String character removal

Hi,

I know how to remove certain characters from a string by using something like this:

Code:

---

string str ("Hello world!");
erase (0, 6);

---

That's great if I want to do that manually, but say if someone entered a string, how would I automatically remove every other character they entered? Sorry if this is a poor explanation, but I hope someone can help me.

Going to guess this is for an assignment. I am also going to guess that your class just taught you about loops. So... think of an implementation with loops that will remove every other character.

Unfortunately my school doesn't teach programming, stuck doing it alone. But thanks for the advice

Ah, well then here is some reading for you sir to help you in your learning :)

For loops:
for loop - cppreference.com

While loops:
while loop - cppreference.com

do-while loops:
do-while loop - cppreference.com

You can use any of these 3 to easily accomplish your goal here. I am not trying to be rude, I'm trying to help you without flat out giving you the answer.

Also for general reference:
C++ reference - cppreference.com

For a quick and easy strategy, use the STL to your advantage. The <algorithm> header is one of my favorites: remove_if - C++ Reference
