function to remove newline character (fgets)

[Shinzu911]

i edited my program using the fgets function, and read about it on how to remove the new line character , but since my program deals with and array of structures i'm really confused as to how i go about making a function for this. e,g

void remove_newline(what should be my arguments)
{
     int x=0;     
     for(x=0; x<what ;x++){
           if ( str[i] == '\n' ){
              str[i] = '\0';
           }           
     }
}
what should i put to be less that x as it's an array of structures and the size of each structure member is different

here is my code:

#include <stdio.h>
#include <string.h> 


struct employee
{
       int employee_ID;
       char employee_name[50];
       int employee_age;
       char employee_DateOfBirth[10];
       char employee_address[70];
       char employee_TelNo[20];
       float emplayee_salary;
       
}employee_array[50];  // structure variable 


void print_line();     // function prototypes
void add_employee();
void edit_employee();
void delete_employee();
void search_employee();
void print_employee();
void remove_newline();


int main()
{
    int option;
   //clrscr();
   print_line();
   printf("This program provides the functionality to \n");
   printf("interface with an employee information system.");
   print_line();
   printf("Enter  [1]   -   to enter employee profile \n");
   printf("Enter  [2]   -   to edit employee \n");
   printf("Enter  [3]   -   to delete employee \n");
   printf("Enter  [4]   -   to search for employee \n");
   printf("Enter  [5]   -   to print employee information \n");
   printf("Enter  [0]   -   to exit\n\n");
   printf("Please select an option:\t");
   scanf("%d",&option);
   getchar();
   while(option != 0) 
   {
           switch(option)
                   {
                       case 1: add_employee();
                       break;
                       case 2: edit_employee();
                       break;
                       case 3: delete_employee();
                       break;
                       case 4: search_employee();
                       break;
                       case 5: print_employee();
                       break;
                       default:
                       printf("\n\nIncorrect Entry!,Please press enter and Try again!\n\n");
                       getch();
                   }
      printf("\n\n");                
      print_line();
      printf("This program provides the functionality to \n");

The parameter should be a char*. Also, I suggest using strchr to find the newline character. If it exists, you then set it to be a null character.
