Write a short C program that declares and initializes (to any value you like) a double, an int, and a char. Next declare and initialize a pointer to each of the three variables. Your program should then print the address of, and value stored in, and the memory size (in bytes) of each of the six variables. Use the “0x%x” formatting specifier to print addresses in hexadecimal. You should see addresses that look something like this: "0xbfe55918". The initial characters "0x" tell you that hexadecimal notation is being used; the remainder of the digits give the address itself. Use the sizeof operator to determine the memory size allocated for each variable. */

Write a C program that uses the following: a main() to read two integer values from the user, val1 and val2, and prints the returned value from swap().a swap() that uses call by reference (takes the addresses into pointers) to swap values, and prints their values after the swap "num1 = # and num2 = #". This function returns the largest of the two values. If these are equal, it returns their sum.
Write a program C++ to add four float numbers & print the address and subtraction using pointers?
In C, write a function that gets 3 pointers int* a, int* b, int* c, and rotates the values in their addresses to the left. That is, a gets the value of b, b gets the value of c, and c gets the value of a. void rotate3 (int* a, int* b, int* c); For example, if we have int x=1, y=2, z=3, then after calling rotate3 (&x, &y, &z) we should have x==2, y==3, and z==1. if we have int x=7, y=1, z=6, then after calling rotate3 (&x, &y, &z) we should have x==1, y==6, and z==7.
Using only getchar from stdio.h along with the standard operators, create a program in c language where: -Initialize a multidimensional array words, where the size of the first dimension is MAXWORDS and the size of the second dimension is MAXLEN. -Write lines of code which takes an input stream of characters (max of 1000 characteres) from the user using getchar, until the user triggers the end of file.-Create three arrays of pointers p1[], p2[], p3[], where each element of these arrays point to a string.
. What will be the output of the following code, consider the memory address of variable x is 0x0044c and pointer variable ptr is 0x0066f, and consider int data type take 2 byte in the memory void main() { int x[5] = { 1,2,3,4,5 }; int *ptr = x; ptr = ptr + 1; cout << ptr << endl; cout << *ptr << endl; cout << &ptr << endl; cout << &x[0] << endl; cout << *x << endl; x += 2; cout << x << endl; }
Use the C programming language to write code that proclaims and sets a double, int, and char. Afterward, proclaim and set a pointer to the double, int, and char. The code must print the inscription of, and value stored in, and the memory size (in bytes) of all six variables. The "0x%x" formatting specifier outputs inscriptions in hexadecimal. SAMPLE OUTPUT: Char ___ 's inscription is 0x___Int ___'s inscription is 0x___Double ___'s inscription is 0x___Char* ___'s inscription is 0x___Int* ___'s inscription is 0x___Double* ___'s inscription is 0x___Char ___ 's value is ___Int ___'s value is ___Double ___'s value is ___Char* ___'s value is 0x___Int* ___'s value is 0x___Double* ___'s value is 0x___Char ___ 's size is ___ bytesInt ___'s size is ___ bytesDouble ___'s size is ___ bytesChar* ___'s size is ___ bytesInt* ___'s size is ___ bytesDouble* ___'s size is ___ bytes
4) Answer the question in C++ A) What is wrong with the following code segment? enum CarType {GM, FORD, BMW}; int main() { CartType = BMW; return 0; } B) Assume that the addresses of x and y is 0x61feb8 and 0x61feb0, respectively. What will be the values of x, y, p, and q, respectively, when the following code runs successfully? int main() { int x; double y; int* p = &x; double* q = &y; *p = 3; *q = 3.14; increaseByOne(p, q); cout << x << " " << y << endl; cout << p << " " << q << endl; return 0; }void increaseByOne(int*& p1, double* q1){ (*p1)++; (*q1)++; p1++; q1++;} The four value:
Write a program in HACK assembly, without using symbols, that sums the consecutive set of memory locations starting from the memory address stored in RAM[1]up to, but not including, the memory address RAM[1] + RAM[2]. The result of thecomputation should be stored in RAM[0]. Note, you need not consider the case ofan overflow.You can think of RAM[1] as being a pointer to an array of numbers, and RAM[2] asbeing the length of the array you are summing over.
Write a program to find the number of times that a given word occurs in a sentence using pointers. Read data from standard input. The first line is a single word, which is followed by general text on the second line. Read both up to a new line character, and insert a terminating null before processing. Typically output should be : The word is “ the ”. The sentence is “ the cat on the mat “ . The word occurs 2 times.
The program below uses pointer arithmetic to determine the size of a 'char'variable. By using pointer arithmetic we can find out the value of 'cp' and thevalue of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic:adding one to a pointer makes the pointer point to the next element of the sametype.For a pointer to a char, adding 1 really just means adding 1 to the address, butthis is only because each char is 1 byte.1. Compile and run the program and see what it does.2. Write some code that does pointer arithmetic with a pointer to an int anddetermine how big an int is.3. Same idea – figure out how big a double is, by using pointer arithmetic andprinting out the value of the pointer before and after adding 1.4. What should happen if you added 2 to the pointers from exercises 1through 3, instead of 1? Use your program to verify your answer.
