How to throw a C++ exception?
Exception handling is used to handle the exceptions. We can use try catch block to protect the code. Exception can be thrown anywhere within the code block. The keyword “throw” is used to throw an exception.
Here is an example of throw in C++ language,
Example
#include <iostream>
using namespace std;
int display(int x, int y) {
if( y == 0 ) {
throw "Division by zero condition!";
}
return (x/y);
}
int main () {
int a = 50;
int b = 0;
int c = 0;
try {
c = display(a, b);
cout << c << endl;
} catch (const char* msg) {
cerr << msg << endl;
}
return 0;
}Output
Here is the output
Division by zero condition!
