Write a program to find cube of a number

Write a program to find cube of a number.
Used Function

1. #include <stdio.h>
2. 
   
3. int cube(int num);
4. 
   
5. int main()
6. {
7.     int num;
8.     int c;
9.     
10.     printf("Please enter a number: ");
11.     scanf("%d", &num);
12.     
13.     c = cube(num);
14. 
    
15.     printf("Cube of %d is : %d", num, c); 
16.     
17.     return 0;
18. }
19. 
    
20. int cube(int num) {
21.     return (num*num*num);
22. }

Used Recursion

#include<stdio.h>

int iterator = 2;
int givenValue=0;
int cube(int num)
{
  if(!iterator)
  {
    printf("Cube of %d is : %d ", givenValue, num/givenValue);
    return;
  }
  else
  {
    iterator--;
    cube(num*num);
  }
}

int main()
{
  int n=0;
  printf("Enter the number to find the cube\n");
  scanf("%d",&givenValue);
  cube(givenValue);
}



//maybe the below program is incorrect

1. #include <stdio.h>
2. 
   
3. int cube(int);
4. 
   
5. int main()
6. {
7.     int n;
8.     int c;
9.     
10.     printf("Please enter a number: ");
11.     scanf("%d", &n);
12.     
13.     c = cube(n);
14. 
    
15.     printf("Cube of %d is : %d", n, c); 
16.     
17.     return 0;
18. }

20. int cube(int num) {
21.     return (num*num*num);
22. }
