C.II and III
D.II and IV

Answer 1

II. The body of a function may have many return statements.
III. A function can return only one value to the calling environment.

The above statements are correct.
So the answer is option C. II and III

Answer 2

Answer:

C.II and III

Explanation:

• The body of a function may have many return statements.

• But function can return only one value to the calling environment.

• A return statement ends the execution of a function, and returns control to the calling function.
• Consider the following example:

     main()

      {

      int a=5,fact;

      fact=rec(a);

      printf("Factorial value of %d =",fact);

}

int rec(int x)

{

int f;

if(x==1)

return(1);

else

f=x*rec(x-1);

return (f);

}

• In the above example function rec(x) has 2 return statements in its body but it will return only one value , either 1 or the value of 'f'.
• if x is 1 , the function will execute return(1) and will return 1.
• else, the function will execute return (f) and will return the value of 'f'.
