Greetings, everyone i have trouble with this exercise in c language

Write a user-defined function

called AddNegative that receives two parameters: an array of integers, and an integer that contains the number of elements in the array. The function adds only the number of values that are negative numbers that appear in the array and returns the total. Example: if array contains 2, -7, - 2,1,5, -6, 6, -5,4, -2 the function would return the number -22 since the negative numbers are -7, -2, -6, -5 and -2 in the array. (Hint: a conditional statement in your loop)
