How do you write or operator in C++?
The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1. The ^ (bitwise XOR) in C or C++ takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different.
How can I compare two strings in C++?

Returns one of two parts, depending on the evaluation of an expression. You can use IIf anywhere you can use expressions. You use IIf to determine if another expression is true or false. If the expression is true, IIf returns one value; if it is false, IIf returns another.
What is the IIF equivalent in C?
This tutorial will demonstrate how to use the IIF Equivalent in C# and other alternatives. IIF stands for immediate if and is available in the Visual Basic programming language. In a single line, you can pass a particular condition and specify the values to be returned if the condition is found to be true or false.
