Problem: Article: This common library allows you to change the color that the text output displays. Add the following code to the top of your program: #include<stdio.h> This will make it easier to capture keyboard input from the user. Add the library below the stdio.h library: #include<stdio.h> #include<conio.h> You can use this function to vary the text colors of your output. Colors must be written in all caps, or expressed as a numeral: #include<stdio.h> #include<conio.h> main() { textcolor(RED); // You could type "4" instead of "RED", but it is not as readable } Color Numerical Value BLACK 0 BLUE 1 GREEN 2 CYAN 3 RED 4 MAGENTA 5 BROWN 6 LIGHTGRAY 7 DARKGRAY 8 LIGHTBLUE 9 LIGHTGREEN 10 LIGHTCYAN 11 LIGHTRED 12 LIGHTMAGENTA 13 YELLOW 14 WHITE 15 There are more colors than this. The colors available depend on the installed graphics drivers and current mode. Colors must be written in all caps. Include a cprintf function to display some text in your new color. Use a getch function at the end to close the program when the user presses a key. #include<stdio.h> #include<conio.h> main() { textcolor(RED); // You could type "4" instead of "RED", but it is not as readable cprintf("Hello, World!"); getch(); return 0; }
Summary: Include the Standard Input and Output library. Include the Console Input and Output library. Use the textcolor function to define what color you want to use for text. Add output text and finish the program.

INPUT ARTICLE: Article: Sweet potato slips need a bit more space than some other garden vegetables, so dig your holes 1224 inches (30.561.0cm) apart each. They need be only as deep as the root ball on the bottom of the slips and about an inch up the base of the plant. Place each small slip in your pre-dug holes and cover the stems with soil about of an inch up the base. The leafy part of the potato plant will begin to sprawl in vines outwards while the roots will produce the tubers between 612 inches (15.230.5cm) deep in the soil. Protect your sweet potatoes from cold weather by adding your chosen mulch to the top. This will also help to block out weeds and prevent too much vine growth, which steal energy from tuber growth. At first planting the sweet potatoes will require a lot of water. Over time, you should reduce the amount that you water them until they receive moisture only about once a week. Begin watering daily, knocking off days from your watering schedule as each week progresses. Sweet potatoes have a relatively long fruiting period, becoming ripe and ready to harvest in the early fall (hence their association with Thanksgiving). Continue watering on a weekly basis, and weeding the beds if necessary to keep the plants healthy. After about 120 days after planting, the sweet potatoes should have reached full maturity. When possible, wait until the last possible time (the last warm weather before a frost) to harvest the sweet potatoes, as this will result in larger and more tasteful tubers. One of the most important steps, sweet potatoes must be cured after harvest. This will help them to develop their flavor (they won't have much immediately after being dug up) and to grow a tougher skin - literally. Place the sweet potatoes in an area with a temperature of 8595F (2935C) with 80-90% humidity for 5-10 days. After this, they should be ready to eat! Consider using a small space heater and a humidifier in a large closet or small room to cure the potatoes. One of the best things about these lovely tubers is that they will remain fresh and good to eat for many months if stored properly. Keep the potatoes in temperatures hovering around 70 degrees (that means no refrigeration!) in an open, dry area. Never store your sweet potatoes in a plastic bag or tightly sealed container.

SUMMARY: Dig your holes. Plant your potatoes. Add your mulch. Water the plants. Wait for the tubers to develop. Harvest the sweet potatoes. Cure the sweet potatoes. Store your sweet potatoes.

In one sentence, describe what the following article is about: To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos(x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline. Example: Find the normal force of a block with a mass of 4.2 kg, sitting on a ramp with an incline of 45 degrees. The cosign of an angle equals the sine of the complementary angle, or the adjacent side divided by the hypotenuse of the triangle formed by the incline. This value is often determined by a calculator, since the cosine of any angle is constant to that angle, but you can compute it manually, as well. Example: cos (45) = 0.71 The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Note that the gravitational acceleration at the Earth's surface is a constant: g = 9.8 m/s2 Example: weight = m * g = 4.2 * 9.8 = 41.16 In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline. Example: N = m * g * cos(x) = 41.16 * 0.71 = 29.1 The previous step should complete the problem and give you your answer. Note that for an object sitting on an incline, the normal force should be less than the weight of the object. Example: The normal force is 29.1 N.
Summary:
Use the right equation. Find the cosine of the angle. Find the object's weight. Multiply the two values together. Write your answer.
