These are the (low-level) types of instructions that the computer (processor) understands. They are not human readable; they are machine dependent - only worked on the machine that it was developed for (not portable).

(a)  

After compiling a program but before it can be executed, this is the step that links or adds to the object code any other code being included with the program (from the #includes or from the other program files that are all being compiled together) which then produces the executable program

(a)  

These are logical errors, e.g. using a variable that hasn’t been declared yet.

(a)  

This refers to the approach or steps taken to solve the problem, to show the logic for the program before you start coding.

(a)  

These are language-specific omissions/errors, e.g., missing a semi-colon where one is required.

(a)  

The second sub-step when compiling where the programming language instructions are broken down into assembly language instructions first (.s file) and then converts each assembly language instruction into binary code, or object code (.o file).

(a)  

These are also low-level types of instructions that, starting in the early 1950s, allowed the programmer to use a somewhat more English-like way of writing instructions by using abbreviations, or mnemonic codes, to refer to the bit-patterns.

/* why won’t this program compile? */

#include <stdio.h>

int main(void) {

int inputNumber;

int a = 10, b = 20;

float c = 4.2, d = 3.0

printf(“Enter an integer \n”);

scanf(“%d”, inputNumber);

printf(“The sum of a and b is \n”, sum);

printf(“a multiplied by your number is %i\n”, a * inputNumber);

printf(“c added to d is %i\n”, c + d);

return 0;

}

What should the format string be instead

int a = 100, b = 2, c = 25, d = 3, e = 1;

int result;

result = e + c % d

printf (“%d”, result);

result = -a + d;

int x = 3, y = 9;

int result;

result = x + 5 * y / 3 * x;

printf (“%d”, result);

int result;

result = x + ((5 * y) / (3 * x));

printf (“%d”, result)
