How to catch a divide by zero error in C++?
The following is an example to catch a divide by zero error.
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
Division by zero condition!
In the above program, a function display() is defined with arguments x and y. It is returning x divide by y and throwing an error.
int display(int x, int y) { if( y == 0 ) { throw "Division by zero condition!"; } return (x/y); }
In the main() function, using try catch block, the error is caught by catch block and print the message.
try { c = display(a, b); cout << c << endl; } catch (const char* msg) { cerr << msg << endl; }
