Write two or more of the programs starting at lab61.cpp
Do as many as you can.
Finishing one program perfectly should be your first goal.
Then, try more as you have time.
Each program is given a name indicated.
Do your work in your /2010/6 folder on Odin.
Steps in completing this assignment...
1. Write a program for each of the options below.
2. Each program will use one or more arrays.
3. Functions are optional.
4. Output should look just like the sample given.
In all of your programs, your main function header should look like this:
int main(int argc, char *argv[])
Near the top of the main function, enter this code...
if (argc > 1)
srand(atoi(argv[1]));
else
srand(time(NULL));
Declare an array that will hold 10 integers.
Use a for-loop to fill the array with random numbers from 1 to 80.
Display the array values forward.
Display the array values in reverse order.
Hint: use two different for-loops.
lab6a - 10 random numbers array forward: 43 35 58 66 55 80 4 13 69 46 array reverse: 46 69 13 4 80 55 66 58 35 43 done.
Declare a character array that will hold 100 characters.
Prompt the user to enter their name.
Do a cin into the array.
Display their name downwards. ↓
Hints:
1. Use a while loop.
2. Step through the array elements.
3. Display the character you find, followed by endl.
4. Stop when you find this character: '\0'
(backslash zero inside single-quotes.)
lab6b - your name please enter your name here: Gordon G o r d o n program complete.
Write a program that declares an integer array with size 10.
Fill the array with random numbers from 0 to 20.
Display the array elements in forward and reverse order, side-by-side.
lab61 - forward & reverse 3 18 11 10 2 16 12 4 15 10 10 15 4 12 16 2 10 11 18 3
Write a program that declares an integer array with size 10 or more.
Fill the array with random numbers from 0 to 30.
All array values must be unique.
No duplicate values are allowed in the array.
1. Keep track of how many good values are in the array. There will be zero to start. 2. Use a for-loop to read through the array and test for duplicates. If no duplicates found, add the new value to the array.Sample output:
lab62 - unique numbers only 9 8 3 0 23 15 26 18 6 30
Write a program that declares an integer array with size of at least 20.
Fill the array with random numbers from 0 to 100.
Indicate all duplicate values when displaying the array.
lab63 - show duplicates 17 65 <---duplicate 99 <---duplicate 37 0 36 44 5 25 99 <---duplicate 78 10 69 77 32 20 65 <---duplicate 13 12 31
Write a program that prompts the user to enter a sentence.
Store the sentence in one character array.
Step through the sentence characters using a loop.
Display the words individually.
lab64 - parse a sentence Enter a sentence: Please buy Gordon a new laptop. word 1: Please word 2: buy word 3: Gordon word 4: a word 5: new word 6: laptop.
Hints: Display each character individually. When you find a space, go to a new line. Stop when you find a NULL character in the sentence. A break statement is not allowed. A space character is: ' ' or the value 32. A NULL character is: '\0' or the value 0. To input a whole sentence, you will need to use cin.getline(). We did this in class together. Or, look it up in our textbook.
Write a program that declares an integer array of size 10.
Fill the array elements with 10 random integers between 0 and 100.
Add all the array elements together.
If the total is not 100, fill the array again.
Continue trying until the total is exactly 100.
lab65 - array sums to 100 9 9 12 21 3 24 22 46 5 51 9 60 0 60 0 60 13 73 27 100 number of tries: 670375
Write a program that declares an integer array with size 10.
Fill the array with random numbers from 0 to 20.
Display the array elements like in the sample.
At the bottom, display the 2 smallest values in the array.
lab66 - two smallest 8 12 19 15 17 12 1 14 19 9 1 8 <--- 2 smallest values
Write a function that declares an integer array of size 100.
Fill the array with random numbers from 10 to 20.
Display the array values in ascending sequence.
One space between numbers.
Do not let any number wrap around on an 80-character terminal window.
Note:
Do not use an algorithm you find online.
We will learn to sort in class.
$ ./a.out lab67 - sorted order 10 10 10 10 10 10 10 10 10 10 10 10 11 11 11 11 11 11 11 11 11 11 11 12 12 12 12 12 12 12 12 12 12 12 12 12 13 13 13 13 13 13 13 14 14 14 14 14 14 14 14 14 14 14 14 15 15 15 15 16 16 16 16 16 16 16 16 17 17 17 17 18 18 18 18 18 18 18 18 19 19 19 19 19 19 19 19 19 20 20 20 20 20 20 20 20 20 20 20 20 Sort complete.
