Chapter 3: Problem 11

Write an if-else statement that assigns 0 to the variable b and assigns 1 to the variable c if the variable a is less than 10. Otherwise, it should assign -99 to the variable \(b\) and assign 0 to the variable \(c\).

Short Answer

Expert verified
Question: Write an if-else statement to assign values to b and c based on the value of a such that if a is less than 10, b is 0 and c is 1, and if a is greater than or equal to 10, b is -99 and c is 0.

Step by step solution

01

Set up the if-else structure

Begin by writing an if statement to test whether the variable a is less than 10. If this condition is true, we will assign the desired values to b and c. If it is not true, then we will use an else statement to assign the alternative values to b and c. ``` if (a < 10) { // code to assign values to b and c if a is less than 10 } else { // code to assign values to b and c if a is greater than or equal to 10 } ```
02

Assign the values for b and c if a is less than 10

If the condition "a < 10" is true, we want to assign 0 to b and 1 to c. To do this, add the following code to the first block of the if statement: ``` b = 0; c = 1; ``` The updated if-else statement should look like this: ``` if (a < 10) { b = 0; c = 1; } else { // code to assign values to b and c if a is greater than or equal to 10 } ```
03

Assign the values for b and c if a is not less than 10

If the condition "a < 10" is not true (meaning a is greater than or equal to 10), we want to assign -99 to b and 0 to c. To do this, add the following code to the else block: ``` b = -99; c = 0; ``` The completed if-else statement should look like this: ``` if (a < 10) { b = 0; c = 1; } else { b = -99; c = 0; } ``` This if-else statement will now correctly assign values to b and c based on the value of a.
