Write a statement that declares a prototype for a function t

Write a statement that declares a prototype for a function twice, which has an int parameter and returns an int.

Solution

Please follow the data and description :

A statement that declares a prototype for a function twice which has an int parameter and returns an int is given by,

int twice(int);

Here, the int defines the return type for the function with the name twice and the parameter here is the integre datatype.

Hope this is helpful.
