Question

Write an if/else statement that compares the double variable pH with 7.0 and makes the following assignments to the bool variables neutral, base, and acid: false, false, true if pH is less than 7 false, true, false if pH is greater than 7 true, false, false if pH is equal to 7

Answer 1

Answer:

Following are the if/else statement

if(pH < 7) // if ph is less then 7

{

neutral = 0;  // false

base = 0;  // false

acid = 1; // true

}

else if(pH > 7) // if ph is greater then 7

{

neutral = 0;  // false

base = 1;  // true

acid = 0; // false

}

else  // if ph equal to 7

{

neutral = 1;  // true

base = 0; // false

acid = 0;  // false

}

Explanation:

Following are the description of statement

• In this  neutral, base, and acid are the boolean variable .We have to check the three condition .
• If ph is less then 7 then we have to initialized the  neutral = 0,base = 0 and
• acid = 1  with the boolean value.
• If ph is greater then 7 then we have to initialized the  neutral = 0,base = 1 and acid = 0  with the boolean value.
• If ph is equal to 7 then we have to initialized the  neutral = 1,base = 0 and
• acid = 0 with the boolean value.
