What is the value of 1/2 in C?
1/2 will give 0 as output, because they are int by default, compiler will read them as integer type data while compile time. But 1.0/2.0 will give 0.5 as output, as you make them float in this case and compiler will treat them as floating point numbers at compile time.
What does ++ i mean in C?
++i : is pre-increment the other is post-increment. i++ : gets the element and then increments it. ++i : increments i and then returns the element. Example: int i = 0; printf(“i: %d\n”, i); printf(“i++: %d\n”, i++); printf(“++i: %d\n”, ++i); Output: i: 0 i++: 0 ++i: 2.
Is i ++ the same as i i 1?
These two are exactly the same. It’s just two different ways of writing the same thing. i++ is just a shortcut for i += 1 , which itself is a shortcut for i = i + 1 . These all do the same thing, and it’s just a question of how explicit you want to be.
What is modulo in C?
The modulo operator in C will give the remainder that is left over when one number is divided by another. For example, 23 % 4 will result in 3 since 23 is not evenly divisible by 4, and a remainder of 3 is left over.
What is abs () in C?
abs( ) function in C returns the absolute value of an integer. The absolute value of a number is always positive. Only integer values are supported in C. h” header file supports abs( ) function in C language.
What is i1 in C?
1. i– passes i to the function then decrements i value in the caller scope. i-1 passes i-1 to the function and does not change i value in the caller scope.
Which is better i ++ or i i 1?
i=i+1 will have to load the value of i , add one to it, and then store the result back to i . In contrast, ++i may simply increment the value using a single assembly instruction, so in theory it could be more efficient.
What is divide in C?
The ‘/’ – sign is for division. Whenever in C language, you divide an integer with an integer and store the data in an integer, the answer as output is an integer. For example int a = 3, b = 2, c = 0; c = a/b; // That is c = 3/2; printf(“%d”, c); The output received is: 1.
