CSC209H1 Lecture Notes - Lecture 5: C Dynamic Memory Allocation, Call Stack
Document Summary
Csc209h worksheet: malloc basics: each time a variable is declared or memory is otherwise allocated, it is important to understand how much memory is allocated, where it will be allocated and when it will be de-allocated. Complete the table below. (note: some of the programs allocate more than one block of memory. ) *i = malloc(sizeof(int)*7); int main() { int *i; fun(&i); free(i); int sireofcia v int.

We have set up both stack frames for you, and the location of the heap. Heap stack frame for initialize stack frame for main numbers"t.
