HI, I am running the following peice of code on Dev-cpp compiler
#include<stdio.h>
#include<stdlib.h>
#include<stddef.h>
struct bst
{
int info;
struct bst *leftnode;
struct bst *rightnode;
};
void insert(struct bst *node,int val1)
{
struct bst *newnode=malloc(sizeof(struct bst));
struct bst *temp=malloc(sizeof(struct bst));
newnode->info=val1;
temp=node;
while(temp)
{ printf("\n Inside while loop");
* if(val1<=temp->info)*
if(temp->leftnode!=NULL)
{ temp=temp->leftnode;
printf("\n IN if of left");
}
else
break;
else
if((temp->rightnode)!=NULL)
{ temp=temp->rightnode;
printf("\n IN if of right");
}
else
break;
}
if(!temp)
{ free(temp);
return;
}
else if(val1<=temp->info)
{ temp->leftnode=newnode;
printf("\n Inserted to the left");
}
else
{ temp->rightnode=newnode;
printf("\n Inserted to the right");
}
newnode->leftnode=NULL;
newnode->rightnode=NULL;
free(temp);
}
int main()
{
struct bst *start=malloc(sizeof(struct bst));
// struct bst *newnode=malloc(sizeof(struct bst));
start->info=10;
start->leftnode=NULL;
start->rightnode=NULL;
printf("Data is :%d",start->info);
getchar();
insert(start,20);
* insert(start,5);*
getchar();
free(start);
return 0;
}
The compiler reports *Access violation* at the highlighted lines i.e.
*insert(start,5);*
But at the run of insert(start,20); , there is no problem as such.
Please help !!
Regards
Puneet
