Hi all!
I have a problem with this code:
it supposed to find the end of array (muzptr), to dynamicaly add another place to it and fill it.
Now muzptr is a dynamic array of a structure type named "music".
Can somebody tell me what's wrong with this code?

	while (!(muzptr[e].makat==NULL)) e++;
		muzptr=(music*) realloc(muzptr, 1*sizeof(music));
			if(muzptr==NULL)			
		{
			perror("Can not allocate memory!");
				exit(1);
		}
		muzptr[e+1]=Muz;

thanx

Your problem is with the size you mentioned in the realloc function. realloc can expand or reduce the allocated size to your pointer. you have asked it to allocate 1*sizeof(music) there. which will give you only 1 unit of structure music. So you are not adding 1 unit to array but actually reducing the size of your array!!!

You have to calculate actual size of your current array and need to add one more unit to it.

say it would be like this.

muzptr=(music*) realloc(muzptr, ((e+1)*sizeof(music)));

I hope this will help you.
