it is showing errors like

expected primary-expression before ‘;’ token
27: error: expected `)' before ‘;’ token
27: error: expected primary-expression before ‘)’ token
:27: error: expected `;' before ‘)’ token
:36: error: expected `)' before ‘;’ token
:36: error: expected primary-expression before ‘)’ token
:36: error: expected `;' before ‘)’ token
:48: error: expected `}' at end of input
:48: error: expected `}' at end of input
48: error: expected `}' at end of input

And here's another one, in the following snippet k stops when it is more than what? Or, if you prefer, complete the following if k is less than or equal to what:

for(k=0; k<= ; k++; )

I've modified the programlike this, but its still not working:What's probem with this function?

int matpro(int row1[i],int col2[k],int pro[i][k]);
pro[i][k]  += pro[i][k]+  (*matpro)(&row1[i],&col2[k]);
      cout << "[" << i << "][" << k << "] " << pro[i][k];
return(pro[i][k]);
void matpro(int row1, int col2, int (*matpro)(int &row1,int &col1));

The semicolon are removed, but errors exist in the function defintion.

Vahny, this is your last chance. I told you before to USE CODE TAGS.
Click "Member Rules" and its all explained in there

So what's the problems. Declare the method before using them..Example..

// CODE TAG
// [code] 
// your code here
// [/code]

void matpro(int,int,int);

void main()
{
   // call matpro
   matpro(1,2,3);
}

void matpro(int a,int b, int c)
{
   // implm. here  
}
