Question

The If statement

Admission to the pool is free for children under 7 years of age.
The given program takes age as an input.

Task
Complete the code to output "free" if the child's age is less than 7.

Sample Input
6

Sample Output
free
Don't print anything if the age is above or equal to 7.

I tried this way only 2 cases were right:

#include <iostream>
using namespace std;

int main() {
int age;
cin >> age;
if (age<7);
cout<<"free";

// your code goes here

return 0;

Answer 1

You need to remove the semicolon after the if condition.

if (age <7)
...

Answer 2

Generally, semicolon is used to end a statement. If you put this after if statement, if and cout are separated as two statements.
So, you always get "free" as output since it doesn't depend on if statement.

Answer 3

@Simba thanks dude it worked but I don't understand why remove semicolon the if statement supposed to end with semicolon isn't it?

Answer 4

@Simba I did exact but case 3 was wrong: When input 8 it still prints free and supposed to print nothing
