Hey i am new to use C++...
This is one part of my 200 line calculator and the problem is the Name...

else if (x==4)
{float bmi,h,w,age;
char name[20], wat;
cout<< " Type your name \n\n";
cin>>gets(name);
cout<< " Type your age \n\n";
cin>>age;
cout<< " Enter your height.....\n\n ";
cin>>h;
cout<< " Enter you weight in kg.....\n\n";
cin>>w;
cout<<endl<<endl;
bmi=(w/(h*h)*10000);
cout<< " Name   :   ";puts(name);cout<<endl<<" Age  :    "<<age<<endl<<"\n BMI INDEX    :   "<<bmi;
}

I am getting this output

Type your Name

Raheel Ahmed
Type your age


Enter your Height


Enter your Weight



Name: Raheel
Age: 
BMI Index: 2e+12.322432 (bla bla doesnt matter) 

Why isn't my full name displayed and i cant neither type the other datas??
Note: Use Same Funtions

Don't mix gets with std::cin. Instead use a simple std::string.

The default behaviour for std::cin is to truncate the read operation on a whitespace. Hence only the first part of your name is read in the variable name.

Thereafter the program tries to read your age. It expects a float but it gets a string "Ahmed". Hence std::cin goes into error state and further read operations fail.

Instead try:

std::string name; 
char wat;
cout<< " Type your name \n\n";
// read the entire line upto '\n' character
getline( std::cin, name );
