I think the answer in B

random comment for engagement

i have a test on tuesday about this subject and you helped me a lot on learning it. i really hope that more and more people will be helped by this and the other videos of yours. God bless y'all and thx for the great content :D

amazing teacher😍

# include <stdio.h>

int main(){

int n = 4;

int* ages;

ages = (int*)malloc(n* sizeof(int));

if(ages == NULL){
printf("Memory cannot be allocated");
return 0;
}

printf("Enter input value\n");
for(int i = 0; i < n; ++i){
scanf("%d",ages + i);
}

n = 6;

ages[4] = 32;
ages[5] = 59;

ages = realloc(ages,n* sizeof(int));

printf("Input value\n");
for(int i = 0; i < n; ++i){
printf("%d\n",*(ages + i));
}

free(ages);

return 0;
}

Thanks!!!

helped a lot. thanks

As a new C/Cpp user: I wonder any way or plugin in Vscode which can help me to detect the unused heap list or warn me that the heap list should be deleted or freed(just like the GC in java and python)

Thanks for the video, it helped a lot!

I'm getting a warning for ptr = realloc(ptr, n * sizeof(int)); saying that realloc could return NULL, which "will cause the original memory block to be leaked", any know how to fix this?

gud

Great video

You are doing an amazing job . I have learned alot

Quiz answer should be B

Madam please what about calloc?

When i run the realloc() code in visual studio code it returns an error as its expecting a void data type yet the malloc() worked.
Can anyone 'point' me in the right direction?

Thanks

int *ptr, i , n1, n2; 
ptr = (int*) malloc(n1 * sizeof(int));
ptr = realloc(ptr, n2 * sizeof(int)); // error expecting void type in ptr ?

best for beginner💓

mam u r so pretty 😍

nice
