C++ help please?

would anybody be able to help me with this?








bool isReflexive (const int mat[N][N], int size) {


// ????????????????????????


return 0; // fix return


}





// returns whether or not a Matrix is Symmetric


bool isSymmetric (const int mat[N][N], int size) {


// ????????????????????????


return 0; // fix return


}





// returns whether or not a Matrix is Transitive


bool isTransitive (const int mat[N][N], int size) {


// ????????????????????????


return 0; // fix return


}





// returns whether or not a Matrix is an Equivalence Relation


bool isEquivalenceRelation (const int mat[N][N], int size) {


// ????????????????????????


return 0; // fix return


}

C++ help please?
this would be easier to answer if you provided the formulas for each function... for example:





symmetric matrix:





aij = aji





then we can use this lines for the isSymmetric function:


bool isSymmetric (const int mat[N][N], int size) {


int i, j;


for(i=0;i%26lt;=size;i++ {


for(j=0;%26lt;=size;j++) {


if(mat[i][j] != mat[j][i]) {


return 0;


}


}





}


return 1;


}





this code checks every value inside our mat[][] array if the condition aij = aji is satisfied if it is.. we will return 1 if at least 1 of the values inside of mat[][] does not conform to the condition then we return 0





please show the conditions for reflexive, transitive and equivalence... but basing from the code above i think you can make your own algorithm for the other functions :D





good luck
