these strings are stored in a variable "str"

------------ --------- --------- ---
I want to know why garbage values are being printed..... .........
------------ --------- --------- ----here is the code ------------ --------- -
#include<stdio. h>
char* call()
{
int k=3,h=0;
char *str[3];
for(h=0;h<k; h++)
{
printf("Enter the String");
scanf("%s",str+ h);
}
return *str;
}
int main()
{
int i=3,j=0;
char name[i][20];
name[0]=call( );
for(j=0;j<i; j++)

Adding to Nico's observations. Isn't the variable declared locally?
So it should return garbage anyhow after returning, since no form of memory
allocation is done for the strings. As the memory allocated for the variable
might be reused, giving garbage output.
