void update(int *a,int *b) { int x = *a + *b; //initializing pointers addition inside variable. int diff = *a - *b; //initializing pointers difference inside variable.

if(diff < 0){
    diff = -diff;        //or you can use the abs( ) function for mod.
}

*a = x;
*b = diff;

}

void update(int *a,int *b) { int num1 = (*a); int num2 = (*b); num1 = (*a) + (*b); num2 = (*a) - (*b); if (num2 < 0) { num2 = -num2; } *a = num1; *b = num2;

}

void update(int *a,int *b) { int sum= (*a)+(*b); int diff= abs((*a)-(*b));
(*a)=sum; (*b)=diff; } this may help :)

Hey, this is my code. Insights would be appreciated. Happy learning!

#include <stdio.h>
#include <math.h>

void update(int *a,int *b) {
    // Complete this function 
    int temp;``
    temp = *a;  
    (*a) = (*a) + (*b);
    (*b) = abs((temp)-(*b));
}

Using Ternary Operator

void update(int *a,int *b) {
    int x=*a + *b;
    int diff=*a-*b;
    int y=(diff<0 ? -diff : diff;
    *a=x;
    *b=y;
}
