 Task

Complete the function void update(int *a,int *b). It receives two integer pointers, int* a and int* b. Set the value of  to their sum, and  to their absolute difference. There is no return value, and no return statement is needed.


Input Format


The input will contain two integers,  and , separated by a newline.


Output Format


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.


Sample Input


4

5

Sample Output


9

1


So I created this Program :-

Note : I import <math.h> header for use "abs " Command in Oder to get the absolute value .


 #include <stdio.h>

#include <math.h>

void update(int *a,int *b) {
    // Complete this function  
    *a=*a+*b;
    *b=abs(*a-(2**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;
}

Target : Add History Option and make more Accurate In this case I was trying to add a option which can remember past operations and return them when we want with full details ;such as our inputs, operation we done and result. first of all I recoded option called "RESET" which we can rest our calculations rest our process as we can reset our process either after we select the operation and either while we entered onr number also. i used a while loop and  add all the operators in to it as only run program while return is true, then coded for "terminate " option and "reset option" cause some times we maybe have to reset all in this stage too.   def select_op ( choice ):   if ( choice == '#' ):     return - 1   elif ( choice == '$' ):     return 0 and when return -1 for choice its terminating and exiting from program if ( select_op ( choice ) == - 1 ):     #program ends here     print ( "Done. Terminating" )     ex...

  Loops and Iterations Iteration is the repeated execution of the same block of code.  Why do we need Loops and Iterations ? Why do we repeat? Let’s say that we want to enter marks for a student and check to see if the student has passed the exam by getting more than 50 marks. We would write one line of code for one student. Now let’s say thea we have 5 students and we want to do the same. One way of doing this is to copy the code written for one student 5 times.  Is this the best way of doing this? If we had a way of writing the code once yet repeat it 5 times. it would be easier to write and if necessary, change languages allow us a way to repeatedly execute code multiple times.   We already know how to write code that goes in a sequence. We also we know how to write code to check some condition and decide which way to go usingif-else and switch- case in python. We can also repeat or iterate as shown in the diagram. Let's look at how this works. We have 5 grades in...
