Simple Program for Exception Handling with Multiple Catch Using C++ Programming

Definition

To perform exception handling with multiple catch.

Exception Handling with Multiple Catch Algorithm/Steps:

• Step 1: Start the program.
• Step 2: Declare and define the function test().
• Step 3: Within the try block check whether the value is greater than zero or not.
• a.    if  the value greater than zero throw the value and catch the corresponding exception.
• b.    Otherwise throw the character and catch the corresponding exception.
• Step 4: Read the integer and character values for the function test().
• Step 5: Stop the program.

Exception Handling with Multiple Catch Example Program

#include<iostream.h>
#include<conio.h>

void test(int x) {
    try {
        if (x > 0)
            throw x;
        else
            throw 'x';
    } catch (int x) {
        cout << "Catch a integer and that integer is:" << x;
    } catch (char x) {
        cout << "Catch a character and that character is:" << x;
    }
}

void main() {
    clrscr();
    cout << "Testing multiple catches\n:";
    test(10);
    test(0);
    getch();
} 

Sample Output

Testing multiple catches
Catch a integer and that integer is: 10
Catch a character and that character is: x
