Question

1. Write a C function named find that receives a one-dimensional array of type integer named arr and its size of type integer. The function fills the array with values that are the power of four (4^n) where n is the index. After that, the function must select a random index from the array and move the array elements around the element stored in the randomly selected index Example arr = [1, 4, 16, 64, 256) if the randomly selected index was 3 then the array must be moved around 64 and the resulting array will be arr = (256, 1, 4, 16,64). Finally, the resulting array must be printed to the screen. 2. Write a main function where you define an array of type integer named myArr of size 10. Then call the function named find you defined in part 1 of this question.

Answer 1

Answer 1:

Code with explanation:

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

void find(int arr[],int size){
//i is for iteration and k stores the size of the array
int i,k=size-1;
int randNum;
  
//fills the array arr with values that are the power of 4^n(n is index)
for(i=0;i<size;i++){
arr[i]=pow(4,i);
}
  
//randNum select random index
randNum = (rand()%size);
printf("random index %d",randNum);
//move the arr elements around the elements stored in the randomly selected index
while(k!=randNum){
int temp=arr[size-1];
for(i=size-1;i>0;i--)
{
arr[i]=arr[i-1];
}
arr[0]=temp;
k--;
}
  
//print the elements of array arr
for(i=0;i<size;i++){
printf("\n%d",arr[i]);
}
}

//main function define the integer type array and call find function
int main()
{
int arr[5];
find(arr,5);
return 0;
}

Output:

random index 3
256
1
4
16
64

Answer 2:

for array of type integer named myArr of size 10. Calling the function find(arr,size)

Code with explanation:

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

void find(int arr[],int size){
//i is for iteration and k stores the size of the array
int i,k=size-1;
int randNum;
  
//fills the array arr with values that are the power of 4^n(n is index)
for(i=0;i<size;i++){
arr[i]=pow(4,i);
}
  
//randNum select random index
randNum = (rand()%size);
printf("random index %d",randNum);
//move the arr elements around the elements stored in the randomly selected index
while(k!=randNum){
int temp=arr[size-1];
for(i=size-1;i>0;i--)
{
arr[i]=arr[i-1];
}
arr[0]=temp;
k--;
}
  
//print the elements of array arr
for(i=0;i<size;i++){
printf("\n%d",arr[i]);
}
}

//main function define the integer type array and call find function
int main()
{
int myArr[10];
find(myArr,10);
return 0;
}
