Question

I’ve encountered a problem. I have a code which should read the following text file, delete the last symbol and output the new text in other file. My problem would be: how to delete the last symbol? I’ve tried things like

 for(int j=0;j<10000;j++)
{
    if(simbols[j]=='\0')
    {
        cout<<j;
        minusOne = j-1;
        minusOne ='\0';
        break;
    }
}

But it doesn’t really help and do anything I want. Any help would be appreciated!

P.S.
If it would be any help here’s the full code:

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
char simbols[10000]; int minusOne;
ofstream outFile("outFile.out");
ifstream inFile("inFile.in");

for(int i=0;i<10000;i++)
{
    inFile >> simbols[i];
}

for(int j=0;j<10000;j++)
{
    if(simbols[j]=='\0')
    {
        cout<<j;
        minusOne = j-1;
        minusOne ='\0';
        break;
    }
}

if(outFile.is_open())
{
    for(int l=0;l<10000;l++)
    {
        outFile << simbols[l];
    }
}

inFile.close();
outFile.close();
return 0;

}

It looks to me like you meant to put

simbols[minusOne] = '\0';

instead of

minusOne = '\0';
