In this tutorial, i am going to show you how to copy the elements present in one array to another using for loop, function and recursion in c programs.
All C Programs to Copy an Array to another
- C Program to Copy an Array to another using For Loop
- C Program to Copy an Array to another using Function
- C Program to Copy an Array to another using Recursion
C Program to Copy an Array to another using For Loop
/* c program to copy one array to another array */
#include<stdio.h>
int main()
{
int i, Size, a[20], b[20];
printf("\n Please Enter the Array Size :- ");
scanf("%d", &Size);
printf("\n Please Enter the Array Elements :- ");
for(i = 0; i < Size; i++)
{
scanf("%d", &a[i]);
}
/* copying one array to another */
for(i = 0; i < Size; i++)
{
b[i] = a[i];
}
printf("\n Elements of Second Array are: \n");
for(i = 0; i < Size; i++)
{
printf("\n Value Inside Array b[%d] = %d", i, b[i]);
}
return 0;
}
The result of the above c program; as follows:
Please Enter the Array Size :- 5 Please Enter the Array Elements :- 1 2 23 4 5 Elements of Second Array are: Value Inside Array b[0] = 1 Value Inside Array b[1] = 2 Value Inside Array b[2] = 23 Value Inside Array b[3] = 4 Value Inside Array b[4] = 5
C Program to Copy an Array to another using Function
#include <stdio.h>
copy(int *a,int *b,int n)
{
int i;
for(i=0; i<n; i++)
{
b[i]=a[i];
}
}
print(int a[],int n)
{ int i;
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
int main()
{
int a[1000],b[1000],i,n;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d", &a[i]);
}
copy(a,b,n);
printf(" first array : ");
print(a,n);
printf("\nsecond array : ");
print(b,n);
}
The result of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 5 6 1 4 8 first array : 5 6 1 4 8 second array : 5 6 1 4 8
C Program to Copy an Array to another using Recursion
#include <stdio.h>
copy(int a[],int b[],int n,int i)
{
if(i<n)
{
b[i]=a[i];
copy(a,b,n,++i);
}
}
print(int a[],int n)
{ int i;
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
int main()
{
int a[1000],b[1000],i,n;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d", &a[i]);
}
copy(a,b,n,0);
printf(" first array : ");
print(a,n);
printf("\nsecond array : ");
print(b,n);
}
The result of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 1 3 5 4 8 first array : 1 3 5 4 8 second array : 1 3 5 4 8
