C++ - And Logical Operator(&&) - Not Logical Operator(!)

 

And Logical Operator:

• You use the AND operator, && when you have two conditions that must both be true for a true result. 
• The && operator only produces a true result if both operands are true. If either or both operands are false, then the result is false

Examples:

• 6 > 4 && 2 <= 14
• 14 > 7 && 5 <= 5

if(age>25 && income>25000){

 cout<<"Sir,You can apply for Loan"; 

} 

Not Logical Operator:

• The operator accepts a single argument and does the following:
• Converts the operand to boolean type: true/false
• Returns the inverse value.

Examples: 

• !(x > 5)
• if (xyzzy != true) 
• !(x > 3 && x < 10) 
• ! (13 != 7)
