Question

Explain If…else statements

Answer 1

Answer is in the attachment

Answer 2

If and else statements are used to execute code blocks if the specified condition is true.

• They are called conditional statements as they are used to perform different  tasks on the basis of the conditions.

• Use if to execute the code block, if a specified condition is true, otherwise else can be used additionally to evaluate a different outcome if the the statement is wrong.

• Else if can be used when we want to try out a different set of code statements for a different variant of outcome upon the execution of that code block.

for example:

int a=5;

int b=2;

int c=10;

if (a<b)          

{ a=a+b;

}

 else if ( a<c)

 {a=a+c;

 }

 else

 {

 cout<<"a is the largest";

 }

Here, the code will reach the else statement block only if the above ones are incorrect.
