please could anyone help me with this assigment!!!

which contains pointers and functions

BTW----> iam a biginner

here is the problem:

Write a complete C program to compute the least common divisor (LCD). The program should reverse and sum the digits of the given integers. Use the following functions with pointers:

Function Fun_1 to compute the least common divisor

Function Fun_2 to reverse and sum the digits of the given integer

Sample Run:

Enter Your Choice:

|1 – To Reverse and Sum the Digits

|2 - To compute LCD

|3- Exit

………………………………….

1

Input the given numbers

Num1: 123

Num2: 456

Reverse of Num1: 321

Sum of Num1 digits: 6

Reverse of Num2: 654

Sum of Num2 digits: 15

--------------------------------------------------------------------------------

i was able to find some codes, maybe it's usefull

this one for the sum

and this one for the inverseCode:#include <stdio.h> int main() { int x,y, sum = 0; printf("Enter the number \n"); scanf("%d",&x); for (x!=0;y=x%10;x/=10) sum =sum+ y; { printf("The sum is %d\n", sum); } return 0; }

thanks...Code:#include<stdio.h> main() { int num, rev=0; printf("\n Enter the number\n "); scanf("%d", &num); while(num>0) { rev = (rev * 10) + (num % 10); num = num / 10; } printf("\n Reverse of the number is %d", rev); return(0); }
