Functions in C Programming with examples - BeginnersBook.
You know whether a function returns a true or false value by reading the function’s documentation, or you can set a true or false return value when writing your own functions. You cannot compare strings by using an if comparison. Instead, you use specific string comparison functions.
C Program to Make a Simple Calculator Using switch.case In this example, you will learn to create a simple calculator in C programming using the switch statement. To understand this example, you should have the knowledge of the following C programming topics.
As a function can return only one value through its name, we will require two functions in this program to calculate the area and circumference: area and circum. The program given below first defines the main function followed by these functions.
How to write a C Program to find Square root of a Number using sqrt and without using sqrt function with example?. C Program to find Square root of a Number This program allows the user to enter any number and then finds the square root of that number using math function sqrt().
However, not all these equations are functions. In math, a function is an equation with only one output for each input. In the case of a circle, one input can give you two outputs - one on each side of the circle. Thus, the equation for a circle is not a function and you cannot write it in function form.
In the C Programming Language, the log function returns the logarithm of x to the base of e.
Using Math Functions: Write A Program To Demonstrate That The Derivative Of The Sine Function Is The Cosine Function. The Derivative Of A Function Gives You The Slope Of The Function, And Cifyou Haven't Had Calculus Yet, The Slope Of The Sine(x) Is Equal To The Cosine(x). So To Do This, We'll Generate 100 Values Of Sin(x) And Cos(x) For X.
