When asked, "What is a pointer variable?" What should we do now? That's because it's an array that changes on the go. Why are pointers and dynamic arrays problematic?
Given the following code, show step by step and explain how variables are created and eliminated in RAM memory. void p(int& a, float b) { a=1; b=4.0f; } int main(void) { float a=3; int c=4; p(c,a); }
Complete the tables that follow to describe the memory addresses and values of each variable when the last statement in the ChangePasscode function is performed (right before the function exits). Note: Operating systems may use different rules for assigning memory addresses. For this worksheet let us assume that the compiler will use up the greater memory address first (e.g., if 0x7ffd151a1d58 and 0x7ffd151a1d5c are available, it will initialize variables in 0x7ffd151a1d5c first).

Assembly language Part 1: When a variable is stored in memory, it is associated with an address. To obtain the address of a variable, the & operator can be used. Write a C program addressOfScalar.c by inserting the code below in the main function. Questions: 1) Run the C program, attach a screenshot of the output in the answer sheet. 2) Attach the source code in the answer sheet 3) Then explain why the address after intvar is incremented by 4 bytes instead of 1 byte.
QUESTION 17 If program code references an invalid array index value, when is an error message generated? a. An error occurs during execution. b. An error occurs when the program is compiled. c.
