	cout << "-----------------------------------\n";
	int a;
	int b;
	int sum;
	a=29;
	b=30;
	sum=a+b;
	cout << " The sum of "<< a << " and "<<b <<" is : "<< sum <<"\n\n" ;
}

Sample Output:

 Print the sum of two numbers :

C++ Programming: Tips of the Day

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
