Question

#include<iostream>
using namespace std;

void callMe()
{
    int count=0;
    cout<<"I am called "<<++count<<" times!\n";
}

int main()
{
    callMe();
    callMe();
    callMe();
    callMe();
    return 0;
}

In this case, the output will be

I am called 1 times!
I am called 1 times!
I am called 1 times!
I am called 1 times!

Instead, I want the output printed as

I am called 1 times!
I am called 2 times!
I am called 3 times!
I am called 4 times!

Answer 1

I hope that the following code snippet will solve your issue!

#include<iostream.h>

void callMe()
{
    static int count=0;
    cout << "I am called " << ++count << " times!\n";
}

int main()
{
    callMe();
    callMe();
    callMe();
    callMe();
    return 0;
}

Here the static variable will retain its value and it will print the count incremented each time!
