In this blog, you will learn about functions in C programming, including their definition, types, and how to use them to make your code more modular and efficient.
The example below showcases the implementation of an inline function in C++. Code Example: #include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() {...
When we declare a function in C, it must match the type of the function definition. For example, if we define a function to return an integer, the declaration must also define the function to return an integer. If the types of the definition and the declaration do not match, the“confli...

Now that the definition of cosine has been given and its graph has been presented, consider a few examples of how to use cosine. Try to solve the problems prior to looking at the solutions. Example 1 Use Figure 4 to find the cosine of the angle x. Figure 4. Right triangle ABC with...
Applied to a function declaration, the extern keyword in fact does nothing: the declaration extern int incr(int) is exactly the same as int incr(int). This is because all function declarations have an implicit extern applied! This also applies to function definitions: the function definition ...
You will often see C programs that have function declaration above main(), and function definition below main().This will make the code better organized and easier to read:Example // Function declarationvoid myFunction();// The main methodint main() { myFunction(); // call the function ...
Now we, need to create a function call for the getstring function and pass the string variable in it. Let us commence coding for our getstring function. We have passed the string argument from the main function. Create a function definition and display the string parameter for assurance. ...
