Output
In the above program, a variable ‘a’ is initialized with a value. The value of variable is printed and assert() function is called. https://recordenergy282.weebly.com/button-boot-camp-mac.html. As assert() is called, it evaluates the expression that ‘a’ is not equal to 15 which is false that is why it aborts the execution and shows an error.
