what is difference between int.parse and convert.toint32 in c#?
606145
ToInt32 are used to convert string into the integer but Only difference between them is to Convert. ToInt32 handle null and returns '0' as output and int. parse is not going to handle NULL and will give a Argument Null Exception. Here is the example for that both are almost same except handling null.

int is not object, its a primitive type. Primitive types aren't objects, but are stored directly in whatever context they are needed. If they need to be treated like an object, they can be boxed in an Integer.

The basic difference between type conversion and type casting, i.e. type conversion is made “automatically” by compiler whereas, type casting is to be “explicitly done” by the programmer. ... When the two types are compatible with each other, then the conversion of one type to other is done automatically by the compiler.

The method generally used to convert String to Integer in Java is parseInt(). How to use parseInt() method in Java? There are two variants of this method: public static int parseInt(String s) throws NumberFormatException - This function parses the string argument as a signed decimal integer.

NSInteger is a type definition that describes an integer - but it is NOT equivalent to int on 64-bit platforms. You can examine the typedef by cmd-clicking on NSInteger in Xcode. NSInteger is defined as int when building a 32-bit app and as long for 64-bit apps.

There are many ways to convert an Integer to String in Java e.g. by using Integer. toString(int) or by using String. valueOf(int), or by using new Integer(int). toString(), or by using String.

The basic difference between the type int and long is of their width where int is 32 bit, and long is 64 bits. ... In Java, the range of type int is from –2,147,483,648 to 2,147,483,647 whereas, the range of type long is from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 which is very much greater than type int.

int is a datatype for a variable storing integer values. static int is a variable storing integer values which is declared static. ... Every time the function gets called, i gets initialized, its value gets incremented to 1 and gets destroyed when the function ends. Now lets see the same example with static int.

Type Conversion is the conversion of object from one data type to another data type. Implicit Type Conversion is automatically performed by the Python interpreter. ... Explicit Type Conversion is also called Type Casting, the data types of objects are converted using predefined functions by the user.

Visual Basic supplies several numeric data types for handling numbers in various representations. Integral types represent only whole numbers (positive, negative, and zero), and nonintegral types represent numbers with both integer and fractional parts.

In JavaScript “0” is equal to false because “0” is of type string but when it tested for equality the automatic type conversion of JavaScript comes into effect and converts the “0” to its numeric value which is 0 and as we know 0 represents false value. So, “0” equals to false.

Basically, an int is read/write and a const int is read only. You use a const int for something that never changes value, such as a pin number. The advantage is less memory is used.

Both data types are stored as signed binary integers. INTEGER values have 32 bits and can represent whole numbers from –2 31–1 through 2 31–1. SMALLINT values have only 16 bits. They can represent whole numbers from –32,767 through 32,767.
