simple c++ program

[idsuni]

So i started programming a few days ago and wanted to do a little C++ program. Can anyone explain me why it prints 0 instead of 1? What do I need to change? Best regards.

#include <iostream>

using namespace std;

int main ()
{
    int i;
    i = 0;

    if (int i = 0)
    {
        i++;
    }
    else 
    {

    }

    cout << i << endl;

    return 0;
    
}

You've redeclared your i variable inside your if statement. The i++ is incrementing that i rather than the i that's being outputted.

@Funce, It seems that you never got a thank you for your reply.

So, in the spirit of all that is good let me do it, as you are unlikely to get it from the OP.

 

THANK YOU VERY MUCH

You will declare  <iostream.h> instead of <iostream> in your file . You have declared int i twice. but actually all languages are one time declare to variable. You can add only i=0 in if statement. if you have not another variable so i++ not working

#include<iostream.h>

using namespace std;

int main ()

{

int i,n=5;

for (i=0;i<n;i++)

{

cout<< i << endl;

}

return 0;

}
