Write a C++ program for the following In this task, your job is to create a function Swapper() that takes three arguments num1,num2, and difference. The first argument should be passed by pointer, second argumentshould be passed by reference, and third argument should be passed by value. YourSwapper function should first swap the values of num1 and num2 with each other, andthen compute the difference of most significant digits of both numbers. You have to storethe difference result in difference variable. In the end, you need to display the values ofall three variables inside your Swapper method as well as in your main function.Note: You are not allowed to create any other variable or pointer inside your Swappermethod.
Write a C program to swap two integers you should write a function named as swap_intand it should accept arguments as pointers then it should swap integers bydereferencing those pointers.
Write a C++ program for the following Create a function Display() and declare four variables and four pointers of types int,char, double and float in it. You can initialize the variables with any values of yourchoice. After variable initialization, assign addresses of those variables to thecorresponding declared pointers. At the end, you need to print the following values• values stored in all variables• values stored in pointers• addresses of all the variables• addresses of all the pointers• sizes of all the variables• sizes of all the pointers
Write a C program that includes the following: Has 2 functions: main and swap. swap will receive two integer pointers and swap the integer values using these pointers main will have 2 integers a = 5 and b = 2 main will call swap so that a becomes 2 and b becomes 5 main will display the value of a and b both before and after the swap.
When a variable is stored in memory, it is associated with an address. To obtain the address of avariable, the & operator can be used. For example, &a gets the memory address of variable a.Let's try some examples.Write a C program addressOfScalar.c by inserting the code below in the main function. 1 // intialize a char variable, print its address and the next address2 char charvar = 'a';3 printf("address of charvar = %p\n", (void *)(&charvar));4 printf("address of charvar - 1 = %p\n", (void *)(&charvar - 1));5 printf("address of charvar + 1 = %p\n", (void *)(&charvar + 1));67 // intialize an int variable, print its address and the next address8 double doublevar = 1.0;9 printf("address of doublevar = %p\n", (void *)(&doublevar));10 printf("address of doublevar - 1 = %p\n", (void *)(&doublevar - 1));11 printf("address of doublevar + 1 = %p\n", (void *)(&doublevar + 1)); Questions:1) Run the C program, attach a screenshot of the output in the answer…
Write a C program that uses a function to calculate Rt. The user will be prompted to enter R1, R2 & R3 which will be passed to the function as parameters, do not use global variables or pointers. The values have no specified range for them but if any of the 3 inputs are less than 0, the function should return 0. The main function should then display the calculated value of Rt with 2 decimal places or an appropriate error message. (Do not use printf or scanf inside the function ... all input/output should be in main) Use appropriate message to prompt the user to enter each value. Three resistors (R1, R2 and R3) are connected so that R1 & R2 are in parallel then in series with R3. Their equivalent resistance (Rt) is calculated using the following equation: Rt=(R1xR2/R1+R2)+R3
Part 2:Write a C program addressOfArray.c by inserting the code below in the main function. 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.
Write a C function that is given a pointer to memory, the number of bytes of memory the pointer points at, and two pointers to uint32_t. Your job is to treat the pointer as if it were a pointer to an array of uint32_t, find the min and max values of the array, and write the results to the locations pointed at by the uint32_t pointers. The number of bytes will be a positive multiple of 4. Do not worry about endianess in this problem. Note the tester has command line options -Wall -Wextra -Werror -fsanitize=address to help you catch errors.
Write a complete C++ program that asks the user to input two floating-point numbers (i.e., base, perimeter ). There is a function named side that accepts two floating-point numbers as a parameter and returns one value of type float. The function calculates and returns the side of the parallelogram if the base and perimeter are positive otherwise this function will return zero. Then your C++ program will allow the user to input two float values to pass them on the side function. Then the program will display the value return from this function. (Hint: side of the parallelogram is .
Q) Write a program C++ to exchange the value of x from K to Y then print the address and value before and after exchanging using Pointers to functions? *
A programmer implemented a swap function in C as follows: void swap(int x, int y) { int temp; temp = x; x=y; y = temp; } However when he tried to use the swap function in the main function as given below, it didn’t work. int main () { int a=10, b=20; swap(a,b); ... } i. Explain why this function doesn’t work. ii. Suggest a way of fixing it.
Write a C++ program that asks your if he wants to store student’s data such as name, id (20i-xxxx) andaddress. Your program should be able to store data for any number of student but, efficiently utilizingthe memory.Your program must have the following function.1) TakingInput: Takes input from user regarding student name, id and address.2) StoringData: Data from TakingInput is then passed to this function where it(data) is stored in adata structure.
