I'm working on this code, and it's not finished yet. But while testing the add new contacts function and printing function, I get this strange output. Everythin looks ok as long as I'm not adding more than one contact. What am I doing wrong here?

```
//Libraries:
#include <stdio.h>
#include <stdlib.h>

//Function prototypes
int showMenu(); //Shows user options

//Main function
int main() {

    //Variable declerations
    int i = 0;
    int iOption = 0;
    int iContacts = 0;
    char *cPhoneBook_name;
    int *iPhoneBook_nr;

    cPhoneBook_name = (char *) calloc(1, 80 * sizeof(char));
    iPhoneBook_nr = (int *) calloc(1, sizeof(int));

    do {

        //Memory check
        if(cPhoneBook_name == NULL || iPhoneBook_nr == NULL){
            printf("\nOut of Memory!\n");
            return;
        }

        //Show menu
        iOption = showMenu();

        switch (iOption) {
            case 1: //Add contact
                printf("\nEnter name:\n");
                scanf("%s", &cPhoneBook_name[iContacts]);
                printf("\nEnter number:\n");
                scanf("%d", &iPhoneBook_nr[iContacts]);
                cPhoneBook_name = realloc(cPhoneBook_name, 80 * sizeof(char));
                iPhoneBook_nr = realloc(iPhoneBook_nr, sizeof(int));
                iContacts += 1;
                break;
            case 2: //Modify contact
                //Code here
                break;
            case 3: //Show contacts
                for(i = 0 ; i < iContacts ; i++) {
                    printf("\n%s %d\n", &cPhoneBook_name[i], iPhoneBook_nr[i]);
                }
                break;
            case 4: //Free memory (delete contacts)
                free(cPhoneBook_name);
                free(iPhoneBook_nr);
                break;
        }
    }while(iOption != 5);//Exit if iOption is 5;

    system("clear");
    return 0;
}

//Function definition - showMenu()
int showMenu() {

    int iOption = 0;

    //system("clear");

    printf("\n   Phone book   \n");
    printf("------------------------\n");
    printf("1. Add new contact.\n");
    printf("2. Edit existing contact\n");
    printf("3. Show contact(s)\n");
    printf("4. Clear phone book\n");
    printf("5. Exit\n");
    printf("------------------------\n");
    printf("Option --> ");
    scanf("%d", &iOption);

    return iOption;
}
//---------------------------------------------------------
