Consider the following program written in C syntax:
Question 4: Consider the following program written in C syntax:
void swap(int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
}
void main() {
int value = 4, list[5] = {1, 3, 5, 7, 9};
swap(value, list[0]);
swap(list[0], list[1]);
swap(value, list[value]);
}
For each of the following parameter-passing methods, what are all of the values of the variables value and list after each of the three calls to swap?
1. Passed by value
2. Passed by reference
3. Passed by result
By value | By reference | By result | |
Output | |||

Given the following program in a C-like syntax, what does F1(m) return assuming static scoping and dynamic scoping? You can assume that expressions are evaluated from left to right. int m = 3; int F1(int i) { return (i + F2(m) + m); } int F2(int j) { j++; return (j * m); } int main() { int m = 5; F1(m); } Explain in details how you got the answers to earn full credit.

I'm trying to code a C program so it sorts an array of integer numbers of size n in ascending order. My code is written below but its not working properly, its giving me errors, I think my sort and swap functions aren't done right maybe, please help and fix. It says "undefined reference to "SelectionSort" as an error. But the question asks to not change the PrintArray and Main function. #include <stdio.h> void PrintArray(int size, int array[]) { for...

I do not understand why the swap methods are not doing anything
for the variable x and y in the main method. When are variables
affected by the other methods and when they do not get modified by
the other methods? (The answer is A).
