In this tutorial you will learn about the C Program to Merge Two Arrays and its application with practical example.
C Program to Merge Two Arrays
In this tutorial, we will learn to create a C program that will Merge Two Arrays using C programming.
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.
- Conditional Statements in the C Programming.
What is Merging?
The merging means is adding two or more arrays into one. Merging can be done with a simple c programming code.
Merging Two Arrays.
In this program, First, we will first take the size of the array from the user. Then we will take the elements of the array from the user. After that, we will add the array into a single array. Then we will print the merged array to the user.
With the help of this program, we can merge Two Arrays in an Array.

// C Program to Merge two arrays. #include <stdio.h> int main() { //declaring the required variables for the program. int n1,n2,n3; //Array Size Declaration //taking the size of the first array. printf("\nEnter the size of first array "); scanf("%d",&n1); //Taking the size of the second array. printf("\nEnter the size of second array "); scanf("%d",&n2); //Merging the size for the third array. n3=n1+n2; printf("\nEnter the sorted array elements"); int a[n1],b[n2],c[n3]; //Array Declaration for(int i=0;i<n1;i++) //Array Initialized { scanf("%d",&a[i]); c[i]=a[i]; } int k=n1; printf("\nEnter the sorted array elements"); for(int i=0;i<n2;i++) //Array Initialized { scanf("%d",&b[i]); c[k]=b[i]; k++; } printf("\nThe merged array..\n"); for(int i=0;i<n3;i++) printf("%d ",c[i]); //Print the merged array printf("\nAfter sorting...\n"); for(int i=0;i<n3;i++) //Sorting Array { int temp; for(int j=i+1; j<n3 ;j++) { if(c[i]<c[j]) { temp=c[i]; c[i]=c[j]; c[j]=temp; } } } //printing the merged array. for(int i=0 ; i<n3 ; i++) //Print the sorted Array { printf(" %d ",c[i]); } return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- n1 = it will hold the integer value.
- n2 = it will hold the integer value.
- n3 = it will hold the integer value.
Taking the size of the array and the elements.
