Program that will output correct sentence stucture

closed account (9L8T0pDG)
Hello,

I need this code to correctly out put a malformed sentence removing spaces and is terminated by a period.

Example: this is a TEST .

Should be : This is a test.

This code does not work right, what have I done? What needs to be done for me to fix it im stumped.

why would you name your function getline when that's already a function in the cin class ?

void takeLine(char sentence[]);

int main()

  char sentence[100];

  cout << "Enter a sentence. ";

ill try to figure out how to fix the space after the period problem and let you know if i figure it out, im still a noob q:

hmmmm interesting way there kapo.

Although that does not delete spaces, at least not for me.

And I am a noob also.

How did you do that so fast?
kapo (73)
trial and error i guess
does it do what you want ?
closed account (9L8T0pDG)
Yeah it does thank you. I guess scrap mine.

Dont you have to:

delete p;
p = NULL;
kapo (73)
i dont think so, we didnt put *p on the heap so it should delete itself after the takeLine function returns back to main.
