Pointers In C HackerRank Problem

The program takes two integers as input. It then performs two operations on these integers: it adds the two numbers together and replaces the first number with the result, and it calculates the absolute difference between the two numbers and replaces the second number with the result.

Here is the Pointers In C HackerRank Problem HackerRank solution using CodeRankGPT:

The solution uses pointers to directly modify the values of the input integers. A temporary variable is used to store the initial value of the first integer to calculate the absolute difference after the first integer is updated. The 'abs' function is used to ensure the difference is always positive.


#include 

void update(int* a, int* b) {
    // Store the value of a in a temporary variable
    int temp = *a;
    // Add the value of b to a
    *a += *b;
    // Store the absolute difference between a and b, into b
    *b = abs(temp - *b);
}

int main() {
    int a, b;
    int* pa = &a, * pb = &b;

    scanf("%d %d", &a, &b);
    update(pa, pb);
    printf("%d\n%d", a, b);

    return 0;
}
