@Amit Jaspal...there is a fundamental error in the code related to pointers....u have incremented the pointers p and x..so before the printf loop, pointer p (as well as x) is pointing to 4th location...I hope I am clear...
this can be done by creating two more pointers that will initialised as the base location of p and x... #include <stdio.h> int main(){ int *p,*a,i=0; void *x,*b; p=(int *)malloc(3*sizeof(int)); * a =p;* x=malloc(24); * b = x;* p[0]=1; p[1]=2; p[2]=3; p[3]=4; while(i<4){ *((int *)x)=*p; ((int *)x)++; p++; i++; } for(i=0;i<4;i++){ *printf("%d\n",a[i]); printf("%d\n",((int *)b)[i]);* } system("pause"); return 0; } On Sun, May 29, 2011 at 11:38 PM, amit <amitjaspal...@gmail.com> wrote: > Suppose I want to copy an integer array to another array pointed by a > void pointer of different size. > Some thing like this is done probably in realloc function. > > The problem is it is not working for me ... here's the code > > #include <stdio.h> > int main(){ > > int *p,i=0; > void *x; > p=(int *)malloc(3*sizeof(int)); > x=malloc(24); > p[0]=1; > p[1]=2; > p[2]=3; > p[3]=4; > while(i<4){ > *((int *)x)=*p; > ((int *)x)++; > p++; > i++; > } > > for(i=0;i<4;i++){ > printf("%d\n",p[i]); > printf("%d\n",((int *)x)[i]); > } > return 0; > } > > > Can anyone suggest what is happening wrong in this code.....or what > can be a better way to do this. > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algogeeks@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > > -- *Piyush Sinha* *IIIT, Allahabad* *+91-8792136657* *+91-7483122727* *https://www.facebook.com/profile.php?id=100000655377926 * -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
