int main() { int n, rev = 0, remainder; printf("Enter an integer: "); scanf("%d", &n); while (n != 0) { remainder = n % 10; rev = rev * 10 + remainder; n /= 10; } printf("Reversed number = %d", rev); return 0; } Also, this program works only with positive numbers. We will take input from the user and then will print the reverse of that number. Our program will take one integer number as an input from the user, reverse it and print out the reverse number. This program will read an integer positive number and reverse that number.For Example input number is 1234 after reversing number will be 4321. The input begins with an integer indicating the number of integers that follow. In this method, we neither reverse a list in-place(modify the original list), nor we create any copy of the list. The array is a fixed size data structure. Ex: If the input is: 5 2 4 6 8 10 the output is: 10 8 6 4 2 To achieve the above, first read the integers into a vector. for coding simplicity, follow each output integer by a space, including the last one.
