Function scale multiples its first argument (a real number) by 10 raised to the power indicated by its second argument (an integer). For example, the function call scale (2.5, 2) Returns the value 250.0 (2.5 x 102). The function call scale (2.5, -2) Return the value 0.025 (2.5 x 10²) Write only the main function, create and initialize a double array and then call the function scale for each elements of the array. At the end, the contents of the array must consist of scaled values. Create and use a separate integer array as the powers of each corresponding value. Eg.

Question

Function scale multiples its first argument (a real number) by 10 raised to the power indicated
by its second argument (an integer). For example, the function call
scale (2.5, 2)
double scale (double x, int n)
double scale_factor;
scale factor - pow (10, n);
return x*scale_factor;
Returns the value 250.0 (2.5 x 102). The function call
scale (2.5, -2)
Return the value 0.025 (2.5 x 10²)
Write only the main function, create and initialize a double array and then call the function
scale for each elements of the array. At the end, the contents of the array must consist of
scaled values. Create and use a separate integer array as the powers of each corresponding
value.
Eg. If double array has the following contents:
1.0 2.0 3.0 4.0 and the
Integer array of powers have the following:
4 3. 2 -2,
After function calls, the new contents of the double array must be updated as in seen in the
following:
1.0x104 2.0x10³ 3.0x10² 4.0x10²

You are given an array of integers and you have to swap the first and last element of the array without using a third variable. Modify the original array and do not create a new array. Time: O(1) Space: O(1) Language: C You need not write the complete code, complete the function, void modify(int *arr, int n){ }
Write the function definition for a value returning function that receives an array of integer values, the array length, and an integer target value as parameters. The function should perform a li ear (sequencial) search for the target value. If the value is found, the function should return the index position of the target value, otherwise, it should return -1. Write only the function definition.

What does it mean to refer to the "base address of an array" when making a function call, and where does that phrase come from?
Problem Statement Average function: Please complete the following function. The function has two parameters which are an integer array and an integer as a size of the array. The function computes the average value by adding all values from each element of an array and dividing them by the size of the array. The function returns an integer of the average value. Example 1 average({1, 2, 3, 4, 5}, 5) → 3 Example 2 average({2, 4, 6, 8, 10, 12, 14, 16, 18}, 9) → 10 Example 3 average({5, 5, 5, 5, 5}, 5) → 5 Partial Solution Please try to implement the full source code in your IDE first. The solution is partially provided below. Fill in the blanks to complete the missing parts and make sure to not add an empty space before and after the answer. } int sum = for(int i = } sum 0; 0; i return sum/ average(int array[], int size) { array size; i++){
5. Write a function which will find the average of all elements of an array of integers. Pass an array and a dimension (the number of elements), and return the value of the average as a float ( the return value). Test this function in the main program with the array: 5, 7, 3, 5, 6, 4.
Complete the code.
When calling a function, what exactly does it imply to say that you need the "base address of an array"?
