c++ program to find the product of two array of integers-clear errors?
 

#include<iostream.h>

int main()

{

int row1[10];

int col2[10];

int m,n,p,q;

cout<<"Enter the number of rows in matrix A"<<endl;

cin>>m;

cout<<"Enter the number of columns in matrix A"<<endl;

cin>>n;

cout<<"Enter the number of rows in matrix B"<<endl;

cin>>p;

cout<<"Enter the number of columns in matrix B"<<endl;

cin>>q;

if(n!=p)

{

int i=0;

cout<<"enter the rows of matrix1"<<endl;

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

{

cin>>row1[i];

int *ptrow= &row1[0];

row1[i]= *(row1+i);

}

cout<<"enter the cols of matrix1"<<endl;

int k=0;

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

{

cin>>row1[k];

int *ptcol2= &col2[0];

col2[k]= *(col2+k);

}

int matpro (int row1, int col2, int (*matpro)(int,int));

{

int pro[i][k];

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

{

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

{

pro[i][k]= row1[i] * col2[k];

int *ptpro= &pro[0];

pro[i][k] = *(pro+i);

pro++;

}

}

      cout << "[" << i << "][" << j << "]: " << pro[i][j];

return(pro[i][k]);

}

}

}

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

A) no code tags
B) this aint the C section.

Fixed. Check the rules.

Re: c++ program to find the product of two array of integers-clear errors?
 

This:

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

Should be this:

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

( no semicolon after k++)

Remove ';' at mathpro

int mathpro(int,int,int)

{

    // math operation

}

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

//  
 

// your code here

//


void matpro(int,int,int);



void main()

{

   // call matpro

   matpro(1,2,3);

}



void matpro(int a,int b, int c)

{

   // implm. here  

}
