How is comma operator useful in a for loop in C?

The comma operator will always yield the last value in the comma separated list.

What is the advantage of a comma operator?

The comma operator ( , ) evaluates each of its operands (from left to right) and returns the value of the last operand. This lets you create a compound expression in which multiple expressions are evaluated, with the compound expression’s final value being the value of the rightmost of its member expressions.

What does a comma mean in a function?

The comma is used in mathematics to divide long numbers into smaller units, aiding in the identification of place value. In a number that is separated into short segments, the comma is a numeric symbol rather than a mark of punctuation. Consequently, there should be no space before or after the mathematical comma.

What is the difference between C++11 and 14?

C++11 allowed lambda functions to deduce the return type based on the type of the expression given to the return statement. C++14 provides this ability to all functions. It also extends these facilities to lambda functions, allowing return type deduction for functions that are not of the form return expression; .

How do you split in C++?

Different method to achieve the splitting of strings in C++

1. Use strtok() function to split strings.
