Thread: printing a portion of elements within an array

I have a small uni task where I have to switch lower case characters to uppercase characters from a user input within an array, up to a max of 20 characters. if the user inputs a number of characters that is less than the maximum specified, i was wondering how you would go about printing these without printing the garbage data from the array. the only way I can think of doing this is by having the user specify how many they are going to enter, and looping over that number of indexes within the array. im fairly new to c programming and would appreciate any and all help

If the former, you could split the input into tokens, separated by spaces, then loop and capitalize.

If the latter, you can loop through the input until you hit the null terminator '\0', capitalizing on the way.

This is off the top of my head. An example of expected output could narrow down a possible solution.

its the latter, would the user have to input the null terminator?

an example would be:
input = abcdef
output = ABCDEF

I figured it out, thanks for all the help

No. Users don't input the null terminator. And, apologies, when I said last night you could search for the null terminator, I meant to say they could look for '\n', which is the new line characters. That's what would appear on user input.

Cool! What was your solution?
