- USING FILE POINTERS IN C PLEASE . Write a program that prints a table of all the Roman numeral equivalents of the decimal numbers in the range 1 to 50. Knowing that the roman numbers (from 1 to 10) are as follows: I, II, III, IV, V, VI, VII, VIII, IX, X. Note that 50 is represented by L. COMMENT ALL OF YOUR STEPSIn C programming. How do I find the max and min values of the corressponding columns. #include <stdio.h>#include <math.h>#include <stdlib.h>#define NROWS 5#define NCOLS 5 int main(void){ int i,j, max, min, m, n; float M[NROWS][NCOLS], Mt[NROWS][NCOLS]; char key_hit; //Input the sizes printf("ROW size(1-5) : ");scanf("%d",&m); printf("Column size(1-5): ");scanf("%d",&n); //Size Check while(m>NROWS || n>NCOLS) { printf("Please re-enter the sizes. \n"); printf("Row size(1-5) : ");scanf("%d", &m); printf("Column size(1-5) : ");scanf("%d", &n); } //Input the Matrix Data for(i=0; i<m; i++) for(j=0; j<n; j++) { printf("M[%d][%d] = ", i,j); scanf("%f", &M[i][j]); } //Print the Matrix Data for(i=0; i<m; i++) { for(j=0; j<n; j++) { printf("%1.2f\t", M[i][j]); }…Look at the following C++ code and comment each line about how it works with pointer. int i = 33; double d = 12.88; int * iPtr = &i; double * dPtr = &d; // iPtr = &d; // dPtr = &i; // iPtr = i; // int j = 99; iPtr = &j; //
- (Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.a. Write a statement that declares votes to be pointer of type int. b. Write a C++ code that dynamically creates a two-dimensional array of 50 rows and 10 columns and votes contains the base address of that array. c. Write a C++code that outputs the data stored into the array votes one row per line. d. Write a C++ code that deallocates the memory space occupied by the two-dimensional array to which votes points.For the below example: In which memory segments are the variables in the following code located? int i = 0; void func(char *str) { char *ptr = malloc(sizeof(int)); char buf[1024]; int j; static int y; }
- What is pointer? Write a program that inputs three integers from thekeyboard and prints the sum, average, product, smallest and largest of thesenumbers. The screen dialogue should appear as follows:C++ Language Write two statements that each use malloc to allocate an int location for each pointer. Sample output for given program:numPtr1 = 44, numPtr2 = 99 #include <stdio.h>#include <stdlib.h> int main(void) { int* numPtr1 = NULL; int* numPtr2 = NULL; /* Your solution goes here */ scanf("%d", numPtr1); scanf("%d", numPtr2); printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2); free(numPtr1); free(numPtr2); return 0;}Write a function that uses a pointer to copy an array of size n. The data type of the array should be double. You can take input from the user, or you can use random variables. 6. Write a function that will receive a pointer to an array of floats of length n. The function will return the address of the maximum value in the array. need the solve in c++ language
- write a single statement that performs the specified task. Assume that long variables value1 and value2 have been declared and value1 has been initialized to 200000 ."Assign the address of variable value1 to pointer variable longPtr .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…Please help me make memory diagrams for points one, two and three in the program. I dont know how to do so and I need to understand, also please explain what youre doing as youre solving /* An exercise to help you understand the use of pointer variables. */ #include <stdio.h> int main(void){ int foo; int bar; int *fred; int *sam; bar = 100; foo = 200; fred = &foo; /* point one */ printf("point one: foo is %d and bar is %d.\n", foo, bar); sam = &bar; *sam += 30; *fred -= 40; /* point two */ printf("point two: foo is %d and bar is %d.\n", foo, bar); fred = &bar; *fred += 5; /* point three */ printf("point three: foo is %d and bar is %d.\n", foo, bar); printf("point three: *fred is %d and *sam is %d.\n", *fred, *sam); sam = &foo; *sam = *fred; /* point four */ printf("point four: foo is %d and bar is %d.\n", foo, bar); *sam *= 100; sam = fred; /* point five */ printf("point five: foo is %d and bar is %d.\n", foo, bar);…
