Creates an eight-element array of ints and sets the elements to the first eight powers of 2 and then prints the values. - C Array

Introduction

Use a for loop to set the values, and, for variety, use a do while loop to display the values.

Demo Code

#include <stdio.h>

int main(void)
{
  int powers_of_2[8];
  int power = 1;/* w  w w  .ja  va2 s  . c o m*/
  int i;

  for (int i = 0; i < 8; i++)
  {
    power *= 2;
    powers_of_2[i] = power;
  }
  printf("Powers of 2:\n");
  i = 0;
  do {
    printf("%d ", powers_of_2[i]);
    i++;
  } while (i < 8);
  printf("\n");

  return 0;
}
