﻿ C : Take the values before the element value 5 from an array

# C Exercises: Create a new array taking the elements before the element value 5 from a given array of integers

## C-programming basic algorithm: Exercise-69 with Solution

Write a C program to create a new array taking the elements before the element value 5 from a given array of integers.

C Code:

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

// Function prototype for 'print_array'
void print_array(int parray[], int size);

int main(void){
int arr_size;

// Declaration and initialization of an integer array 'a1'
int a1[] = {1, 2, 3, 5, 7};
arr_size = sizeof(a1)/sizeof(a1[0]);

// Printing the elements of the original array 'a1'
printf("Elements in original array are: ");
print_array(a1, arr_size);

// Declaration of 'size' variable and an integer array 'pre_ele_5'
int size = 0;
int pre_ele_5[arr_size];

// Loop to find the position of the first occurrence of 5 in 'a1'
for (int i = 0; i < arr_size; i++)
{
if (a1[i] == 5)
{
size = i;
break;
}
}

// Declaration and initialization of 'result' array using the 'size' variable
int result[size];

// Loop to copy elements from 'a1' to 'result' up to the position of the first 5
for (int j = 0; j < size; j++)
{
result[j] = a1[j];
}

// Updating 'arr_size' to reflect the size of the 'result' array
arr_size = sizeof(result)/sizeof(result[0]);

// Printing the elements of the new array 'result'
printf("\nElements in new array are: ");
print_array(result, arr_size);
}

// Definition of the 'print_array' function
void print_array(int parray[], int size)
{
int i;
// Loop to print the elements of the array
for( i = 0; i < size - 1; i++)
{
printf("%d, ", parray[i]);
}
// Printing the last element
printf("%d ", parray[i]);
printf("\n");
}
``````

Sample Output:

```Elements in original array are: 1, 2, 3, 5, 7

Elements in new array are: 1, 2, 3
```
