Does anyone know any good resources for learning to prevent memory and pointer based errors?

Can anyone tell me what the line 22 of this code is going ? Tried searching for it in google but could not get the answer

Meme or fr?

Online sources for static and dynamic memory allocation?

I looked and the code does not have correct braces, but what she said should be right after the code is corrected

any study book on C or C++ will do.

Here is the simple code #include <stdio.h> #include <stdlib.h> /* required for the malloc and free functions */ int main() { int number; int *ptr; int i; printf("How many ints would you like store? "); scanf("%d", &number); ptr=malloc(number*sizeof(int)); /* allocate memory */ if(ptr!=NULL) { for(i=0 ; i<number ; i++) { *(ptr+i) = i; } for(i=number ; i>0 ; i--) { printf("%d\n", *(ptr+(i-1))); /* print out in reverse order */ } free(ptr); /* free allocated memory */ return 0; } else { printf("\nMemory allocation failed - not enough memory.\n"); return 1; } }

The best way to avoid most mistakes is by using smart pointers. Also, good static analyzers (clang-tidy) and profiling tools (valgrind) can help you prevent most memory bugs

Is this indian?

Well, most books I've seen provide a basic intro to pointers and that certainly doesn't help when you just can't figure out the segmentation faults 😝

You could try to use a book on pointers like "Understanding and Using c pointers"

Indian is not a language..

Amean Hindi

No, it's just a pun write=right

I found a good book for understand point,named "Computer Systems: A Programmer's Perspective"

So?

Can any of the admin point please out how to enable the 'click to prove you're a human' option of @MissRose_bot ? It's for another group.

The last 3 in the few minutes all seem like Europeans. Maybe someone shared our group

Hi! In C# we use lambdas as a inline functions to do something immediately, is there a way to invoke lambda immediately in c++?

The 5 may be because of 5 fixed nodes in the tree, the rest of the nodes depend on the length of the string

Yes

When we push_back, an object is created whose copy is actually inserted into the vector. Does that happen for primitive datatypes too?

No

Between push_back and what?

No difference after optimization for vector

after opti? what does that mean?

Will be different e.g. for map

diff for map? push_back isn't for maps. so why does diff. comes in first place?

And I don't understand why people ask silly questions which they could make a small program online and check.

Diff was presented because question was about push_back, not vector::push_back
