C + + Learning Path: Try&catch statement block handling exceptions

Skip catch to continue execution of subsequent code if no exception is caught

Try & Catch is a block of statements that is very useful for handling exceptions. More practice.

Here is an important template

#include <iostream>#include<string>#include<vector>#include<stdexcept>using namespacestd;//Different catch blocks can be taken for different exceptions to capture//for a part can be processed uniformlyintMainintargcConst Char*argv[]) {    Try    {        inti; CIN>>i; if(i = =0)            ThrowRuntime_error ("run-time error occurs"); Else if(i = =1)            ThrowInvalid_argument ("Illegal parameters"); Else if(i = =2)            ThrowLogic_error ("Logic Error"); Else            ThrowOut_of_range ("Out of bounds error"); }    Catch(...)//can catch all the anomalies    {        }    Catch(Exception &e) {cout<<"Exception Information:"<< e.what () <<Endl; }    Catch(Runtime_error &e) {cout<<"Runtime_error:"<< e.what () <<Endl; }    Catch(Invalid_argument &e) {cout<<"invalid_argument:"<< e.what () <<Endl; } cout<<"Continue running"<<Endl; return 0;}
