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;
}

شكر والحل هو

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