Write a C++ function void rect (int& ar, int& per, int len, int wid) that computes the area ar and perimeter per of a rectangle with length len and width wid. Test it inside the main program that inputs the length and width of a rectangle and outputs its area and perimeter. Output the value in the main program, not in the procedure.

*You need to have at least one user define function *Language: C programming  Write a C Program to print half pyramid using numbers shown below. This example is for height 6. Ask user for a height and depending on user input, draw the half pyramid.   Input: Key in the height: 6 Output: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6

The following program will prompt the user for a starting number and an // ending number. Assume that these are whole numbers (no decimal points), // assume the numbers are not negative and assume that the first number is // not larger than the second number. // // write a funcTion that returns the sum of the numbers from the starting // number to the ending number. For example, if the starting number is 13 // and the ending number is 18 then the function will return the value of // 13 + 14 + 15 + 16 + 17 + 18. If the starting number is equal to the ending // number then simply return that number. // //////////////////////////////////////////////////////////////////////////   function sumOfNumbers(startingNumber, endingNumber) {     } var startingNumber = parseInt(prompt('What is the starting number?
