Question

I have a small problem in c++ I need a code whose output character string is formed from the characters of the source string with even ordinal numbers. Please help me

Answer 1

char A B C D E F
index 0 1 2 3 4 5

B, D and F are all in odd indices ...
Which is it? odd or even?

Answer 2

Alright, here's one way to implement it, not in code, though I'm sure you can figure it out

Let is_odd = false
For each character in text
If is_odd
Print the character
End if
Let is_odd = NOT is_odd
End For

Here <is_odd> initialized with false cause we begin loop from 1st character (index 0 ~ even), and <is_odd> will be inverted on each iteration.

Answer 3

From index i=1 to str.length, print str[I] with i incrementing by 2=> i+=2 . simple.

Answer 4

Pls post your try ..Daniel Alexis

Answer 5

Sorry for the little inconvenience 😅😅I'm a little bad at C++ I'm pretty good at Python.Please you could make a very concrete example so that I could understand better.Please.

Answer 6

Thx

Answer 7

// I hope this link helps you

// or

for (int i=97; i<=122; i++) if (i%2==0) cout<<(char)i;

Answer 8

Thx

Answer 9

I will start very soon.Duty is for tomorrow 😭

Answer 10

Can you illustrate with example?

Answer 11

Sorry, Odd

Answer 12

Okay so from the illustration above
You can use the modulus operator to check if it odd the you just some them up

Answer 13

I will try to figure out how to implement what you are telling me...tomorrow I have several exams of programmation.si I had the code already written, it would have made it easier for me.

Answer 14

Loop through the characters of the source string. Check whether the character is even. If so, then print it.

if (source_string[i]&1==0)
cout << source_string[i];

Answer 15

Thank you very much but I don't understand, because C++ is not really my field.

Answer 16

Do you have a code already written?

Answer 17

Daniel Alexis you might want to start learning C++ from the Sololearn tutorial. There you can learn about the char type, string type, arrays, input, output, loops, and all the syntax you need for this.

I managed to display bdf but the teacher tells me that I must indicate abcdef too. Please help me.

Answer 20

Daniel Alexis copy the code and paste in SL playground and save, share link here.. That's helps find easy solution.

Do you mean, you needed output is :
abcdefg
bdf

If yes, after 1st loop : print s
Like
cout<<s<<endl;
