Write a function   void RotateLeft(int A[ ], int n, int x). which will rotate the elements of array A towards the left by x number of positions. Assume that x > 0.

Declare 2D array whose size and elements must be according to the desire of user then perform the following functions on it Display a lower triangular matrix. Find the sum of an upper triangular matrix. DO IT IN C++

C language

Write a C++ program that computes for the sum, difference, product, and quotient of two floating-point numbers with two decimal places in the quotient.

For this c++ assignment it must pass the test input as shown below

Consider the following program that reads students’ test scores into an array and prints the contents of the array.   You will add more functions to the program.  The instructions are given below. For each of the following exercises, write a function and make the appropriate function call in main. Comments are to be added to the program.   Write a void function to find the average test score for each student and store it in an array studentAvgs.   void AverageScores( const int scores[][MAX_TESTS],                        int numberOfStudents,                        int numberOfTests,                        double studentAvgs[]);   2.  Write a void function to find the average score on each test and store in an array testAvgs.     3. Write a void function to print the average score for each student, i.e. print the contents of the array studentAvgs. The output will be well formatted and accompanied with appropriate messages. 4. Write a void function to print the average score on each…

In C++,  Can you please look at the code below and revise/fix so it will work according to instructions and criteria. Instruction 1) Write a function that copies a 1D array to a 2D array. The function’s prototype is bool copy1DTo2D(int d1[], int size, int d2[][NCOLS], int nrows); where size > 0 NCOLS > 0 nrows > 0 NCOLS is a global constant size = NCOLS * nrows the function returns true if the parameters and constants satisfy these conditions and false otherwise. the relation between 1d array indices and 2d array indices is 2d row index = 1d array index / NCOLS 2d column index = 1d array index modulus operator NCOLS   2) Write a function that copies a 2D array to a 1D array. The function’s prototype is bool copy2DTo1D(int d2[][NCOLS, int nrows, int d1[], int size); where size > 0 NCOLS > 0 nrows > 0 NCOLS is a global constant the function return true if the parameters and constants satisfy these conditions and false otherwise. the relation between 1d array indices and…
