hi, i recieve this error in my programms:iostream.h:no such file or directory

[mobina]

i dont know why i recieve this error in most of my programms. eg:
#include< iostream.h >
int main ( )
{
int a;
int b;
int sum;
cout<<"enter two integer numbers">>
cin>>a>>b;
sum=a+b;
cout<<"sum is"<<sum<<"0"
cout<<a<<"+"<<b <<"="<<sum;
return 0;
}

iostream.h is C++ from before 1998. Most compilers do not ship those antique headers.

Try <iostream>, which is the new header.

None of the standard ANSI C++ headers end in ".h".
