Write a C++ function, smallestIndex, that takes as parameters an int array and its size and returns the index of the first occurrence of the smallest element in the array. Also, write a program to test your function.

Write a program to compute some election results. A. Define a struct called Candidate that is able to record the name (string) and number of votes a candidates receives. B. Write a function sumVotes that accepts two arguments: an array of Candidate and the size of the array. The function should return the total number of votes received by all the candidates. This function should not do any output. C. Your main function should declare an array of ContactInfo structs of size 4, input the data into the array, and call the function to compute the total votes cast, and output this value. It should then output a table of the names of each candidate and the percentage of votes they received. The percentage can be computed by multiplying the candidates votes time 100.0 divided by the total votes. Ex: If the input is: Miller 5000 Guzman 4000 Harris 6000 Kimmel 1800 Then the output is Total 16800 Miller 29.76 Guzman 23.81 Harris 35.71 Kimmel 10.71 Do not use any prompts to get the input values.…

Can you help me write a C++ program to do the following: Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1, 2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver

Write a function that accepts (but does not read) a 2D array of marks and length (the number of students).  The function returns a one-dimensional array with the total marks of the students and the class average. Write the declarations, and show the call to the function from function main.  Assume all input and output take place in function main, not in this function, and you do not have to write the code to read in the data.  Show the main program and the function call.   const int NUM_STUDENTS = 35; const int NUM_ASG = 5; //Purpose: To calculate the total marks for 35 students and the class average //PreCondition: marks is a 2D array already filled with 5 marks for each student //                             length is the actual number of students with marks //Post Condition: total is a 1D array which is the total of the 5 marks for each student avg is the class average of the total array (for length number of students) void TotalAverage(const double marks[][NUM_ASG], int length,…
