PASS Week 5: Conditions, If-Else, and Logic

PROBLEM #1: If-Else Statements

Create a program that will prompt the user to enter in two integer
values; Store them in the variables nbr1 and nbr2 (These steps have been done for you).
Use an if/else construct to print out the following conditions if they
are true “nbr1 <= nbr2” or “nbr1 > nbr2”.

SAMPLE OUTPUT:
Please enter two integers: 4 5
4 <= 5

MORE SAMPLE OUTPUT:
Please enter two integers: 7 7
7 <= 7



/****** SKELETON CODE ******/

#include <stdio.h>

int main (void)
{
	// Local Declarations
	int nbr1;
	int nbr2;

	// Statements
	printf("Please enter two integers: ");
	scanf ("%d%d", &nbr1, &nbr2);

	//YOUR CODE HERE

	return 0;
} // end main
















PROBLEM #2: Nesting If-Else Statements

In this problem, you will go deeper with your If-Else statements by nesting (inserting) ANOTHER If-Else
statement inside of an already existing one.
Modify the program from PROBLEM #1. INSIDE the block that checks nbr1 <= nbr2, insert
another if-else block.
Then, use the new if-else block to determine which case is true: "nbr1 < nbr2" or "nbr1 == nbr2"
And print the appropriate message to the user for each condition.

SAMPLE OUTPUT:
Please enter two integers: 5 6
5 < 6

MORE SAMPLE OUTPUT:
Please enter two integers: 7 7
7 == 7

PROBLEM #3: Calculating a student's Grade

In this program you will be calculating a student's Letter Grade
for an assignment. The variables for the score and the letter grade
have been made for you, as well as the printf and scanf for input.

Using the skeleton code below, ADD a switch statement in the
program that takes the score variable and prints the char variable that
corresponds to the letter grade earned. 90 to 100 is an ‘A’, 80 to 89
is a ‘B’, etc.
HINT: You can narrow the number of cases by changing the value from a 93 to a 9 or a 26 to a 2 by using integer division.

/****** SKELETON CODE ******/

#include <stdio.h>

int main (void)
{
	// Local Declarations
	double score = 0.0;
	char grade;

	// Local Statements
	printf("Enter the test score (0-100): ");
	scanf ("%lf", &score);


	//YOUR SWITCH STATEMENT HERE


	printf("The grade is: %c\n", grade);

	return 0;
} // main














PROBLEM #4: Creating and Using Flags

Often a program will need to change its execution based on some user condition or exception,
like if the user requests to QUIT the program or there is an ERROR detected.
As a programmer, here is what you can do to help with this: Flags.
A flag variable can be set to a condition and a switch statement can be a handy way to determine
what to do given that condition.

Write a program that prompts the user to enter in an integer value 1 thru 3.
In the case that the value is 1 or 2, print “An error occurred.\n”.
In the case that the value is 3 print out “google i lost superbowl bet and am 8 million in debt what do i do.\n”.
USE SWITCH-CASE TO CHECK. NOT IF-ELSE.
After checking the cases, regardless of value of the flag, print out a message to the user
letting them know the program is terminating with the message
“Good luck bro, goodbye.\n”.



















PROBLEM #5: Find the median value of three values

Using nested if/else conditions, write a program that will prompt for then take three
unordered integer values as input. Your if/else construct should determine which value is
the median valueof the three. If you use a comparison operator ‘==’ make sure not to
confuse it with the ‘=’ assignment operator. It might make it easier to draw the various
conditions using pencil and paper. This is an example of where a flowchart design tool could
help verify your logic.



/****** SKELETON CODE ******/

#include <stdio.h>

int main(void)
{
	int a, b, c, median;
	printf("Enter in 3 integer values.\n");
	scanf("%d", &a);
	scanf("%d", &b);
	scanf("%d", &c);

	//Your code here


	return 0;
}
