Question

What is wrong with the following function definition?
test_function (int k)
{
float temp = 5.34
temp = k / 2.0
return temp;
}

Answer 1

If this question asks for function definition then after int k u should give an semicolon(;). Otherwise the statement is not ended by an terminator after temp declaration in first 2 lines inside the functions.

Answer 2

Wrong with the following function definition:

• Although the given function is missing a return type in the function signature, it works fine and without any errors.  

• But it does cause ambiguity in returning the variable temp.

• Although  temp is defined as a float when it divides an integer k say 5 by 2 it is bound  to have two results.

• First is an integer result, which is 2 and second is a floating-point result that is 2.5.

• In the absence of the return type, the function  returns an integer while on the other hand, when the return type is specified as a float,  it returns temp as a float.
