Write code to "de-vowel" an input string. Assume that the user provides input containing only the characters a through z (and all lowercase). Your code should create an output string that deletes all vowels from the input string, pushing the letters together to fill any gaps. For example, given the input "theturtheandthehare" your code should print out "thtrtlndthhr". Your program should create an output string from the input string, before presetning its output , and should include the following lines: char input[80],output[80]; printf("Enter a string :"); scanf("%s", input).
