Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.

Question

Pointers
Consider the following program:
int a - 3;
int main(void)
int *b = &a;
a- 4;
int a = 6;
int *c = &a;
*C= 7;
int d = *b + *c;
return e;
What integer is in variable d just before main returns?

Question 6 Arrays in c++ can contain different data types (a single array with different data types). O True O False
Write a function getNeighbors which will accept an integer array, size of the array and an index as parameters. This function will return a new array of size 2 which stores the neighbors of the value at index in the original array. If this function would result in returning garbage values the new array should be set to values {0,0} instead of values from the array.

Assume that if 7 consecutive minutes are boring, then an average viewer will stop watching the show. Write a C program that calculates how many minutes that an average viewer will watch a TV show, given the interesting minutes. Assume the TV shows are 45 minutes long. Requirements Name your program project4_minutes.c. Follow the format of the examples below. The program will read in the number of interesting minutes, then read in the interesting minutes. The program should include the following function. Do not modify the function prototype. int find_minute(int *minutes, int n); minutes represents the input array for interesting minutes, n is the length of the array (the number of interesting minutes). The function returns the how…

In C, in order to do operations to the data being referenced by a pointer you would need to use the (*) operator, which is called ______________ operator.
Submerging is the phenomenon wherein the pointer vanishes when you move it too quickly.
TRUE OR FALSE, C++ When passing an array to a function, you must include & in front of the array name. When passing an array to a function, you must include & in front of the array name. It is possible to have a 2-dimensional array where each row has a different number of columns. The * is called the address of operator.
