C++ Syntax (Toggle Plain Text) 
  1. #include<iostream.h>
  2. int main()
  3. {
  4. int row1[10];
  5. int col2[10];
  6. int m,n,p,q;
  7. cout<<"Enter the number of rows in matrix A"<<endl;
  8. cin>>m;
  9. cout<<"Enter the number of columns in matrix A"<<endl;
  10. cin>>n;
  11. cout<<"Enter the number of rows in matrix B"<<endl;
  12. cin>>p;
  13. cout<<"Enter the number of columns in matrix B"<<endl;
  14. cin>>q;
  15. if(n!=p)
  16. {
  17. int i=0;
  18. cout<<"enter the rows of matrix1"<<endl;
  19. for(i=0;i<=m;i++)
  20. {
  21. cin>>row1[i];
  22. int *ptrow= &row1[0];
  23. row1[i]= *(row1+i);
  24. }
  25. cout<<"enter the cols of matrix1"<<endl;
  26. int k=0;
  27. for(k=0;k<=;k++;)
  28. {
  29. cin>>row1[k];
  30. int *ptcol2= &col2[0];
  31. col2[k]= *(col2+k);
  32. }
  33. int matpro (int row1, int col2, int (*matpro)(int,int));
  34. {
  35. int pro[i][k];
  36. for(i=0;i<m;i++;)
  37. {
  38. for(k=0;k<=q;q++)
  39. {
  40. pro[i][k]= row1[i] * col2[k];
  41. int *ptpro= &pro[0];
  42. pro[i][k] = *(pro+i);
  43. pro++;
  44. }
  45. }
  46.       cout << "[" << i << "][" << j << "]: " << pro[i][j];
  47. return(pro[i][k]);
  48. }
  49. }
  50. }

it is showing errors like

C++ Syntax (Toggle Plain Text) 
  1.  expected primary-expression before ‘;’ token
  2. 27: error: expected `)' before ‘;’ token
  3. 27: error: expected primary-expression before ‘)’ token
  4. :27: error: expected `;' before ‘)’ token
  5. :36: error: expected `)' before ‘;’ token
  6. :36: error: expected primary-expression before ‘)’ token
  7. :36: error: expected `;' before ‘)’ token
  8. :48: error: expected `}' at end of input
  9. :48: error: expected `}' at end of input
  10. 48: error: expected `}' at end of input
  11.

This:
for(k=0;k<=;k++;)
Should be this:
for(k=0;k<=;k++) ( no semicolon after k++)

Remove ';' at mathpro
C++ Syntax (Toggle Plain Text) 
  1. int mathpro(int,int,int)
  2. {
  3.     // math operation
  4. }

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?
C++ Syntax (Toggle Plain Text) 
  1. int matpro(int row1[i],int col2[k],int pro[i][k]);
  2. pro[i][k]  += pro[i][k]+  (*matpro)(&row1[i],&col2[k]);
  3.       cout << "[" << i << "][" << k << "] " << pro[i][k];
  4. return(pro[i][k]);
  5. void matpro(int row1, int col2, int (*matpro)(int &row1,int &col1));

Vahny, this is your last chance. I told you before to USE CODE TAGS.

So what's the problems. Declare the method before using them..Example..
// CODE TAG
//   
 
  
 C++ Syntax (Toggle Plain Text) 
 
 
 
  1.  
  2. // your code here
  3. //
  
 

void matpro(int,int,int);

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

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