Thread: Why does program jump over first data input line?

Code:

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

void menu (void);
void locate(short x, short y);
//void removeScrollbars(void);
void enterBill(void);

struct A
    {
        char bill[6];
        char date[10];
        char descr[36];
        char euros[9];
        char code[6];
    };

int main(void)
{
    //removeScrollbars();
    menu();

}

void menu(void)
{
    system("@cls||clear");
    char s;
    locate(5,5); printf("1 = Enter a bill");
    locate(5,6); printf("2 = Retrieve a bill");
    locate(5,7); printf("3 = Correct a bill");
    locate(5,8); printf("4 = Enter a description");
    locate(5,9); printf("5 = Change a description");
    locate(5,11); printf("Make a selection: ");
    s = getchar();
    if (s == '1') enterBill(); else exit(0);
}

void enterBill(void)
{
    system("@cls||clear");
    struct A B;

    strcpy(B.bill,"");
    strcpy(B.date,"");
    strcpy(B.descr,"");
    strcpy(B.euros,"");
    strcpy(B.code,"");

    // This entry line is being passed over

    char *p;
    locate(5,5);printf("Bill numer");locate(30,5);printf(": ");
    fgets(B.bill, sizeof(B.bill),stdin);    
    if( (p = strchr(B.bill,'\n')) != NULL ) *p = '\0';
        
    locate(5,6);printf("Enter date");locate(30,6); printf(": ");
    fgets(B.date, sizeof(B.date),stdin);                         
    if( (p = strchr(B.date,'\n')) != NULL ) *p = '\0';

    locate(5,7);printf("Amount");locate(30,7);printf(": ");
    fgets(B.euros, sizeof(B.euros),stdin);                
    if ( (p = strchr(B.euros,'\n')) != NULL ) *p = '\0';

    locate(5,8);printf("Code");locate(30,8);printf(": ");
    fgets(B.code, sizeof(B.code),stdin);
    if ( (p = strchr(B.code,'\n')) != NULL ) *p = '\0';


    FILE *C;
    C = fopen("data2","ab");
    fwrite(&B,sizeof(struct A),1,C);
    fclose(C);            

}

void locate(short x, short y) 
{
    COORD pos = {x, y};
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

Above is a test program to find out why the program jumps over the first entry line when you select 1 in the menu. I am showing a lot of code hoping my question will be clear. Please help. Many thanks, Zach.
