4. Write a program that finds the smallest element in a one-dimensional array containing 20 integer values in the range 0 to N Hint: Consider following fragment of code for (c = 1; c < size; c++) { } if (array[c] < minimum) { } minimum = array [c]; location = c+1;

Pure function use provides several benefits.

Write a C++ program with a function named num_type() that takes one parameter of type float and return -1 if the parameter is negative, 0 if the parameter is zero, and 1 if the parameter is positive. Write a main() function that inputs 50 float numbers and finds the sum of positive numbers (use the function num_type).

Write a Haskell function that takes the circumference of a square as inputand computes the area of the square. Within your function you should first compute an intermediate result.
