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()); + } + +
