The VOID keyword.

The void keyword allows us to create functions that either do not require any parameters or do not return a value.

The following example shows a function that does not return a value.

void Print_Square(int Number); main() { Print_Square(10); exit(0); } void Print_Square(int Number) { printf("%d squared is %d\n",Number, Number*Number); }

The next example shows a function that does not require any parameters:

#include #include int Random(void); main() { printf("A random number is %d\n", Random()); exit(0); } int Random(void) { srand((unsigned int)time((time_t *)NULL)); return( rand()); }
