(name,fp); fputc(gender,fp); fwrite(&age,sizeof(int),1,fp); fclose(fp); }

void output(){

FILE *fp; char name[20], gender; int n, age, count;

if((fp=fopen("count.dat","r+b"))==NULL){ printf("Number of records: 0. "); }

else{ fread(&count,sizeof(int),1,fp); fclose(fp); printf("Number of records: %d. ",count); fp=fopen("info.dat","r+b"); for(n=0; n

}

int main() { char ans='Y'; output(); do { readKB(); printf(" Want to add another record? (Y/N): "); } while(getche()=='Y'); }
