C Programming Assignment 3

For each of the programs assigned below, submit a copy of the source code (.c file) saved as an electronic attachment to Assignment 3 located in Canvas under Assignments.

Notes:

Observe the usual guidelines regarding the initial comment section, indenting, and so on.

In if-else statements, indent statements to be executed for if or else conditions three to five spaces. Align else or else if with corresponding if.

Note on problem 1: Be sure to print the three random numbers.

1.Seed the random number generator with time and then generate 3 random numbers between 1 and 500. Write a program to determine and print the largest of the three numbers.

2. Write a program to read in x and y coordinates of a point in the Cartesian plan and then to print a message telling either an axis on which the point lies or the quadrant in which it is found.

In the program, prompt the user to enter the x and y coordinates as floating point numbers. Using selection structures determine the axis or quadrant (I, II, III, or IV based on a counterclockwise numbering) where the point is located. Find a way to do this program that uses if structures other than just simple if.

Print the result as shown in the sample lines of output below:

(-1.0, -2.5) is in quadrant III.

(0.0, 4.8) is on the y-axis.

3. Write a program to calculate a students grade based on three test scores. Prompt the user for three test scores, calculate the average, and then determine the grade using the algorithm below:

If the average score is 90% or more, the grade is A.

If the average score is 70% or more and less than 90%, check the third score. If the third score is more than 90%, the grade is A; otherwise the grade is B.

If the average score is 50% or more and less than 70%, check the average of the second and third scores. If the average of the two is greater than 70%, the grade is C; otherwise the grade is D.

If the average score is less than 50% then the grade is F.

Implement the algorithm using nested statements within a given range rather than merely using all simple if statements. Within the if structure, assign the grade to a character variable. Print the grade at the end of the program.
