Demonstrate how strcat() and strcmp() function work in C? [Marks-5] [CO-4, Level-1] 4. a) Write a c program to implement and call a user-defined function that will take one number as input and check whether the given number is divisible by 5 or not. If divisible by 5, print "Penta" otherwise print "Regret". (hints: function with arguments but no return). [Marks-5] [CO-4, Level-3] 4. b) What is the difference between user-defined function and library function? What is the need for a user-defined function. [Marks-5] [CO-4, Level-2]
