Question

Can anyone explain what I’m doing wrong here to not get 11 as my output?

void foo {
    int *n = malloc(sizeof(int)); 
    *n = 10; 
    n++;
    printf("%d", *n)
}

Answer 1

n++ increments the pointer n, not the integer pointed to by n. To increment the integer, you need to dereference the pointer and then increment the result of that:

(*n)++;
