A strongly-typed programming language is a language that requires all variables to be declared with a specific data type, and all type-checking to be performed by the compiler. This allows the compiler to catch type errors during compilation, and can help to prevent errors at runtime.
Is C++ strongly typed?
Yes, C++ is a strongly typed language. This means that every variable and expression has a specific type, and that type cannot be changed without explicitly casting the variable or expression to a different type. This allows the compiler to catch many errors at compile-time, before the program is even run.
Is Python a strongly typed language? Yes, Python is a strongly typed language. This means that every value has a specific type, and every type has a specific set of values that it can take on. For example, an integer can only take on numerical values, and a string can only take on textual values. This ensures that all values are well-defined and that no type-casting is necessary.
Is C# a strongly typed language?
Yes, C# is a strongly typed language. This means that, in general, you must declare a variable before you can use it, and you must specify the type of data that the variable will hold. For example, the following code declares a variable of type int and assigns the value 42 to it:
int myVariable = 42;
If you try to assign a value of type string to this variable, you will get a compile-time error. Why is C not strongly typed? C is not a strongly typed language because it does not enforce type checking at compile time. This means that type errors can go undetected until runtime, which can lead to unexpected results.
Is C++ statically-typed? Yes, C++ is a statically typed language. This means that once a variable is declared with a certain type, it cannot be changed to another type. For example, a variable of type int can only store integer values and cannot be changed to store double values.
