Exercise 1: Ask the user to enter n number and return the maximum and minimum Exercise 2: Write a C program to find the reverse of a given string using pointers. Exercise 3: Write a C program in which you define a function that exchanges the contents of two given integers if they have the same sign (both negative or both positive), otherwise, it places the sum of the two in the first integer and their product in the second integer (Use passing by reference). Call this function in main(). Exercise 4: Write a C program to check whether a given string is palindrome or not, using pointers. Every line in the code should be commented and the code should be well explained. The solution should be submitted in the platform as a PDF file Exercise 1: Ask the user to enter n number and return the maximum and minimum Exercise 1: Ask the user to enter n number and return the maximum and minimum
