C Program to Print Negative Numbers in an Array

Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:

Operators in C Programming.
Basic Input and Output function in C Programming.
Basic C programming.

For loop in C programming.
Arithmetic operations in C Programming.

What is a negative number?

A number is said to be a negative number when that number is having a value less than “0”. It means -1,-2,-3,-4.

What is An array?

The array is a collection of similar data types. An array can store multiple values with different indexes in memory by using a single variable. The array can be both single and multidimensional.

Program to Print Negative Numbers in an Array.

In this program, we will first take the input array size and the elements from the user. Then we will separate the negative numbers from that array. After that, we will Put negative Numbers in a Separate Array. At last, we will print the separated array containing negative values.

With the help of this program, we can Print Negative Numbers in an Array.

Program Code:-

/* C Program to Print Negative Numbers in an Array */
#include <stdio.h>

#define MAX_SIZE 100 // Maximum array size

int main()
{
    //declaring the required variable for the program.
    int arr[MAX_SIZE]; // Declare array of MAX_SIZE
    int i, N;
    //i = it will hold the integer value for the loop.
    //N = it will hold the integer value for the program.
    /* Taking the Input size of the array */
    printf("Enter size of the array : ");
    scanf("%d", &N);

    /* Taking the Input elements in the array */
    printf("Enter elements in array : ");
    for(i=0; i<N; i++)
    {
        scanf("%d", &arr[i]);
    }
    //Printing the negative elements of the array.
    printf("\nAll negative elements in array are : ");
    for(i=0; i<N; i++)
    {
        /* If current array element is negative */
        if(arr[i] < 0)
        {
            //Printing the elementa
            printf("%d\t", arr[i]);
        }
    }

    return 0;
}

/* C Program to Print Negative Numbers in an Array */

#include <stdio.h>

#define MAX_SIZE 100 // Maximum array size

int main()

{

//declaring the required variable for the program.

int arr[MAX_SIZE]; // Declare array of MAX_SIZE

int i, N;

//i = it will hold the integer value for the loop.

//N = it will hold the integer value for the program.

/* Taking the Input size of the array */

printf("Enter size of the array : ");

scanf("%d", &N);

/* Taking the Input elements in the array */

printf("Enter elements in array : ");

for(i=0; i<N; i++)

{

scanf("%d", &arr[i]);

}

//Printing the negative elements of the array.

printf("\nAll negative elements in array are : ");

for(i=0; i<N; i++)

{

/* If current array element is negative */

if(arr[i] < 0)

{

//Printing the elementa

printf("%d\t", arr[i]);

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

arr = it will hold the integer value.

i = it will hold the integer value.
N = it will hold the integer value of the input.

Input number of elements from the user.

Program Logic Code.

Printing output of the program.
