Question

Problem5: (5 pts)

using c programming

Given an array of integers named “simple” of length 8 and filled as follows:

5

20

13

8

0

16

55

2

int x = 5;

int *p = &simple[3] ;

Write the values of x after each of the following executes (write unknown if cannot be determined): (hint: pointer moves to new location after each line)

x = *(p++);                                                   x = ___8_______________ p->simple[4]           

x = *( p + 1) ;                                               x = _____16______________ p- simple[4]   

x = simple[5] - *(p--);                                   x = ____16___________    p->simple[3]

x = *(--p);                                                    x = _____13__________ p->simple[2]      

x = simple[0] / simple[7];                            x = ____2________

I am not understanding how he is coming up with these answers all the way. I think the *(p++) throws me off. just looking for explanations thank you

Answer 1

code:

#include<stdio.h>
int main(){
   int simple[]={5,20,13,8,0,16,55,2}; //array initialization
   int x=5;           //initializing x
   int *p=&simple[3];       //assigning address
   x=*(p++);
   printf("%d\n",x);
   x=*(p+1);
   printf("%d\n",x);
   x=simple[5]-*(p--);
   printf("%d\n",x);
   x=*(--p);
   printf("%d\n",x);
   x=simple[0]/simple[7];
   printf("%d\n",x);
  
  
}
