Example Inside main, call myFunction(): // Create a functionvoid myFunction() { printf("I just got executed!");}int main() { myFunction(); // call the function return 0;}// Outputs "I just got executed!" Try it Yourself » A function can be called multiple times:...
In the above snippet we have defined the function signature using 2 integer parametersa&band an out parametermax. The function returns the minimum value between a & B and also assigns the maximum value to the output parameter. If the functionMultipleReturns()does not set any value to max va...

Add a Sine Wave block of amplitude 1 to the input of the C-MEX S-function block and a Scope block to the output. Run the simulation. The C-MEX S-Function block returns the value of its floating-point input multiplied by two. It behaves like the C function double...
However, for built-in C types, a function can return only a single object of the type specified in the function signature. It is not possible to define a function with multiple return types. You cannot, for example, have a function that returns three differentintobjects. If you want to ...
putchar() – This C standard library function outputs a single character to the standard output stream, often the console, and then returns the character as an integer value. To write a single character to the screen or a file, use the putchar function. It just needs one argument, which...
