Functions

Point out the error in the program


f(int a, int b)
{
    int a;
    a = 20;
    return a;
}

Missing parenthesis in return statement

The function should be defined as int f(int a, int b)

Redeclaration of a

None of above

Answer: Option

Explanation:

f(int a, int b) The variable a is declared in the function argument statement.

int a; Here again we are declaring the variable a. Hence it shows the error "Redeclaration of a"

The default return type of any function is "int", so it is useless to write
"int f(int a, int b)".

Even return type is also missing rite?

We can't re-declare any variable in the same block.
