C++ exception handling code example
Example 1: throw exception c++
#include <stdexcept>
#include <limits>
#include <iostream>
using namespace std;
void MyFunc(int c)
{
if (c > numeric_limits< char> ::max())
throw invalid_argument("MyFunc argument too large.");
}
Example 2: declare and define exception c++
#include <iostream>
#include <exception>
using namespace std;
class myexception: public exception {
virtual const char* what() const throw() {
return "My exception happened";
}
} myex;
int main () {
try {
throw myex;
} catch (exception& e) {
cout << e.what() << '\n';
}
return 0;
}
Example 3: c++ try
try {
} catch (...){
}
Example 4: exception handling c++

using namespace std;
int main () {
