Question
. Find the output of the following program.main(){ int i = (1, 2, 3); cout << i << endl;}
Solution
The output of the program will be "3".
Here's the step-by-step explanation:
-
The program starts with the main function. This is the entry point of the program.
-
Inside the main function, an integer variable 'i' is declared.
-
The value assigned to 'i' is (1, 2, 3). This is a comma operator, which evaluates its operands from left to right and returns the value of the rightmost operand. So, the value of 'i' becomes 3.
-
The 'cout' statement prints the value of 'i' to the standard output, which is typically the terminal or console. So, "3" is printed.
-
The program ends after executing the main function.
