My Brother In Christ!
We Christians believe the scriptures only and obey.
In the beginning, he made them one man, one wife.
Now you are born again, your first wife is your wife if you have performed her marital rites, if not the whole context changes.
The second wife is adultery, if she has children for you, you must take responsibility for all children, for this is the Will of God! You dont just send her out, get her accommodation, speak to her and her family.
If you are sincere with God, he will direct your paths!

Stop quoting the bible out of context bro...
.
.
will this your advice still stand if the second wive was to be your sister.
.
moreover the Bible never said a man cannot marry more than one wife.
.
.
.
.
.
God knows if I have enough money, i will marry more than two ooo... I go be father of many nation bro.

I am also from enugu.

That is harsh and uncalled for, you know!!!

What an irresponsible comment I have come across on sport section, since I joined Nairaland.

Bros I beg grow up. I don't even think you know more about football than her.
In as much as you feel you are a man.







**Am Waiting for you to call me woman wrapper!!!





Even if you do, that wouldn't take away the facts I have stated.

See person dey talk dey judge himself

WhiZTiM:
I glanced over your code and can see a bug with the second switch statement.

You are testing for roman.at(i + 1) under the premise that i < roman.size().... That's wrong cause when you reach the last element, i will go overboard. If you are ever testing i + x, then your condition should be i - x....
What i am saying is...

Your while loop should be

.....
while (i < roman.length() - 1){
.....

Thanks.... I also found few bugs out on my own too. the program now runs smoothly

codemarshal08:
hmm........your program structure is making it hard for me to scan through. Anyways, i tried to reproduce the error but your code kept giving me multiple errors different from the one you posted here

Please are you sure you were able to pass the COMPILE stage to the RUN stage ?

.yes it compiled successfully

I can't seem to find the bug in this my program

this is the error i get whenever i try to run the program


termincate called after throwing an instance of 'std::out_of_range'
what(): basic_string::at _n (which is 1) >= this->size() (which is 1)

this application has requested the Runtime to terminate it in an unusual way.
Please contact he application's support team for more information.

.

I am learning c++ as a first language and it's frustrating as hell... Please recommend any study materials most especially videos



Thanks in advance

Please I have three questions

Is there any website aside the random google search for downloading stock roms and firmwares for android phones ??

And secondly,
Aside SP flash tool, is there any other tools for flashing a rom to an android phone?

One more
Please
How can one flash china phones like none android techno, itel etcetera


Please can anyone invite me into that android forum whatsapp group?

Is it the swearing in that happened decades ago or is there another one upcoming??


Why didn't the family members go to the police earlier.


Anyways,
I pray he is found in perfect health condition and all his body parts intact.
