Question

I want to know why the telephone number saved as other thing.

The C++ Code will be post in the comment.

Answer 1

#include <stdio.h>
#include <stdlib.h>
void authenticity (int age);
void main ()
{ system ("title Assignment A5");
system ("color 1F");
int counter;
int g=0,f=0;
struct callersinfo
{ char callername[20];
char telno[11];
int age;
};
typedef callersinfo callperson;
callperson caller[10];
FILE *input;
input=fopen("callersinfo.dat", "w");
if (input ==NULL)
{ printf("\nThe file failed to create\n");
exit(-1);
}
printf("Fire Brigade Department\n\n");
for (counter = 0;counter <= 9; ++ counter)
{ printf("Caller number %d\n",counter+1);
printf("Enter Caller's Name: ");
scanf("%s",&caller[counter].callername);
printf("Enter Caller's phone numbers: ");
scanf("%d",&caller[counter].telno);
printf("Enter caller's age: ");
scanf("%d",&caller[counter].age);
fprintf(input,"Name: %s\n",caller[counter].callername);
fprintf(input,"Tel. No.: %d\n",caller[counter].telno);
fprintf(input,"Age: %d\n",caller[counter].age);
authenticity (caller[counter].age);
if (caller[counter].age >=10)
{ g++;
}
else
{ f++;
}
}
fclose(input);
printf("Summary:\nTotal number of callers: %d\nNumber of genuine emergency calls: %d\nNumber of fake calls: %d\n",counter,g,f);
return;
};
void authenticity (int age)
{
int type;
if (age>=10)
{ type=1;
printf("Type of call: %d\n",type);
printf("THE CALL IS A GENUINE EMERGENCY CALL.\n\n");
}
else
{ type=2;
printf("Type of call: %d\n",type);
printf("THE CALL MAY BE FAKE! BE CAUTIOUS!\n\n");

}
}

Answer 2

you mean why the telephone number is saved as a char pointer but not as an int ?

Answer 3

when i type the tel no
For example:012345678
it save as a number around 1244XXX
it should save 012345678 but not the number above....
Anything wrong with my code?
