- 3
- 5.74
- 0
- Error
Correct Option: D
The error occurs because we have mixed the ANSI prototype with Kernighan & Ritchie style of function definition.
When we use ANSI prototype for a function and pass a float to the function it is promoted to a double.
When the function accepts this double into a float a type mismatch occurs hence the error. The remedy for this error could be to define the function as:
int fun ( float kk)
{
// code here
}
