having trouble manipulating array of char

I'd like to remplace every 'c' in my char array into 'a'

did something like

Code:

---

while(*str!='\0')
{
    if(*str=='c')
      //thought i could do *str='a' but i guess i cannot
    *str++;
}

---

how can i do so? sorry for my newbieness

since you said it s an char array ....
try this

Code:

---


for(i=0; array[i]!='\0'; i++)
{
        if(array[i] == 'c')
        { 
                    array[i] = 'a';
          }
}

thanks

How could i then ... remove the 'c' in my array of char then? remove it completely
like ... aaacaaa would become aaaaaa

for removing it completely....
you will have to move all the values in the array one step ahead....
that is write the 4th element in the 3rd position .....5th in 4th n so on...there are various threads in the forum that have already discussed the same.... just do a search
check out this thread remove element from array

isn't there a simpler solution? what if i wanted to put the result into a new array then? instead of removing from the original i'll return a new array of char with the result.

Yes there is a simpler solution - use std::string - use std::remove_if algorithm. Regards.

yeah that is always possible....its just that you are using another array ... when the same job can be done with the existing one...
anyway ...

this is how probably you could go about it

Code:

---

int j=0;
for(int i=0; array[i]!='\0';i++)
{
        if(array[i] == 'c') continue;
        newArray[j++] = array[i];
}

:wave:

Thanks, i guess i'm wasting memory with that solution.

how come u use *str++, that will not work, u must use str++ if using pointers.
