Goto is a statement found in many computer programming ... [34] C++ offers an alternative to goto statement for this use case, which is : Resource Acquisition Is ...
C++ compilers prohibit goto or switch from crossing an initialization, as in the following C99 code: void fn ( void ) { goto flack ; int i = 1 ; flack : ; } While syntactically valid, a longjmp() results in undefined behaviour in C++ if the jumped-over stack frames include objects with nontrivial destructors.

In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp. If a function has the return type void , the return statement can be used without a value, in which case the program just breaks out of the current function and ...
goto label The effect of a goto statement is to cause the next statement to be executed to be the statement appearing at (or immediately after) the indicated label. Goto statements have been considered harmful by many computer scientists, notably Dijkstra .
C++14 is a version of the ISO/IEC 14882 standard for the C++ programming language. It is intended to be a small extension over C++11, featuring mainly bug fixes and small improvements, and was replaced by C++17. Its approval was announced on August 18, 2014. [1] C++14 was published as ISO/IEC 14882:2014 in December 2014. [2]

Simple statements are complete in themselves; these include assignments, subroutine calls, and a few statements which may significantly affect the program flow of control (e.g. goto, return, stop/halt). In some languages, input and output, assertions, and exits are handled by special statements, while other languages use calls to predefined ...
->, a pointer operator in C and C++ where a->b is synonymous with (*a).b (except when either -> or * has been overridden in C++). →, goto in the APL programming language; →, representing the direction of a chemical reaction in a chemical equation; →, representing the set of all mathematical functions that map from one set to another in ...
