Assignment

This is a simple repository you will use to finish the assignments contained in this README.md document.

Instruction

You are to create separate files for each question and upload those to your repositories. After which you will create a pull request when you are done with your assignment. For more information on how to use GitHub, check out this link on [GitHub Flow](https://guides.github.com/introduction/flow/,"GitHub Flow").

In essence, you will fork this repository to create your own master copy of it. Do the assignment and create a pull request with your different files. which I will observe and score.

Question One

Fix the Bug in the following code so that it runs correctly

                    /* a program with problems... */
                    #include <stdio.h>
                    int x= 1:
                    main()
                    {
                        if( x = 1);
                            printf(" x equals 1" );
                        otherwise
                            printf(" x does not equal 1");
                        return 0;
                    }

My take

                    /* a program with problems... */
                    #include <stdio.h>
                    int x= 1; // this is supposed to be semi colon not full colon
                    main()
                    {
                        if( x = 1)// remove semicolon
                            printf(" x equals 1" );
                        else
                            printf(" x does not equal 1");
                        return 0;
                    }

Question Two

Write a header for a function named do_it() that takes three type char arguments and returns a type float to the calling program.

Write a header for a function named print_a_number() that takes a single type int argument and doesn't return anything to the calling program.

What's wrong with the following program ?

                    #include <stdio.h>
                    void print_msg( void );
                    main(){
                        print_msg("This is a message to print");
                        return 0;
                    }
                    void print_msq( void )
                    {
                        puts("This is a message to print");
                        return 0;
                    }

My take

//TODO 1: Header functions have a .h file extension so you need to create that
// Declarign function as Float is key in this question

float do_it(char arg1, char arg2, char arg3);
float do_it(char arg1, char arg2, char arg3){
    //does something
}
//TODO 2: Keyword to look for is "does not return anything"

void print_a_number(int arg1);

//TODO 3: What's wrong? Does not take parameters from definition
print_msg("This is a message to print");// this not right

Question Three

Write a declaration for an array that will hold 50 type long values

Show a statement that assigns the value of 123.456 to the 50th element in the array from the above question

What is the values of x when the following statement in complete ?

    for (x = 0; x < 100; x++)

What is the value of ctr when the following statement is compelte ?

   for(ctr = 2; ctr < 10; ctr += 3)

Write a while statement to count from 1 to 100 by 3s

What is wrong with the following code fragment (MAXVALUES is not the problem !)

    for (counter = 1; counter < MAXVALUES; counter++ );
    printf("\nCounter = %d", counter);

My take

//TODO 1: Declaration for an array that will hold 50 type long values
    double long array[50];

    //TODO 2: Statement that assigns 123.456 to 50th element
    array[49] = 123.456;

    //TODO 3: value of x from for loop. In this question 99 and 100 are correct because it was not explicit which x to consisder
    for (int x = 0; x < 100; ++x) {
        //x == 99
    }
    //Outside loop x == 100 is correct

    //TODO 4: similar thinking applies to
    for (int ctr = 2; ctr < 10; ctr+=3) {
        //ctr == 8
    }
    //ctr == 11;

    //TODO 5: Wha is wrong; indentation without the {} is important it should be
    for (int counter = 0; counter < MAXVALUES; ++counter)
        printf("\nCounter = %d", counter);

Question Four

Write a function named addarrays() that accepts two arrays that are the same size. The function should add each element in the arrays together and place the values in a third array.

Modify the function you created to return a pointer to the array containing the totals. Place this function in a program that also displays the values in all three arrays.

My Take

#define SIZE 10

//TODO 1: Declare a function called add_arrays(arg1, arg2) that takes arguments of array data type
void add_array(int arr1[SIZE], int arr2[SIZE]);
main() {
    int arr1[SIZE] = {1,2,3,4,5};
    int arr2[SIZE] = {1,2,3,4,5};

    add_array(arr1, arr2);
}
//TODO 2: Define how the function will operate
void add_array(int arr1[SIZE], int arr2[SIZE]){
    //TODO 3: Declare two pointers which will access the arrays' addresses
    int *ptr1, *ptr2, sum[10];
    ptr1 = arr1; ptr2 = arr2;

    // Because our pointers now have the addresses of the arrays, we can increment the addresses and add each
    // value element of each array

    for(int i = 0; i < SIZE; i ++){
        sum[i] = *ptr1 + *ptr2;
        ptr1++; ptr2 ++;

        printf("%d, ", sum[i]);
    }
}
