Question

Following is a complete program with a function. What will appear on the screen when you run this program?
#include<iostream>
using namespace std;
int A_function(int a);
int main()
{	int n=10;
	cout<<A_function(n)<<endl;
	n=15;
	cout<<A_function(n)<<endl;
	return 0;
}
int A_function(int a)
{	int c;
	if(a!=10)
	    c=a
	else
	    c=a*2;
	return c;
}

The answer should be 20 and 15 but how come

anonymous · Answer

the value of n mapping in a  when we call  the  function A_function(n).
hence in the definition of the function, when n=10 then a=10 then it will go in else condition.and return 20.
when n=15 then a=15 then it will go in if condition hence it will return 15..
hence output will be 20 and 15..
