Hey Mate here is your answer

Advantages of function prototype: - It helps the compiler in determining whether a function is called correctly or not. Each time when a function is called, its calling statement is compared with its prototype. In case of any mismatch, compiler reports an error. Float amount ( int p, int n, float r)

Answer 2

$<b>$ Advantages of function prototyping:-

=> Enables a compiler to carefully compare each use of the function with the prototype to determine whether  the function is invoked properly i.e., the number and type of arguments are compared and any wrong number  or type of the arguments is reported.

=> Tells the program about the return type .

=> Tells the program the number and type of arguments.
