Solution
Sure, here is the solution for your problem.
a) The C program to store the Item number, quantity sold, and Price of one item in toi.remctf file by reading values from the keyboard.
#include<stdio.h>
struct Item {
int itemNumber;
int quantitySold;
float price;
};
int main() {
FILE *fp;
struct Item item;
fp = fopen("toi.remctf", "w");
if(fp == NULL) {
printf("File cannot be opened");
return 1;
}
printf("Enter item number, quantity sold and price: ");
scanf("%d %d %f", &item.itemNumber, &item.quantitySold, &item.price);
fprintf(fp, "%d %d %.2f\n", item.itemNumber, item.quantitySold, item.price);
fclose(fp);
return 0;
}
b) The C program to read the details from toi.remctf file and calculate the total amount paid for each item.
#include<stdio.h>
struct Item {
int itemNumber;
int quantitySold;
float price;
};
int main() {
FILE *fp;
struct Item item;
float totalAmount;
fp = fopen("toi.remctf", "r");
if(fp == NULL) {
printf("File cannot be opened");
return 1;
}
while(fscanf(fp, "%d %d %f", &item.itemNumber, &item.quantitySold, &item.price) != EOF) {
totalAmount = item.quantitySold * item.price;
if(item.quantitySold > 3) {
totalAmount *= 0.95; // 5% discount
}
printf("Item No. %d Total Amount %.2f\n", item.itemNumber, totalAmount);
}
fclose(fp);
return 0;
}
Please replace "toi.remctf" with your actual file path.
