How to convert a single char to int in C? ++Decimal function in Python

The following is an example of catching a zero division 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 Result

Division by zero condition!

In the above program,display()A function is defined using parameters x and y. It returns x divided by y and throws an error.

int display(int x, int y) {
　　　if (y == 0) {
　　　　　　throw "Division by zero condition!";
　　　}
　　　return (x/y);
}

In thismain()In the function, use the try catch block to capture errors to the catch block and print the message.

try {
　　　c = display(a, b);
　　　cout << c << endl;
} catch (const char*　msg) {
　　　cerr << msg << endl;
}
