C Exercises: Replace every negative or null element of an array by 1 and print the array elements

C Basic Declarations and Expressions: Exercise-124 with Solution

Write a C program that reads an array of integers (length 7), replace every negative or null element by 1 and print the array elements.

Sample Solution:

C Code:

#include <stdio.h>
int main ()
{

  int array_nums[7], i, n;

  printf("Input 7 array elements:\n");
  for (i = 0; i < 7; i++)
  {

    scanf("%d", &n);
    array_nums[i] = n;

  }
  printf("\nArray elements:\n");
  for (i = 0; i < 7; i++)
  {

    if (array_nums[i] <= 0)
    {

      array_nums[i] = 1;

    }    
    printf("array_nums[%d] = %d\n", i, array_nums[i]);

  }
}

Sample Output:

Input 7 array elements:
15
12
-7
25
0
27
53

Array elements:
array_nums[0] = 15
array_nums[1] = 12
array_nums[2] = 1
array_nums[3] = 25
array_nums[4] = 1
array_nums[5] = 27
array_nums[6] = 53
