Question

PLEASE HELP!!! C PROGRAMMING CODE!!!

Please solve these functions using the prototypes provided. At the end please include a main function that tests the functions that will go into a separate driver file.

Prototypes int R_get_int (void); int R_pow void R Jarvis int start); void R_fill_array(int arrayll, int len); void R_prt_array (int arrayl, int len) void R-copy-back (int from[], int to [], int len); int R_count_num (int num, int arrayll, int len) (int base, int ex)

CODE:

#include<stdio.h>
#include <stdlib.h>

int R_get_int(){
   int n;
   printf("Enter a positive number: ");
   //taking user input number
   scanf("%d",&n);
   //checking given number is positive or not
   if(n>0){
       //if it positive return that to main
       printf("Thank you!!\n");
       return n;
   }
   else{
       //if negative warn user and again call this function
       printf("Please enter positive number.\n");
       R_get_int();
   }
      
}

int R_pow(int base, int ex){
   //if exponentia is 0 then value is 1
   if(ex==0)
       return 1;
   else
       return base*R_pow(base,ex-1);
       //multiply result with base for each time
}

void R_Jarvis(int start){
   printf("%d ",start);
   //if sequence reaches 1 then stop process
   if(start==1)
       printf("\n");
   //if it is even call it with its half
   else if(start%2==0)
       R_Jarvis(start/2);
   //if it is odd multiply with 3 and add 1
   else
       R_Jarvis(start*3+1);
}

void R_fill_array(int array[],int len){
   //for pointing index use static variable
   static index=0;
   //if index reaches ens stop calling function
   if(index==len)
       return;
   else{
       //genaraing random numners
       int rnd = (rand() % (320 + 1 - 7)) + 7;
       //store the random numbers to the array
       array[index++]=rnd;
       printf("%d ",rnd);
       R_fill_array(array,len);
   }
}

void R_prt_array(int array[],int len){
   //for pointing index use static variable
   static index=0;
   //if index reaches ens stop calling function and print last value
   if(index==len-1)
       printf("%d",array[index]);
   else{
       //print each element
       printf("%d , ",array[index++]);
       R_prt_array(array,len);
   }
}

void R_copy_back(int from[],int to[],int len){
   //for pointing index use static variable
   static index=0;
   if(index==len)
       return;
   //coping the elements
   to[index]=from[len-index-1];
   printf("%d ",to[index++]);
   R_copy_back(from,to,len);
}

int R_count_num(int num,int array[],int len){
   static index=0,count=0;
   //if index reaches ens stop calling and return count
   if(index==len)
       return count;
   //for occurence increases the count
   if(array[index++]==num)
       count++;
   R_count_num(num,array,len);
}
int main(){
   int array[5],to[5];
   printf("Function1:\n");
   printf("Function1 returns %d\n",R_get_int());
   printf("\nFunction2:\n");
   printf("5 power 3 is %d\n",R_pow(5,3));
   printf("\nFunction3:\n");
   printf("Jarvis sequence for 15 is: ");
   R_Jarvis(15);
   printf("\nFunction4:\nArray elements are: ");
   R_fill_array(array,5);
   printf("\n\nFunction5:\nArray elements are: ");
   R_prt_array(array,5);
   printf("\n\nFunction6:\ncopied Array elements are: ");
   R_copy_back(array,to,5);
   printf("\n\nFunction7:\n22 occurs %d times in the array.",R_count_num(22,array,5));
}
