22. Rewrite the following if statement as an equivalent switch statement. The variable digit is of type int.

if (digit == 0)

value = 3;

else if (digit == 1)

value = 3;

else if (digit == 2)

value = 6;

else if (digit == 3)

    value = 9;

23. The decision table below shows fines imposed for speeding violations. Write a code segment that assigns the correct fine to type double variable fine based on the value of type int variable speed.

    Speed (mph) Fine ($)

    65 or less   0

    66-70        15.00

    71-75        30.00

    76-80        75.00

    over 80 100.00

24. Rewrite the switch statement below as a multiple-alternative if statement.

    switch (jersey) {

    case 11:

         printf("I. Thomas\n");

         break;

    case 23:

         printf("M. Jordan\n");

         break;

    case 33:

         printf("S. Pippen\n");

         break;

    default:

         printf("Player unknown\n");

    }

25. What is the output of the following program?

         count = 5;

         while (count > 0) {

           print(“Woot! ”);

           count -= 1;

         }

Answer 1

Program:

#include<stdio.h>
int main() {
int digit=2;// Here initailizing the value of digit to 2
if (digit == 0)
printf("value = 3");
else if (digit == 1)
printf("value = 3");
else if (digit == 2)
printf("value = 6");
else if (digit == 3)
printf("value = 9");
}
Output:

Using Equivalent switch statement

Program:

#include<stdio.h>
int main() {
int digit=2;// Here initailizing the value of digit to 2
switch (digit) {
case 0:
printf("value = 3\n");
break;
case 1:
printf("value = 3\n");
break;
case 2:
printf("value = 6\n");
break;
case 3:
printf("value = 9\n");
break;
default:
printf("NULL\n");
}
}

Output:

Program:

#include<stdio.h>
int main() {
int Speed;
double Fine;// Here initailizing the value of digit to 2
printf("Enter Speed in kmph: ");
scanf("%d",&Speed);
if (Speed <= 65)
printf("Fine = 0");
else if (Speed >=66 &&Speed <= 70)
printf("Fine = 15.00");
else if (Speed >=71 &&Speed <= 75)
printf("Fine = 30.00");
else if (Speed >=76 &&Speed <= 80)
printf("Fine = 75.00");
else if (Speed >80)
printf("Fine = 100.00");
}

Output:

Program:

#include<stdio.h>
int main() {
int jersey=11;// Here initailizing the value of jersey to 11
switch (jersey) {
case 11:
printf("I. Thomas\n");
break;
case 23:
printf("M. Jordan\n");
break;
case 33:
printf("S. Pippen\n");
break;
default:
printf("Player unknown\n");
}
}

Output:

Using multiple-alternative if statement.

Program:

#include<stdio.h>
int main() {
int jersey=11;// Here initailizing the value of jersey to 11
if(jersey == 11)
{
printf("I. Thomas\n");
}
else if (jersey == 23)
{
printf("M. Jordan\n");
}
else if (jersey == 33)
{
printf("S. Pippen\n");
}
else
{
printf("Player unknown\n");
}
}

Output:

  

Program:

#include<stdio.h>
int main() { // Start of main()
int count = 5;// Here initailizing the value of count
while (count > 0) { // Here checking the condition count > 0
printf("Woot! "); // Here this statement is printed if above condition is True
count -= 1; // Here decrementing the value of count by 1
} // En of while() loop
} // End of main()

Output:
