Check severeal boolean returns in same time?

Question

I have several bool elements and I am checking it if returns me false. bool i = false; switch (idcount) { case 1: i = p1(); break; case 2: i = p1() & p2(); break; case 3: i = p1() & p2() & p3(); break; case 4: i = p1() & p2() & p3() & p4(); break; case 5: i = p1() & p2() & p3() & p4() & p5(); break; case 6: i = p1() & p2() & p3() & p4() & p5() & p6(); break; case 7: i = p1() & p2() & p3() & p4() & p5() & p6() & p7(); break; } return i; I want if one of p*() returns false in any case i returns false. Is it right way or two false returns true? I want all p*() return true i returns true..

#include <stdio.h>

typedef int boolean;

typedef int bool;

#define TRUE (1)

#define FALSE (0)

typedef boolean (* PFuncPtr) (void);

// You can change these as you like

boolean P1() { printf(" P1 \n"); return(TRUE); }

boolean P2() { printf(" P2 \n"); return(TRUE); }

boolean P3() { printf(" P3 \n"); return(TRUE); }

boolean P4() { printf(" P4 \n"); return(TRUE); }

boolean P5() { printf(" P5 \n"); return(TRUE); }

boolean P6() { printf(" P6 \n"); return(TRUE); }

boolean P7() { printf(" P7 \n"); return(TRUE); }

boolean Go(int i)

{

int iLoop;

PFuncPtr P[7];

boolean bReturn = TRUE;

printf(" i = %d \n",i);

P[0] = P1;

P[1]= P2;

P[2]= P3;

P[3]= P4;

P[4]= P5;

P[5]= P6;

P[6]= P7;

if ((i<1)||(i>7))

{

printf(" invalid input: integer must be 1,2,3,4,5,6,7 \n ");

}

else

{

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

{

if (!P[iLoop])

{

bReturn = FALSE;

break;

}

}

}

return(bReturn);

} //Go

int main()

{

boolean bReturn = Go(3);

printf("%d \n",bReturn);

}
