hi
#include <iostream>
using namespace std;
int main()
{
int i,count=0;
string s;
char a[100];
getline(cin,s);
int b=s.size();
for(i=0;i<b;i++)
{ if(s[i]==' ')
{
count++;
i++;
}
a[count]+=s[i];
}
for(i=0;i<=count;i++)
cout<<a[i];
return 0;
}
the program is about getting a line from user and spliiting it into word by word and displaying ..the program is not working properly anybody help me

You output a few letters depending on how many there was spaces in the input

Not exactly what the stated goal is

if i have understood correctly

thanks for all the answer

now i feel like i dont know anything😐

thanks

ill ask
Francesco
Btw i don't change very much of your code, i add only a vector instead a char array. If you want a more quick solution use strtok

Netbeans is an IDE, if what you meant ask for how to use mysql in your code, then you should look at the documentation of mysql

Ok.i will check the command.thank you

installed libdb++-dev
and compiled the program once agin.
still i have same issue.

link file means?
Compile source files, you get object files.
Link object files, you get static/dynamic libraries or executable files.
(preprocessing and assembly are ignored in this explaination.)
When you execute g++ foo.cpp, the tool chain helps you to compile and then link. However, after the success of compilling, ld, the linker, reports the symbol undefined error. This is because that in your source file, you request some functions or variables that are defined in other libraries, but you failed to link them together.
As stated by Mester, you have to get the libraries (by sudo apt-get install bar), and then explicitly link them with your object file(s) (by -lbar).
Google is your friend.

Thank you Liam ,for information.
I will try as you said.

Hi Liam,
Have a doubt.Once compiled the sourcefile we will get object file.I am not able to create the object file ,because while compiling i am getting the error.
Then how can i explicitly link the libraries with object file using -lbar?

The errors you pasted above are not compilling errors, they are linking errors. As stated above, when you are running g++ foo.cpp, the tool chain (g++) will do preprocessing, compilling, assembly and linking for you. That is, g++ is an all-in-one command.
For linking a library named bar, just give the flag -lbar to g++.
