Answer:
In C++, if a function does not specify a return type, the default return type is int. If a function does not return a value, the default return value is undefined.For example, the following function has a default return type of int:
// Default return type is int
void foo()
{
// Do something
}
If you want the function to return a value, you can specify the return type and use the return statement to specify the value to be returned. For example:
int add(int x, int y)
{
return x + y;
}
This function has a return type of int and returns the sum of its two arguments.It's generally a good practice to explicitly specify the return type of a function, even if it's int, to make it clear to the reader what the function is expected to return.
