Elementary level of C language – function

1. Concept of function When we mention functions, we immediately think of learning functions in mathematics, such as: y=kx + b. But functions in C language are different from those in mathematics. Wikipedia defines C language functions like this: function, also known as subroutine. A portion of code in a large program, consisting of one […]
