a Quick Question

im trying to understand why im forced to use 'cin.ignore();' in my example code
and why when i run it without 'cin.ignore();' it jumps a bit to far in my code .
its kinda anoying to not know. , pls explain to me

Code:

#include <iostream>
#include <cstring>

using namespace std;

struct database
{
    char name[256];
    char lastnume[256];
    char cellnr[256];
    char adress[256];
};

int main()
{
    struct database data;

    cout<<" Please enter your data about you !\n";
    cout<<" Please enter your name:";
    cin>> data.name;
    cin.ignore();
    cout<<" Please enter your lastname:";
    cin.getline ( data.lastnume, 256, '\n');
    cout<<" Please enter your Cell nr.:";
    cin.getline ( data.cellnr, 256, '\n');
    cout<<" Please enter your adress:";
    cin.getline ( data.adress, 256, '\n');

    cout<<"\n Name:    \t"<< data.name;
    cout<<"\n Lastname: \t"<< data.lastnume;
    cout<<"\n Cell nr.:  \t"<< data.cellnr;
    cout<<"\n Adress:   \t"<< data.adress;

    cin.get();
}

sorry for my bad english

Say you type in "Fred" and a newline
Then "Flintstone" and a newline

cin>> data.name;
// This takes "Fred"

cin.ignore();
// This takes the newline

cin.getline ( data.lastnume, 256, '\n');
// This reads "Flintstone" and a newline


Without the ignore(), the first getline call would immediately finish by reading the solitary newline left behind from your previous input.

Ideally, you should pick just ONE input style (pick getline), and then you don't get into a mixup over who is responsible for processing which character(s).



You have the same problem in C, if you mix scanf() with fgets()

got it !

You should also use std::string instead of chars.
You can also drop the "struct" keyword when declaring a variable of the struct type, ie database data instead of struct database data.

"struct" keyword i know, but its not wrong to let it there .. im new to coding so i let it be there to know what,were i done . coz that was an exercise to learn how to use structs.

It's only going to be confusing. The struct keyword is used to declare a structure. Now your structure is a type and all variables are created by typing its type first, then the name.
Not sure if you can do "class myclass myvar;".

well i used "struct" keyword coz i get color blue on it and its easy to spot in code , so in small code were i mostly know what ive done that was a good ideea to spot but for long term that could do more harm then good ... geting bad habits is bad i know ty for pointing it for me
