C programming

3 Tests: Write a program to read 10 integer numbers from file "data.txt" into an array of size 10, calculate the summation and find out the largest value. 1)The program should include three more functions, readFile(int int), largest(int int), summation(int int) 2)These three functions should be called in the main function. 3)readFile is implemented to read data from data.txt into the array, D. 4)Summation is implemented to calculate the summation value from the array, 5)Largest is implemented to find out the largest Value from the array (20.09)
