I am writing code of ACM problem in which we have to check possibilities of different items. It's some minor error in the code.
#include<iostream>
using namespace std;
void CheckPossibilities( int numItems, int maxWeights )
{
if( numItems <= 0 )
{
cout << "Invalid Items";
}
if ( maxWeights <= 0 )
{
cout << "Impossible";
}
while( maxWeights > 0 )
{
if(numItems%2==0) //for even
{
numItems = numItems / 2;
maxWeights--;
}
else
{
numItems = (numItems -1)/ 2; //for odd
maxWeights--;
}
}
if( numItems <= 1 )
{
cout << "Possible";
}
else
{
cout << "Impossible";
}
}
void main()
{
int numItems1,maxWeights1;
cout<<"enter numItems"<<endl;
cin>>numItems1;
cout<<"maxWeights"<<endl;
cin>>maxWeights1;
cout<<numItems1 "AND" maxWeights1<<endl;
cout<<CheckPossibilities(numItems1, maxWeights1);
}

Answer 1

Your mistakes were trying to cout multiple strings in one line without concatting them in some way, either seperate with a << or a +. You also cant cout a void function because it tries to output void, you just need to call it and let the function do the outputting. With errors fixed the main should be
int main()
{
int numItems1,maxWeights1;
cout<<"enter numItems"<<endl;
cin>>numItems1;
cout<<"maxWeights"<<endl;
cin>>maxWeights1;
cout<<numItems1+"AND"+maxWeights1<<endl;
CheckPossibilities(numItems1, maxWeights1);
return 0;
}
Next time look at what line the error is thrown on when compiling and search those specific error because these were really simple and specific syntax errors that could be found by a google search easily.

Answer 2

void main()
{
int numItems1, maxWeights1;
cout << "enter numItems" << endl;
cin >> numItems1;
cout << "maxWeights" << endl;
cin >> maxWeights1;
cout << numItems1 << "AND" << maxWeights1 << endl;
CheckPossibilities(numItems1, maxWeights1);
}
you can never do this: cout<<CheckPossibilities(numItems1, maxWeights1); cout take standard output stream, not functions. And also you forgot to put << in cout << numItems1 << "AND" << maxWeights1 << endl; in this form, your code build succesful.
