C program to merge two arrays; Through this tutorial, we will learn how to merge two arrays using standard method and function in c programs.
Programs To Merge Two Arrays in C
To merge two arrays using standard method and function in c programs:
- C Program To Merge Two Arrays using Standard Method
- C Program To Merge Two Arrays using Function
C Program To Merge Two Arrays using Standard Method
#include <stdio.h>
print(int *a,int n)
{
int i;
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
int main()
{
int a[10000],b[10000],c[20000],i,n1,n2 ;
printf("Enter size of the 1st array : ");
scanf("%d", &n1);
printf("Enter elements in array : ");
for(i=0; i<n1; i++)
{
scanf("%d",&a[i]);
}
printf("Enter size of the 2nd array : ");
scanf("%d",&n2);
printf("Enter elements in array : ");
for(i=0; i<n2; i++)
{
scanf("%d",&b[i]);
}
for(i=0; i<n1+n2; i++)
{
if(i<n1)
c[i]=a[i];
else
c[i]=b[i-n1];
}
printf(" 1st array :\n");
print(a,n1);
printf("\n2nd array :\n");
print(b,n2);
printf("\nMerged array :\n");
print(c,n1+n2);
return 0;
}
The output of the above c program; as follows:
Enter size of the 1st array : 5 Enter elements in array : 1 2 3 4 5 Enter size of the 2nd array : 3 Enter elements in array : 6 7 8 1st array : 1 2 3 4 5 2nd array : 6 7 8 Merged array : 1 2 3 4 5 6 7 8
C Program To Merge Two Arrays using Function
#include <stdio.h>
merge(int *a,int *b,int *c,int n1,int n2)
{ int i;
for(i=0; i<n1+n2; i++)
{
if(i<n1)
c[i]=a[i];
else
c[i]=b[i-n1];
}
}
print(int *a,int n)
{
int i;
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
int main()
{
int a[10000],b[10000],c[20000],i,n1,n2,n ;
printf("Enter size of the 1st array : ");
scanf("%d", &n1);
printf("Enter elements in array : ");
for(i=0; i<n1; i++)
{
scanf("%d",&a[i]);
}
printf("Enter size of the 2nd array : ");
scanf("%d",&n2);
printf("Enter elements in array : ");
for(i=0; i<n2; i++)
{
scanf("%d",&b[i]);
}
merge(a,b,c,n1,n2);
printf(" 1st array :\n");
print(a,n1);
printf("\n2nd array :\n");
print(b,n2);
printf("\n3rd array :\n");
print(c,n1+n2);
}
The output of the above c program; as follows:
Enter size of the 1st array : 5 Enter elements in array : 1 2 3 4 5 Enter size of the 2nd array : 3 Enter elements in array : 6 7 8 1st array : 1 2 3 4 5 2nd array : 6 7 8 Merged array : 1 2 3 4 5 6 7 8
