Front

The following code is intended to print each character of a phrase on its own line of code. Which answer best describes how the code will execute? Options: The code will miss the last letter. counter < phrase.length() should be replaced by counter <= phrase.length(), The loop will run infinitely. counter++ needs to be replaced with counter = counter + 1, A for loop is needed for this code to work, not a while loop., The counter increments too early and causes an out of bounds error. The counter increment should be placed after the print statement., The code will execute as intended.
