and then print their average. Write a C program that accepts a string of text from the user and prints back the string without any of the vowels. For example, if the user entered "Hello, world", the program should print "Hll, wrld" Write a C program that accepts an integer in decimal from the user and prints the number of 1' bits in the integers binary representation. For example, if the user entered 14, the program should print 3 because 14 is 1110 in binary Write a C program that reads two decimal numbers x and n from the user, and prints "true" if the nth bit of x is a '1' and "false" otherwise. For example, if the user enters 17 and O, the program should print "true" because 17 is 10001 in binary and bit 0 is a'1. 4. 5. 6
