We use PHP if statement with && (AND) operator to check the two conditions. If both the conditions are true AND (&&) operator return true otherwise return false. In PHP, we have an "and" keyword similar to the "&&" (AND) operator, but it has lower precedence than using an && (AND) operator. Therefore, it is best to avoid the "and" keyword for better clarity, and it also sometimes behaves differently in complex expressions. Basic Syntax if (condition1 && condition2) { echo "Both conditions are true!"; } 1) A block of code executes only if ... Read More

Problem Description In this problem, we are given two numbers, and we have to find the value obtained after adding one number to another.
