- 7. using c++, Write a void function that accepts an integer array a and a integer SizeA, and an integer n, and adds n to every element in that array. Be sure to develop an appropriate name for your function.c++ the following function header is for a function thattakes two pointers to double-precision, floatingpoint numbers x and y as parameters and does notreturn a value.void exchange( double *x, double y ) Select one: True False1. Inspect the code and in your own interpretation, describe the reason call to functionChangeIt_1(n) will not change x in main()? 2. Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.
- c++, anyone able to help with this, no vectors, no sstream, no pointers, also need a toLower function loop within to account for case insensivity, NEED ASAP pleaseFor C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase. For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become{'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become{'h', 'e', 'l', 'l', 'o', '\0'}
- Need help with a c++ problem, have provided all instructions and code. I have also included the constraints, and you are allowed to use as many if statements and pointers as you want. However, you are only allowed to use one loop. Please write the code in the interQuartile method thank you. PS: Please remember, there is only one loop allowed, so if you chose to use a while loop, you can only use ONE while loop. Cannot use multiple while loops.Inspect the code and in your own interpretation, describe the reason call to function ChangeIt_1(n) will not change x in main()? Inspect the code and in your own interpretation, describe the reason parameter n in ChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? Write a function called void swap with two parameters, which will receive the address of x and y as pointer. The function should swap the value of x and y only if x is larger than y. Print the value of x and y after the function call. Write a function called double getAverage(int *array, int SIZE), where it accept the array as pointer, and return the average of the array. Print the returned value from this function. Always use *array rather than subscript to access the array value.in C Given the code below, what would be the proper way to pass the pointers ptr_1, and ptr_2, to the function mix () defined below? #include <stdio.h> void mix( float *, float * ); int main (void) { float *ptr_1, *ptr_2; mix( ?, ? ) <--- What is the correct way to call the function mix (), and pass the pointer variables ptr_1, ptr_2? return 0; }
- #17a Simple Statistics (not in textbook) Generate a STL array or vector of 1000 floating point numbers in the range 0 to 1. Compute the mean, median, and standard deviation of these. You may use function objects and lambda expressions, and the STL algorithms for_each, accumulate, and sort. You may not use any of the built-in looping constructs while, do-while or for. Also you may not create and use any ordinary c++ functions. Hint: The following code can be used to populate your random array named arr auto arr_store = [](float& v) { v = rand()/float(RAND_MAX); }; for_each(arr.begin(),arr.end(),arr_store); Warning, You may need to know some details about lambda expressions that are not covered in the textbook. These will be covered in the weekly lecture and in a sample program in Sakai resources. Note: The theoretical value of the standard deviation for large N is sqrt(1.0/12) which about 0.289. You should be getting a value fairly close to this.C Programming-Plz fix this code We can return multiple values from functions using pointers. Let's see an example. # include <stdio.h> void add Gr.marks (int * m) { *m = * m + 10; } void main ( ) { int marks; clrscr ( ); printf("enter actual marks:"); scanf(" % d", & marks); add Gr.marks (& marks); printf(" \n the graced marks is :\t % d", marks); }I need help updating function makeMove to do the following in C Programming - Return type void - Parameter list includes i. Pointer to struct Player (i.e. player) ii. 2-d character array (i.e. board), size 8 rows and 8 cols (i.e. use macros ROW and COL) - Update the printf statements to use the struct field playerName- If data validation of length of user input is true (i.e. correct length) set local variable valid equal to function call isValid, pass as arguments i. Array moveii. Array board- Evaluate the value of validi. if false, display to the user their move is invalid ii. if true, display to the user their move is valid This code needs to be updated using the above instructions: void makeMove(char playerName[NAME], int playerNum, char board[ROW][COL]){ char move[THREE]; int valid = FALSE; // loop until the player enters a valid move while(valid == FALSE) { printf("%s, enter your move location (e.g. B6)\n", playerName); scanf("%s", move);…
