In this challenge, you will learn to implement the basic functionalities of pointers in C. A pointer in C is a way to share a memory address among different contexts (primarily functions). They are primarily used whenever a function needs to modify the content of a variable that it does not own. In order to access the memory address of a variable, ...
Complete the function void update(int *a,int *b). It receives two integer pointers, int* a and int* b. Set the value of a to their sum, b and to their absolute difference. There is no return value, and no return statement is needed. 1. a’ = a+b 2. b’ = |a-b|
Modify the two values in place and the code stub main() will print their values. Note: Input/ouput will be automatically handled. You only have to complete the function described in the 'task' section.
First, we included the required header file.Then, we defined a function that takes two integer pointers, a and b,as arguments. We also declared two integer variables, ‘sum’ and 'diff'. sum will store the sum of two integers, and diff will st...Then we declared the main function. Inside our function, we declared two integer variables, a and b, and two integer pointers, pa and pb, that point to a and b.We used the scanf function to read the inputs and called the update function to update the values of a and b.Learn how to use pointers in C to modify the content of variables in different functions.
