@Alam, Try this revised code
#include<stdio.h>
#include<conio.h>
int array3[10];
main()
{
clrscr();
int *take,i;
int array1[10]={1,2,3,4,5,6,7,8,9,10};
int* modify(int*);
take=modify(array1);
for(i=0;i<10;i++)
printf("%d ",*(take+i));
getch();
}
int* modify(int* array2)
{
int i;
for(i=0;i<10;i++)
{
array3[i]=3*array2[i];
// printf(" %d",array3[i]);
}
return array3;
}
