Tokens are the fundamental building blocks of a C++ program that represent the smallest individual units of a program. These tokens are classified into various categories such as keywords, literals, identifiers, operators, punctuators, and preprocessors.
Examples of CPP tokens:
1. Keywords: Keywords in C++ are reserved words that have predefined meanings in the language. For example, 'int', 'float', 'if', 'else', etc. Here is an example:
int main() {
return 0;
}
Package/Library: Standard C++ Library.
2. Literals: Literals are constant values that are used in a C++ program. For example, '123', '3.14', 'true', and 'false'. Here is an example:
int num = 123;
bool flag = true;
Package/Library: Standard C++ Library.
3. Identifiers: Identifiers are names given to various elements in a program such as variables, functions, classes, and objects. For example, 'x', 'y', 'z', etc. Here is an example:
int x = 5;
string name = "John";
Package/Library: Standard C++ Library.
4. Operators: Operators are symbols that represent various operations in a C++ program such as arithmetic, relational, logical, and bitwise operations. For example, '+', '-', '*', '/', '>', '<', '==', etc. Here is an example:
int x = 5, y = 10;
int z = x + y;
Package/Library: Standard C++ Library.
5. Punctuators: Punctuators are symbols used to group or separate expressions in a C++ program such as parentheses, curly braces, commas, semicolons, etc. For example, '{', '}', '(', ')', ',', ';', etc. Here is an example:
for(int i = 0; i < 10; i++) {
// do something
}
Package/Library: Standard C++ Library.
6. Preprocessors: Preprocessors are instructions that are executed before the compilation process to control various aspects of a program. For example, '#include', '#define', '#ifdef', etc. Here is an example:
#define PI 3.14
Package/Library: Standard C++ Library.
