A global variable is one whose value can be used anywhere in the program. Its value can be used in the Main() function and all other functions in the program. However, a local variable is one whose value is local to the function i.e. its value can be used in that particular function only where it is declared. A global variable is defined before the Main() function. Same name can be given to local and global variables. For example in the following program segment

The statement tests the value of a variable against a list of integer or character constants. If the variable matches any of the constants, statements associated with that constant (case) are executed. If there is more than one statement following any case, the statements are enclosed in curly brackets. Value of the switch variable should be provided before the switch statement.

This function causes the program to terminate from any portion of the program and does not have any return value. It has only one argument whose value is returned to the operating system when the program is terminated. This function is included in the <stdlib.h> header file. Hence this header file must be included in the beginning of the program.

Jump statements are used to alter the flow of control unconditionally. That is, jump statements transfer the program control within a function unconditionally. The jump statements defined in C++ are break, continue, goto and return. In addition to these jump statements, a standard library function exit () is used to jump out of an entire program.

The statements that cause a set of statements to be executed repeatedly either for a specific number of times or until some condition is satisfied are known as iteration statements. That is, as long as the condition evaluates to True, the set of statement(s) is executed. The various iteration statements used in C++ are for loop, while loop and do while loop.

Conditional statements, also known as selection statements, are used to make decisions based on a given condition. If the condition evaluates to True, a set of statements is executed, otherwise another set of statements is executed.
