Answer #1

If a function needs to return more than one value, as a rule of good programming style, you should change it to a(n) call by reference function and use the appropriate reference parameters to return the values.

Let me give a brief idea about what do we mean by pass by reference function. Instead of passing the value of the variables, we pass the address of the variable in the function, so when the function uses the variable, it goes to the address of the variable and modifies the value of the variable. This is a good technique when we need to manipulate from inside a function the value of an external variable. When we need to return more than one values we pass the reference of the variables and then modify the value at the address, so then more than one values can be returned.

    C programming Write a function that goes through all elements of an array of size n, and output the minimum and maximum values using pointers. Since C functions can only return one value, you must use pointers to output the minimum and maximum values from the function. You are not expected to print the values on the screen. Note: you will be assessed on the functionality and the coding style.

    C++ Programming: Write a function that takes in a C++-style string s (from #include ), as well as an integer n, and then returns true if any substring of length n in s repeats itself, and false otherwise. For example, if s is "toe-to-toe" and n is 3, then the function would return true since "toe" occurs twice within s. However, if n were 4, the function would return false. As a second example, if s is "singing" and n...

    C programming Write a function that accepts an array of integers as an input, and output the sum of all values and the multiplication of all values. e.g. Suppose that the array contained the following values: 1 2 3 -4 5. The function should calculate and output the sum of values (i.e. 1+2+3+(-4)+5=7) and the multiplication of all values (i.e. 1*2*3*-4*5=-120). Start by carefully writing the function prototype - put some thought into this. Think about the good programming habits,...

    MATLAB Create a function that provides a definite integration using Simpson's Rule Problem Summar This example demonstrates using instructor-provided and randomized inputs to assess a function problem. Custom numerical tolerances are used to assess the output. Simpson's Rule approximates the definite integral of a function f(x) on the interval a,a according to the following formula + f (ati) This approximation is in general more accurate than the trapezoidal rule, which itself is more accurate than the leftright-hand rules. The increased...
