من عرف c++

write a c++ praram to accept 3*3 matrix elements and compute the sum of amatrim and display?
انا ما عرف ما هو خطا من يعرف ++c ارجو مساعدة


#include <iostream.h>
void main()
{
float m[3][3];
int i,j,sum=0;
cout<<"enter 9 numbers \n";
for (i=0;i<3;i++)
for (j=0;j<3;j++)
cin>>m[i][j];
cout<<"the enter 9 numbers are \n\n";
for (i=0;i<3;i++)
{
for (j=0;j<3;j++)
cout<<m[i][j]<<" ";
cout<<"\n";
sum=i+j;
cout<<"sum of all numberss is : " <<sum;
}
}

تفضل:



int main(int argc)
{
float m[3][3];
int i,j,sum=0;
cout<<"enter 9 numbers \n";
for (i=0;i<3;i++)
for (j=0;j<3;j++)
cin>>m[i][j];
cout<<"the enter 9 numbers are \n\n";
for (i=0;i<3;i++)
{
for (j=0;j<3;j++)
{
cout<<m[i][j]<<" ";
cout<<"\n";
sum += m[i][j]; //-- here was your biggest mistake !!!
// -- we can also use: sum = m[i][j] + m[i][j];
}
}

cout<<"sum of all numberss is : " <<sum;
cin.get(); // to pause the screen...
return 0;
}
