Help please, what's wrong?
Or give some test cases.

#include <iostream>
using namespace std;

struct figure {
    int type;
    int size;
};

bool (*figureFunction) (int, figure);

bool circle (int holeSize, figure inManhole)
{
    if( inManhole.type == 1 )
        return holeSize >= inManhole.size;
    return 2*holeSize >= inManhole.size;
}

bool triangle (int holeSize, figure inManhole)
{
    if( inManhole.type == 3 ) return holeSize >= inManhole.size ;
    return holeSize > inManhole.size ;
}

bool square(int holeSize, figure inManhole)
{
    switch(inManhole.type)
    {
        case 1: return sqrt(2)*holeSize >= 2*inManhole.size;
        case 2: return holeSize >= inManhole.size;
        case 3: return sqrt(2)*holeSize >= inManhole.size;
        default: break;
    }
}

int testHole( figure hole, figure* manhole, int count)
{
    int willPut = 0;

    switch( hole.type ){
        case 1: figureFunction = &circle; break;
        case 2: figureFunction = &square; break;
        case 3: figureFunction = &triangle; break;
        default: break;
    }

    for( int i = 0; i<count; ++i )
    {
        if(figureFunction( hole.size, manhole[i] )) willPut++;
    }
    return willPut;
}

int main()
{
    figure hole;
    cin>>hole.type>>hole.size;

    int count;
    cin>>count;
    figure* manhole = new figure[count];
    for( int i=0; i<count; ++i )
    {
        cin>>manhole[i].type>>manhole[i].size;
    }

    cout<< testHole( hole, manhole, count);

    delete manhole;

    return 0;
}

Answer: 1

circle:   maxSize := 2 * a;
      minSize := 2 * a;
square:   maxSize := a * sqrt(2);
      minSize := a;
triangle: maxSize := a;
      minSize := a * sqrt(3) / 2;

WA5 - Try to put the circle into the square!!!
