I have a string manipulation questions in C, and for the question assume I have the same input which is at least ten characters in length (maybe even more). How do I 'trim' an array of characters, for example if i had a char array = "0123-45 67-89" to become "0123456789" (replacing all the dash and spaces with ''). Is there a built in function which does this other than a tokenizer? Also is there a replace a character in a string function in C?( for example in the string A234 search for all the A/a's and replace it with 1)
Another side note is how do i turn characters into integers?
