Q10) implement the following C++ program which includes the following members: 1) Implement the function readFile as follows: a. The function accepts one parameter of type vector. The vector will store double data types. b. The function reads the content of the file InputData. txt and add them to the vector parameter. c. The function returns true if all values were successfully added to the vector. Otherwise, return false. 2) Implement the function position0f as follows: a. The function accepts two parameters, a constant vector parameter and a parameter of type double (called searchFor). b. The function returns the position of searchFor in the vector. If the value is not found, return -1. For example, if the value of searchFor is at the beginning of the vector, the function returns 0. If it is in the second position, the functions returns 1 ... 3) Write a main function as follows Invoke the function readFile. If the function returns true, continue to the next step, otherwise print an error message and terminate the program. b. Invoke the function position0f. Use the vector from the previous step and search for the value 37.89. Print the retuned result. Hint: this function call should returns 16. c. Invoke the function position0f once more and search for the value 10.01. Print the retuned result. Hint: this function call should returns -1. d. Copy the data from the vector into an array of size 30. If the value in the vector is negative, change it positive then add it to the array. The final version of the array should only contain positive numbers. а.
