c program in computer program




C Program to reverse a number :- This program reverse the number entered by the user and then prints the reversed number on the screen. For example if user enter 123 as input then 321 is printed as output. In our program we have used modulus(%) operator to obtain the digits of a number, we store the digits in an array, pow functions of math.h is used to obtain the reverse of the given number.
