I need your help. We are ask to make a telephone directory program that asks your name, address, and telephone number. If the name you entered already exists, it will display that it already exists. This is what i have so far...
#include<stdio.h>
#include<conio.h>
struct file {
char name[25],address[25];
double telno;
};
char tempname[25],tempadd[25];
double tempnum;
int x;
int choice;
FILE *fp;
main()
{
struct file rec;
clrscr();
fp=fopen("TelDir.txt","a+");
while(!feof(fp))
{
fscanf(fp,"%s %s %.0lf,&tempname,&tempadd,&tempnum);
printf("\n%s\t\t%s\t\t\t%.0lf",tempname,tempadd,tempnum);
printf("\nEnter Name: ");
gets(rec.name);
if(strcmp(rec.name,tempname)==1)
{
printf("\n\nALREADY EXIST!");
printf("\n%s\t\t%s\t\t\t%.0lf",tempname,tempadd,tempnum);
getch();
}
else
{
printf("Enter Address: ");
scanf("%s",&rec.address);
printf("Enter your Telephone No.: ");
scanf("%lf",&rec.telno);
printf("%s\t\t%s\t\t%\t\t0lf",rec.name,rec.address,rec.telno);
fprintf(fp,"%s %s %.0lf\n",rec.name,rec.address,rec.telno);
}
}
fclose(fp);
getch();
}
But this thing doesn't work. I don't know where the error is. Can someone help me on this? I would really appreciate if you could help me somehow.
