PASS Week 3/3

PROBLEM #1

Create a program using the skeleton below that will prompt the user to enter in two integer
values: nbr1 and nbr2. Use an if/else construct to print out if nbr1 <= nbr2 or else if nbr1 > nbr2.

In your if/else statements, print out the statements verbatim like this:
    printf("nbr1 <= nbr2\n");


/*** 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

Modify the program from Problem 1 to use NESTED if/else blocks of code to determine in
the case if nbr1 <= nbr2, the case is also true if nbr1 < nbr2 or else nbr1 == nbr2















PROBLEM #3

In this problem, we will be calculating a students letter grade by using the percentage.
Treat the percentage as an integer between 0-100.
Using the skeleton code below complete a SWITCH statement in the
function that takes the score value and returns the char value that
corresponds to the letter grade earned. 90 to 100 is an ‘A’, 80 to 89
is a ‘B’ etc. Most of the code is given to you. You just have to
write the switch statement itself.

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. What
if the user supplies a floating point?

/*** SKELETON CODE ***/

#include <stdio.h>

// Function Declarations
char scoreToGrade (float score);

int main (void)
{
    // Local Declarations
    float score;
    char grade;

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

    grade = scoreToGrade (score);

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

    return 0;
} // end main


/* ==================== scoreToGrade ===================
This function calculates the letter grade for a score.
 Pre the parameter score
 Post returns the grade
*/
char scoreToGrade (float score)
{
    // Local Declarations
    char grade;
    int temp;

    // Statements
    temp = (int)(score / 10); //Without the cast it would still be narrowed to an integer

    //YOUR SWITCH STATEMENT HERE

    return grade;
}//end function ScoreToGrade















PROBLEM #4

Using the random number generator compose a program that seeds the
random number generator using system time. Use the random number
function to returns a value within a range of 1 - 3. Use a switch
statement to determine the following. If the number returned is 1 print
out “The computer chose Rock.”, if it’s 2 print out “The computer chose
Paper.”, if it’s 3 print out “The computer chose Scissors.”

Set the range: range = (max value - min value) + 1;



/*** SKELETON CODE ***/

#include<stdio.h>
#include<time.h>

#define MAX 3
#define MIN 1

int main(void)
{


    int range = ;
    int compChoice = ;

    switch(compChoice)
    {

    }

    printf("Good bye!\n");
    return 0;
}//end main












BONUS PROBLEM

Using nested if/else conditions, write a program that will prompt for then take three integer
values as input. Your if/else construct should determine which value is the median value of
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 a simple 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;
}
