Programming & Computer Science Answers

1. Write a C++ program that will create 2D array using random numbers and then show these values.

1. Write user defined function arrayFunction() in C++ which will initialize array by taking values from user at run time and then call this function in main function which will return this array from the calling function to the called function (to the main function) and then show all items of this array in main function using loop.

Make a calculator using if-else-if else statement which perform the addition, subtraction, multiplication, division and remainder operations. Take values and operator from user on runtime. Use do while loop for user choice. Means after performing one operation program will ask from user “do you want to do another calculation(yes/no)? ”. If user press then user will enter number 1, number 2 and operator for calculation and if user press no then terminate the loop.

Update your calculator using functions (Calculator you implemented in do while loop .Create separate functions for addition, subtraction, division, multiplication and remainder operations).

1. Write function in C++ that will find factorial of a number. Number must be passed from calling function as an argument to function parameters.

Write function in C++ that will calculate table of a number in C++. Number must be passed from calling function as an argument to function parameters.

1.  Write a program that check the type of the value and determine the data type of the value. In this program, you will develop a Type checking program (Type Checker).

If the argument of printType(true) is true or false, it will invoke a function inside and print a message “true is a boolean”. If it is int 463287462 then it should display “4632874 is Integer”. The sample output format is as follows:

1.24353 is double data type 334345345 is an integer data type 1 is boolean data type

A is a character data type

print an inverted pyramid by using for loop structure and 'setw' manipulator.

print a pyramid by using "setw" manipulator in C++

If user press then user will enter number 1, number 2 and operator for calculation and if user press no then terminate the loop.

Take a number from user and make a multiplication table of that number till 10

using do while loop.
