Write, compile and run a C++ program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 75, 82 and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main()

Discussion: Files with .h extension are called header files in C. These header files generally contain function declarations which we can be used in main C program, like for e.g. to include stdio.h in C program to use function printf() Exercise 1. C-Program to Create your own Header File Step 1 : Type this Code int add(int a,int b) { int sum; sum= a+b; return sum; } In this Code write only the function definition as you write in General C Program Step 2 : Save Code Save Above Code with [.h ] Extension . Let the name of our header file be myhead [ myhead.h ] Compile Code if required. Step 3 : Write Main Program #include<stdio.h> #include"myhead.h" int main() { int num1 = 10, num2 = 10, num3; num3 = add(num1, num2); printf("Addition of Two numbers : %d", num3); } Instead of writing < myhead.h>; use this terminology “myhead.h” All the Functions defined in the myhead.h header file are now ready for use . Directly call function add(); [ Provide proper…
In C++, Write a function named that accepts argc and args with the same data type as command line arguments (int argc, char * args[]). It will return two boolean values. It checks whether each of command line argument ending with a comma (‘,’) or not. If they all are, it will return true. Otherwise, it returns false. It will also return true if there is no argument is given. In addition, it also returns another boolean flag indicating whether one of the arguments is just a comma only.For this question, you are not allowed to use string class and its method or string function such as strlen.
Computer Science In C++ use the following STL algorithms: reverse, rotate, and shuffle. Write versions of these functions using the same parameters as the original functions but using your own definition of the function body. Use each function at least three different times in a test program to make sure the function operates properly. The data sets you use for testing should contain at least twenty elements
In C++, If you had the double-pointer above and also had these variables: type x, * q; And had executed these statements: q = &x; p = &q; How would a function given p by value be able to change the contents of x?
Write a program in C++, which has a function to swap/exchange elements of two arrays of type float of size N each. Function is passed pointers of the arrays and their size for processing. Inside the function, use pointer to access elements of arrays. Your program should have the followings: Prototype of the function Definition of the function Two arrays discussed above are declared and initialized in the main() function. Do not take input from keyboard. Call function from main() to exchange elements of arrays Display elements of arrays before and after calling functions
Write a C++ function definition named containsNumber. The function should take three parameters: a one-dimensional integer array, the number of entries in the array, and an integer value. The function should search the array for the integer value and return a boolean value of true if the value is found and false otherwise. Below is a example call to the function: valueFound = containsNumber(table, nbrOfEntries, value); You may assume that all parameters passed to the function are valid, that the nbrOfEntries amount is always greater than or equal to one, and that a specific integer value occurs at most once in the table. Remember to only write the function definition for the containsNumber function. Do not write a complete C++ program.
In C++, Write a complete program to call a function that swaps the values stored in two variables. The function accepts two parameters x and y which are to be swapped. The parameters can be of any data-type.
Write a function in C++ called maximumGap that finds the maximum difference between corresponding entries in two arrays (that have the same capacity). There are 3 parameters, the 2 arrays and their capacity. If the arrays store 9, 0, 3 and 4, 7, 6 the maximum gap is 7 (between the second elements of the two arrays).
Write a C++ program with two user defined functions. The first function named “functionWithArray” takes two user input arguments of character types and return True if first argument is smaller than the second argument (alphabetically) and returns False otherwise. Write the second function named “functionWithPointers” which behaves like the first functions but uses pointers to receive the arguments. You may assume that both character arrays contain only lower-case letters, and no blanks or other non- alphabetic characters. Write a suitable Main function to test these two functions
Write a C program that uses a function to calculate Rt. The user will be prompted to enter R1, R2 & R3 which will be passed to the function as parameters, do not use global variables or pointers. The values have no specified range for them but if any of the 3 inputs are less than 0, the function should return 0. The main function should then display the calculated value of Rt with 2 decimal places or an appropriate error message. (Do not use printf or scanf inside the function ... all input/output should be in main) Use appropriate message to prompt the user to enter each value. Three resistors (R1, R2 and R3) are connected so that R1 & R2 are in parallel then in series with R3. Their equivalent resistance (Rt) is calculated using the following equation: Rt=(R1xR2/R1+R2)+R3
Please send me answer within 10 min!! I will rate you good for sure!! Please provide screenshot of code and output with explaination!! Write a C program that implements and tests a function that simulates strcmp function. You should not use functions from <string.h> library. You may use array and/or pointer notation to define the functions. More precisely, you should implement this function: Hint: int myStrcmp (const char *s1, const char *s2) This function compares the string pointed to by s1 to the string pointed to by s2. If the string pointed to by s1 comes before the string pointed to by s2 in dictionary ordering, then -1 is returned. If the string pointed to by s1 is the same as the string pointed to by s2, then 0 is returned (the compare function is case sensitive). Otherwise, 1 is returned. C program
