it grows toward address zero; on some other architectures, it grows in the opposite direction. A “stack pointer” register tracks the top of the stack; it is adjusted each time a value is “pushed” onto the stack. The
Memory Layout of a C Program A typical memory representation of C program consists of following sections. 1. Text segment2. Initialized data segment 2.1 initialized read-only area 2.2 initialized read-write area3. Uninitialized data segment4. Heap5. Stack Read Memory Layout of C Programs for ...
