the problem in concern is CHEFDETE Problem - CodeChef

My program is not compiling and I cant seem to fix it. Could anyone help me understand and correct where and what is wrong syntactically or logically? any hekp ould be appreciated

this is my code in C++
#include<stdio.h>
using namespace std

int main()
{
int a,b,i,j,str[10000],rep[10000];
cin>>a;
for(i=0;i<a;i++)
{
str[i]=i+1;
cin>>rep[i];
}
for(j=0;j<a;j++)
{
for(int k=0;k<a;k++)
{
if str[j]==rep[k]
{str[j]=-1;
 break;
 }
 }
 if str[j]!=-1;
 {cout<<str[j];}
 }
 }
 return 0;
 }

I think this for loop will give you the complilation error. why you are using “=” in cin (I’m not clear)?

for(i=0;i<a;i++) {

=“” str[i]=“i+1;”
cin=“”>>rep[i];
}

You can check this solution. for reference.

Hope this helps!

your header

@srs101 The problem with your code is:

  1. Using wrong header file, use for “cin”

  2. Missing semicolon in 2nd line

  3. Bracket missing in “if” conditions

  4. Poor indentation

    #include
    #include<string.h>
    using namespace std;

    int main()
    {
    int a,b,i,j,str[10000],rep[10000];
    cin>>a;
    for(i=0;i<a;i++)
    {
    str[i]=i+1;
    cin>>rep[i];
    }
    for(j=0;j<a;j++)
    {
    for(int k=0;k<a;k++)
    {
    if (str[j]==rep[k])
    {
    str[j]=-1;
    break;
    }
    }
    if (str[j]!=-1)
    {
    cout<<str[j]<<" ";
    }
    }
    return 0;
    }

I corrected your code. Have a look and compare it with your code and use indentation in your code it will help you in finding bugs easily.

Did you tried to run it in codechef ide and see the error?

Missing semi colon after using namespace std , no brackets for if statement, multiple errors.
