Object is in simple a user-defined data-type.
Methods are different properties of an object.
The above definition shows that 'String' is an object of pre-definied data-type char.
And what about methods? Know if want to add two strings then will not use
str3=str1+str2 directly, but you use strcopy(str3,str1); strcat(str3,str2);
Therefore strcat() & strcopy() are the methods or properties.
