Answer Happy

Hi all,
My assignment is to "Define a structure type struct personal
that would contain person name, date of joining and salary using
this structure to read this information of 5 people and print the
same on-screen." I have most of the code done and I understand I
can simply declare 5 variables in my structure and have the user
enter all 5 users in 1 go, however, I am trying to program the code
in a way that you can add an unlimited number of employees.
My program runs fine until I display the employee information
after running the "newPersonel" function more than once. My
previous entries get overwritten by the new entries and garbage
values are printed at times. I'm not sure how to fix this bug, any
help is appreciated.
Please comment any changes/additions/modifications
done to the code please, thank you!
Below is my code in C .
/* Define a structure type struct personal that would contain
person name, date of joining
and salary using this structure to read this information of 5
people and print the same on screen.*/
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
//Defining structure for personel
struct personel
{
char name[50];
char date[10];
float salary;
};
//Declaring and initializing global variables used throughout
the code
int count=0;
char menuInput=0;
int employeLoopCount = 0;
//Declaring new pointer variable for personel in order to store
values without declaring number of struct personel variables
struct personel *p;
/*newPersonel function is used to add new personel to the
'database'. The function will scan for number of personal to be
added stores it tempCount.
Next, the function will initialize pointer variable 'p' and
allocate the address for the values to be stored in. The loop will
begin and it will run
tempCount number of times, scanning all employee information and
storing the data in the program. The data is stored in the
corresponding variable
and variable address. The 'employeLoopCount' variable is
supposed to work as an index incrementer/counter for the number of
employes that have been added to the database
and is used to avoid any overwritting of the same data over
previous entries in case the function is called multiple times
during the same session.*/
void newPersonel()
{
int tempCount=0;
printf("How many personel will you be
adding?:\n");
scanf("%d", &tempCount);
p = (struct personel*)malloc(tempCount *
sizeof(struct personel));
for(int i = 0; i < tempCount; i++)
{
printf("\n\n------------EMPLOYEE

printf("Please enter the full
name:\n\n\n");
scanf(" %[^\n]s",
&(p+employeLoopCount)->name);
printf("\n\nPlease enter the date
joined (DD-MM-YYYY):\n\n\n\n");
scanf(" %[^\n]s",
&(p+employeLoopCount)->date);
printf("\n\nPlease enter the
salary:\n\n\n\n");
scanf("%lf",
&(p+employeLoopCount)->salary);
employeLoopCount =
employeLoopCount+1;
}
count = tempCount+count;
}
/*The viewPersoel function is a simple print function that will
print all the stored personel information to the console.

void viewPersonel()

printf("%s\t\t", p.date);
printf("$%.2lf\n", p.salary);
}
printf("\n\n");
Sleep(5000);
}
/*mainMenu function is used to have the user select what he

printf("Greetings! Would you like to view personel
records or add new personel?:\n");
printf("1 - View Personel Records\n");
printf("2 - Add New Personel\n");
printf("3 - Exit\n");
scanf(" %c", &menuInput);
}
/*The main function is composed of switch case statements that
