Please tell the meaning of error and how to resolve it as i cant find anything online....

Question

#include <iostream>
using namespace std;

class system
{
float amount;
public:
system(float a): amount(a)
{
}

if (amount >= 1000)
{
amount = amount-(amount*0.1);
}
cout << "The net amount to be paid is:" << amount;

};

The error is "excepted member name or ';' after declaration specifiers."

Answer 1

Rashim Narayan Tiku You are trying to execute statements that don't belong to any particular method in the declaration of a class, which is illegal C++.To put it simple, it's just the syntax of C++ not allowing you to do so.

Sorry I omitted the details in the previous post. Your full code should include both the if and cout statements in the constructor body.

Answer 2

The braces after the constructor are in the wrong place. The if statement should be in the constructor body, not after.

Expected:
system (float a) : amount (a) {
if (...)
}

Error:
system (float a) : amount (a) {}
if (...)

Hoàng Nguyễn Văn Thanks
but why is this way wrong ?

P.S. the cout after the if(...) also needs to be inside the constructor to remove the error...

Rashim Narayan Tiku Classes are data types, like structures, not subprograms, like functions, even though they contain code.
