perform exception handling for Divide by zero Exception.

Exception Handling Divide by zero Algorithm/Steps:

Step 1: Start the program.
Step 2: Declare the variables a,b,c.
Step 3: Read the values a,b,c,.
Step 4: Inside the try block check the condition. (a. if(a-b!=0) then calculate the value of d and display.b. otherwise throw the exception.)
Step 5: Catch the exception and display the appropriate message.
Step 6: Stop the program.

Exception Handling Divide by zero Example Program

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

void main() {
    int a, b, c;
    float d;
    clrscr();
    cout << "Enter the value of a:";
    cin>>a;
    cout << "Enter the value of b:";
    cin>>b;
    cout << "Enter the value of c:";
    cin>>c;

    try {
        if ((a - b) != 0) {
            d = c / (a - b);
            cout << "Result is:" << d;
        } else {
            throw (a - b);
        }
    } catch (int i) {
        cout << "Answer is infinite because a-b is:" << i;
    }

    getch();
}

Sample Output

Enter the value for a: 20
Enter the value for b: 20
Enter the value for c: 40

How It Works

This C++ program demonstrates Simple Program for Exception Handling Divide by Zero. It first reads the required values as input, then uses conditional logic to decide the result, and finally prints the output shown in the Sample Output above.

Declare the variables that hold the program’s data.
Read the input values that the program will work with.
Use conditional statements to handle the different cases.
Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
