C Programming code for Merging of Two 1D Arrays – KLE Tech

Write a Modular C Programming Code for Merging of Two 1D Array?

CODE:

#include<stdio.h>
void readArray(int[],int);
void merge(int[],int[], int , int );
void readArray(int[],int );
int main()
{
int n1,n2;
int arr1[100], arr2[100];
printf("Enter the size of 1st Array: ");
scanf("%d",&n1);
printf("Enter the elements of 1st array: \n");
readArray(arr1,n1);
printf("Enter the size of 2nd Array: ");
scanf("%d",&n2);
printf("Enter the elements of 2nd array: \n");
readArray(arr2,n2);
merge(arr1,arr2,n1,n2);

}
void readArray(int arr[],int n)
{
int i;
for(i=0;i<n;i++)
{
scanf("%d",&arr[i]);
}
}
void displayArray(int arr[],int n)
{
int i;
for(i=0;i<n+1;i++)
{
printf("%d ",arr[i]);
}
}
void merge(int arr1[], int arr2[], int n1, int n2)
{
int n3, i, j;
n3 = n1 + n2;
int c[n3];
for(i = 0; i < n1; i++)
{
c[i] = arr1[i];
}
for(i = 0, j = n1; j < n3 && i < n2; i++, j++)
{
c[j] = arr2[i];
}
printf("\n arr[%d] Array Elements After Merging \n", n3);
for(i = 0; i < n3; i++)
{
printf(" %d \t ",c[i]);
}
return 0;
}

OUTPUT

Enter the size of 1st Array: 5
Enter the elements of 1st array:
1
2
3
4
5
Enter the size of 2nd Array: 5
Enter the elements of 2nd array:
6
7
8
9
10

arr[10] Array Elements After Merging
1 2 3 4 5 6 7 8 9 10
